Kaveri: Current Situation in Karnataka's Dams

Background: It is the second week of September 2016. A very bad week in south India. Lot of disturbance, violence, animosity etc. It is that season of the year where Supreme Court gets involved and Kaveri is a big topic. This year, it went way worse than the previous few years due to many reasons. 

1. In 2012, I had written a comprehensive writeup on what is the Kaveri issue, what are the issues from Karnataka's side, what are the issues from Tamil Nadu's side, and how this can be solved in the long run - Kaveri River Water Sharing : What Are The Solutions? I had listed 10 solutions, based on what I read from experts. Now more solutions have come up too, like desalination. 
2. In 2016, The same has been used in this better articulated Quora answer. - How can the Cauvery (Kaveri) river issue be solved?

For those who want long term solutions, and points of view from both states, please spend time in those links, and also check out references from each. You will learn a lot about actionable steps!

This analysis is Not for YOU: And those who are busy distributing violence videos, sarcastic or insulting memes, chest beating that Kaveri is only "ours", please continue doing that. Don't read this any further. Because my intention is not to discuss any point that is fruitless when it comes to final water sharing details. I am more focused on actual figures, statistics and actionable steps.

What is the water situation in Karnataka in September 2016? Now the rest of this writeup would be purely showing the water situation in Karnataka's Kaveri basin as of September 13th, 2016. This is fully using a fantastic analysis done by a Twitter user named V Vinay - @ainvvy . He calls himself a curious academic entrepreneur. Again, all the information provided from this point on wards, is only from Karnataka's dams, as I did not see any qualitative analysis or data from Tamil Nadu's dams. If you know, please share in the comments and I will update here.

Names of Dams: Mr. Vinay managed to download the daily inflow and reservoir levels at the 4 Karnataka dams: Harangi, Hemavati, KRS, and Kabini.

Water Measurements: Before getting into the data, we need to understand TMC and cusecs. For historical reasons, the measurement is in terms of cubic feet. 1 cubic feet is roughly 28.3 litres of water. cusec stands for cubic feet/second. Or as @sheksis joked, 28 Bisleri bottles/second... More relatable :)

What did Supreme Court say on 12th September 2016 in the modified order? 

The current SC order for example asks Karnataka (KA) to release 12,000 cubic feet of water every second. TMC is a thousand million cubic feet, which is a billion cubic feet of water. This is 1,000,000,000 = 10⁹ = 1 billion cubic feet. Also, important to note that this has NO component of time involved here. It is just a measure of water. 

So if 10,000 cusecs of water is released for a day, it amounts to 0.86 TMC of water. 15K cusecs amounts to 1.3 TMC a day.

In Human usage terms: To get a sense for these numbers, how much of water is used for drinking, washing cloths, bathing etc. In other words how much water is needed for human in Indian terms, per day? It is usually taken to be about 100 Litres per person per day. This translates to a little over 3.5 cubic feet of water. Do not compare with other countries where more water is available per capita. @abhicrux said, 135 liters/person/day is used for standard hydraulic calculations. All uses included. Rural south India gets less than 100 liters today. So we will go with 100 liters on the average side per person, in a water starved south India. 

Drinking Water Needs of Karnataka's Kaveri basin: The estimated number of people in Bengaluru, Mysuru, Mandya and other Kaveri basin areas is about 1.6 to 1.8 crores. This amounts to about 0.063 TMC of water a day. Let's call it drinking water, even though it is for other daily use purposes too. Essentially anything that is not related to irrigation which is the primary user of Kaveri water. Note that not all parts of Bengaluru get Kaveri water. This computation is only for the areas getting Kaveri today.

Taken over a year, it amounts to about 24 TMC of water. This is the water that the state needs to have to take care of drinking water needs. Of course, there will be losses of all sorts, so the figure is likely to be more like 35-40 TMC. Losses are usually in the form of evaporation loss, distribution loss and leakage from dams and pipes.

Water in Dams of Karnataka: Now let us get back to the 4 dams. Harangi has a storage capacity of 8 TMC, KRS in Mandya district has 45 TMC. This is the biggest and the most important reservoir in south Karnataka. Hemavati has 35 and Kabini has 16. That totals to about 104 TMC that can be stored MAX by Karnataka at any given point of time. With around 750 TMC of water estimated for Kaveri river as a whole in a good monsoon year, this is about 14% of Kaveri water that can be stored by Karnataka, at any point in dams.

This is the capacity. Current levels as of September 13th 2016 are at about 5 in Harangi and about 10 in the remaining three. They add up to 35 TMC in total across ALL dams in Karnataka on Kaveri basin. All these are computed with live storage of water without getting into dead storage analysis (which amounts to water that can't be released from dam at the bottom). An additional discharge at the current levels of 12000 cusecs to TN over the next 8 days will mean 8.3 TMC of water. Since some of the water will surely be released for other purposes, and with some inflow, the likely level in 8 days is 25 TMC. Again 25 TMC in total across ALL dams in Karnataka on Kaveri basin. This 25TMC is what we will have to survive with until June-July of 2017 when you will see south west monsoon filling in dams again. That is at least 9 full months with 25 TMC of water, if no further rains happen :(

What about farmers in Karnataka? Forget irrigation using above mentioned water levels. Farmers are screwed in Karnataka for this year! You need 100 to 150 TMC of water for irrigation for rest of the year in Karnataka. Not sure if they could even get one full crop this year, while Tamil Nadu is planning for the second crop now, and might get a third crop also early next year. This is the fundamental reason why Karnataka was burning for days in September 2016.

Dynamics of Dams and Inflow Analysis: Let’s look at the dynamics of the dams. Vinay's data starts from 2011. So we have about 5.5 years of data. Here is a table of the total inflow into various dams. Kabini has small capacity but matches Hemavati in inflow.

As you can see, Harangi and Hemavati sit behind KRS, while Kabini is ‘independent’ and joins later.

Keep in mind that some outflow from Hemavati can be inflow to KRS, etc. Vinay focuses on KRS and Kabini to look at the data more closely.

Here is Kabini. Most of the water in the months of June to September.
And then the inflow dies down. Look at September. This time we are done through about 10 days. And the inflow has been a mere 1.5 TMC!

Likewise, KRS dam near Mysuru, has got an inflow of 3.3 TMC for the first 10 days of this month. Will it hit 10 for the month?

Then Vinay plotted the reservoir level and inflow for KRS. This graph is revealing. Notice how the reservoir level shoot up at monsoon (where the inflow is heavy) and how it progressively decreases until the next. There are small inflows in between, but noting compared to what happens during the monsoon.

And notice the 2016 inflows and reservoir levels. It is quite pathetic. So the usual inflow after monsoon will also be limited this year. Usually, post September of any year, the inflows are about 25-30 TMC. We don’t see it happening this time. But we don’t have enough data to predict.

What's for Karnataka for rest of 2016 and first half of 2017? It is going to be a very tough year at this side of Karnataka. Farmers are already ditched for 2016. Drinking water might be barely sustained at the current storage levels, for the next 9 months. See above graphs and inflow analysis.

Vinay says that Tamil Nadu gets two monsoons and has better groundwater than Karnataka. Some people are disputing this two monsoon theory, but what Vinay means is that Tamil Nadu gets both South West and North East monsoons. Remember Chennai floods in 2015? That was the North East Monsoon season.

After reading this analysis, it became very clear why Karnataka farmers and Kaveri delta drinking water users, are absolutely outraged at the current situation of draining the remaining precious water from dams. Every TV channel in Karnataka is saying the same thing - We have no drinking water.. why are we being forced to leave the remaining water for growing 2nd crop in Tamil Nadu? Drinking water takes precedence over everything else when it comes to human needs. 

Any Suggestion for Politicians of TN and KA? The two states need to demonstrate better sense than landing in court every time there is a distress. Lack of sagacity is the problem. For those who say the Supreme Court would have ‘looked’ at the data and come to the conclusion, Vinay says, he does not know. These graphs don’t seem to suggest so…

There is more in the data, but Vinay says that he will take it up on some other day.  Vinay got all these data using a simple python program… shouldn’t take more than 20 minutes for a programmer to write.

Let's stop here, hoping wisdom prevails all around. I don't think a blog or set of tweets can change politics, courts or tribunal happenings, but this is only meant for common people like you and me, to understand the dire situation in Karnataka today.

Source of Data for Karnataka's dams and water levels: https://www.ksndmc.org/Reservoir_Details.aspx

I wish I could find similar data on Tamil Nadu's dams starting with Mettur for September 2016, to see how good or bad the situation is for Tamil Nadu farmers. Again, if you have similar data from TN, please do share.

Thanks again, Mr. Vinay for a classic analysis.

Dear Goverments, please keep off Hindu Temples

Tonight, went to Samaya TV to discuss on the news that the famous Dharmasthala Manjunatha temple was being considered to be taken over by the govt.

One senior Jyotishi told things about the Kshetra. Not much arguments.

The core arguments were between me and Talakadu Chikka Rangegowda. It was well anchored by Aravind. This is my second presence as a panelist in Aravind's show.

As usual, the pro government take over arguments were on "mismanagement", "Why should Jains run Hindu temple", "there have been complaints against the Dharmadhikari" etc..

My points were:

1) I am a Bhakta of Dharmasthala temple. I go there voluntarily. I give money on my own. I trust the good work is done by the Trust headed by a Jain. I have absolutely no issue that they are Jains. They are running awesome anna dana. Kitchen Annapurna featured in June 2015 Mega Kitchen National Geographic Channel. Their educational and other institutions are doing wonderful job. For 800 Years, Jain Bunt Heggade Pergade family has administered it splendidly. 21 Dharmadhikaris have come to this seat till date. Government's job is to provide basic facilities and govern. I drove 15 KM to the studio and 10KM were in "Kattale Bhagya" power cut. When the govt can't take care of basic things, why they heck are they wanting to take over well run temples?

2) pSeculars always want Hindu temple money by giving some or the other excuse. Let's stop this now. Why should govt control 35,000 Hindu temples in Karnataka? Why should other states like TN control similar count of Hindu temples? Are all these having mismanagement? There are 164 A category and 283 B category temples with KA govt. Were all these managed by "other religions", before take over? Govt just wants money. And some excuse. I gave examples of how very simple excuses were used by governments to take over cash cows.

3) Talking of mismanagement, there was a murder of a Church father (KJ Thomas) in Bengaluru. There were large scale Wakf land grab amounting to 2 lakh crore as reported by Anwar Manippady. Should the govt take over churches and mosques/dargahs citing mismanagement, murder or other issues?

4) When I heard that only Hindus should manage Hindu temples, I showed that Mohammed Ali, First Division Assistant appointed by the govt in Bengaluru Rural district to manage Mujrai or Endowments department. I don't want a Muslim to manage Hindu temples. Hindus have managed for 1000s of years, and will easily manage ourselves. This argument seriously hurt Mr. Gowda as he saw the hypocrisy of opposing Jains, but having been forced to support Muslims!

5) If there is a big issue with Dharmasthala, people can file an FIR file. If no action taken approach the Magistrate directly. Or file PIL file if land is an issue. Why is the police there? Use them. Instead, trying Govt executive order to grab temple is not something we will allow.

6) I gave examples of Sahasralingeshwara temple of Uppinangady fighting with Karnataka Govt's Mujrai department's 1997 act. The 2007 judgment clearly said that the Endowments act itself is unconstitutional. Google for "Karnataka High Court Sri Sahasra Lingeshwara Temple vs State Of Karnataka on 8 September, 2006".

The judgment concluded: 

"We have already ruled that the Act is hit by Articles 14 and 26 of the Constitution of India. We have further ruled that it is not possible to severe them. Hence, we deem it proper to strike down the entire act and consequently strike down the notification as un constitutional." 

Use this wherever you see temple issue with govt. Governments can't and should not take over temples.

7) I also gave the example of Chidambaram Natarajar temple in Tamil Nadu. The judgment of 2014 January 10th, gave Podu Dikshitars a big victory in a century old case. If Endowments department of a state govt takes over a temple there should be a reason. Merely issuing show cause and circular is not right. Once you take over you will have 2 years or so to rectify it; notification should mention what reason - only take over mismanagement of temple affairs. This was Dr. Swamy's famous case. The 1951 take over of TN govt was deemed unlawful. Dikshitars had printed temple constitution in 1849 itself. Was opened to all castes of Hindus. This point stumped the others and there is not much they could say on this.

Overall; My repeated stress was that Hindus have freedom of religion like everyone else. If there are issues, let other parts of constitution address them (like theft, mismanagement etc.). So called secular government taking over temples violates Articles 14, 25, 26 and 27 of Indian constitution. As a Hindu, I don't want any temple to be managed by the government. Government's job is to take care of power, water, security and other basic necessities. Hindus know how to manage temples and they have been doing it for 1000s of years. Leave our temples alone.

#KeepOffHinduTemples

I think it went on well. If a video is uploaded by Samaya News, I will share here.

Education in Matrubhasha

Yesterday  the Supreme Court of India came up with a very significant judgement.

It was a long process and involved judgment, but the summary was this.

"No government can force a student to chose his or her medium of education. It of course means, the parents or guardians of the child have absolute right to pick any medium of education for their children."

And a few of this morning's front pages in Kannada news paper world.

"Setback to Kannada"

Vijayavani

"Kannada Medha", roughly meaning the sacrifice of Kannada. 
"Public opinion is that this verdict is against the very concept of linguistic states"
"Central government (UPA) has kept mum on this topic"

Kannada Prabha

"English medium not accepted"
"A result due to the lack of experts"

Samyukta Karnataka

 "Can't force medium of education says SC"

Udayavani

Overall, a situation of gloom in Karnataka. 6 to  8 news TV channels in Kannada were abuzz since yesterday itself that this is a big setback to Kannada language.


Before anyone starts wondering why I am writing this, the issue is closer to my heart. I am a product of Kannada medium schooling and it worked very well for me even when I switched to English medium for higher education. My medium of education never became a hurdle even when working in top levels in IT industry for long number of years. In fact, the ease with which we could pick up Maths, science, social studies etc. when taught in our mother tongue, was something I am quite happy about.

Now some observations:

In my view, most Kannada papers and news channels are overreacting. Activists are also over reacting. Supreme Court's constitution bench has quoted Article 19 (1) to arrive at this judgment. No government or organization can go against the constitution.

Secondly, this is not anything specific to Kannada or Karnataka. The same judgment will be held as a benchmark, like the SR Bommai case in article 356, for other states too in the future. This is a landmark judgment that will have long term effect.

Thirdly, there is no need to beat the chests that there's been a "defeat" or "setback" to Kannada. Look at the actual reality. Nearly 74% of the one crore students in Karnataka are ALREADY studying in Kannada medium. All the government has to do is to make sure that the quality of education for these folks, plus those 6% studying in other Indian languages, is at the same level as the 20% who are studying in English medium. Can they do it? That's the big challenge.

Fourthly, the state government already has control over 69% of the schools in Karnataka. They are either fully government owned or government aided. Made the quality of education in here top notch, and the 2 to 3% shift happening each year to private schools will slow down. Why do parents send kids to private schools that mostly teach in English medium? Because they want "better" education and "better" career. If the government or aided schools can provide the same at competitive levels, who would pay higher amount to switch to private unaided schools anyway?

Fifthly, India has nearly 1400 mother tongues. When a continent sized country with so many mother tongues are in place, it is extremely difficult to come up with any kind of language formula. The three language or two language formulae have to factor in the important fact that English is as Indian today, as any other Bharatiya language. Take the examples of Poschim Bongo or Uttar Pradesh. Opposing English just won't work as ordinary parents for the past 3 generations are seeing English as a way for their children's "better" career. The governments need to understand the "better" part well. Then everything will fall in place. So far there is no practical linguistic policy for schools, that make every Indian boy or girl go through equal linguistic difficulty level, yet practical enough to earn living in the future. Presenting here a quick summary sheet on the language categories of India that I had prepared earlier. There may be crores, or even 10s of crores of Indians who might not have practical access to their mother tongue medium of education, strictly following the freedom that the Supreme Court outlined. In my view, crores of children already might be forced to go through a medium of education that is already violating the Supreme Court's judgment, across India.

Lastly, no one is opposing teaching Kannada or other language. The issue is with forcing the medium of education. If a large group of people, like 25 to 35% in the state now, mostly in urban areas, see a value in English medium education, the governments and activists have to sit back and think.

• Why are they preferring English? Is it blind westernization? 
• Is it better salaried jobs for English medium educated students compared to Kannada or other Bharatiya language educated students? 
• Is it the poorer quality of education in Bharatiya language schools in most cases? 
• Is it much beyond language like Science/Math which are easy to learn in English medium? 

What needs to be done? 

It's time for experts to talk to 1000s of parents.. Maybe lakhs. Find out what is working in English medium and why people are even willing to fight for 20 years in courts, all the way to Supreme Court to oppose imposition of medium by the government?

I feel that the majority of the parents won't be against Kannada or other Bharatiya langauges that they speak at home. Their focus will be more business oriented. Investment on their children for a better return for them and children in the future. When a vast chunk of urbanized parents, and now even semi-urban parents, are thinking in education as investment, the government has only ONE option. To make the schools under its control supremely competent a global level. Then everything will fall in place. That's my opinion.

What do you think?

Kaveri River Water Sharing : What Are The Solutions?

Kaveri or Cauvery river is one of the 7 holiest rivers for Hindus. In many Dharmic poojas, the water filled into the kalasha or holy vessel, is adored with a chant. "Gange cha Yamune chaiva, Godavari Saraswati. Narmada Sindhu Kaveri, Jalesmin Sannidhim Kuru". It essentially means the water being used for the worship of Bhagawan or Bhagawati, is as sacred as the combination of all 7 holy rivers.

Mother Kaveri's Statue. {Source: Deccan Herald}

Kaveri is the "Jeeva Nadi" or life sustaining river. It is very highly revered by both Kannada (also Kodava) and Tamil people. You can hear 100s of celebratory songs like the super hit song Kodagina Kaveri . You can also see many customary celebrations like Aadi Perukku which is a very special time for Kaveri delta people. In short, SHE is the mother for those who live along its banks.. and SHE is theirs! These people do not understand the artificial linguistic state formation boundaries, politics, courts and other systems.

But today, when you hear Kaveri, what comes to your mind? If you are a person from Tamil Nadu (or Pudhucherry for some part) the "villain" is a state to the north west, Karnataka. If you are from Karnataka (or to some extent Kerala), the "villain" is a state to the south east, Tamil Nadu. And, this is not something that is for just 2012 or 2007 or 2002 or 1991.. this is happening for over 200 years now. The holiest of rivers adored and worshiped as "Kaveri Maata" or Mother Kaveri, has become a humongous political, agricultural, legal, economic and propaganda fight in South India. It does not even leave students or movie industry folks..

Why did this happen? How did this happen? Is there any way out, even if the process is gradual?

For that some basics will be needed. No, I am not going to present every detail about how the dispute got magnified till this time. There are enough resources in internet, court papers, government documents and in media for you to read through. Also, if you are reading till here, most likely you have a special interest in this case, as for most India out of South India, this is just one of those "burning" issues that keep coming up again and again. Like Telangana, Amarnath Yatra, state border disputes and more. Not much interest will be left by now, for those folks. So this is for only those who have a stake in Kaveri water or those who want a peaceful south India in the long run. I am in no way an expert in this topic, but since I drink Kaveri water every day, I have special interest in learning more from my readers here. For that I will present what I have understood about the topic and seek your comments and/or corrections.

Map of the River:

Kaveri is born at Talakaveri in south Western mountains of Karnataka. After Talakaveri, you will find a long list of sacred places and temple towns all through its 765 KM flow towards south East, where it merges with Bay of Bengal. Out of this trek, 320 KM is in Karnataka and 416 is in Tamil Nadu. Some of the places are, Bhagamandala, Kushalnagar, Srirangapartna and T Narasipura in Karnataka. Then Mettur, Bhavani-Thirunana, Erode, Kodumudi, Karur, Tiruchirappalli/Srirangam, Thiruvaiyaru, Swamimalai, Kumbha konam, Mayavaram and Poompuhar in Tamil Nadu.

There are many tributaties of Kaveri like Hemavati, Shimsha, Arkavathy (now dry), Kabini, Bhavani, Noyyal and Amaravati. The majestic Shivanasamudra falls and Hogenikal falls are very famous tourist destination getting lakhs of people each year.

Dams and sizes:

Kaveri may be a small river among the 7 giant rivers of India mentioned above (with Saraswati dry now), but it does have many dams.

KRS Dam, Karnataka. {Source: InMysore}

But the two key dams to note are Krishna Raja Sagar dam in Mandya district of Karnataka and Mettur dam in Salem district of Tamil Nadu.

KRS dam, built in 1924, is 125 feet tall, 3 KM in length and can store a max capacity of 49 TMC of water. 

Mettur Dam, Tamil Nadu. {Source: Wikipedia}

Mettur dam, built in 1934, is 120 feet tall, 1.7 KM in length and can store a max capacity of 93.4 TMC of water.

Leaving aside dead storage capacity, you can assume that KRS dam can hold about 44 TMC of water and Mettur can hold about 88 TMC of water. So approximately, Mettur can hold twice as much water as KRS dam. Incidentally, KRS was built entirely by the great engineer Bharat Ratna, Sir M. Vishveshwaraiah and I have heard that he gave the design for Mettur dam too. One thing is in common. both are very vital dams and both are very old. One other important thing to note, all dams in Karnataka together can hold only around 10% of the annual water flow in Kaveri that is in excess of 725 TMC.


Agreements:

Kaveri water sharing discussions and disputes go back over 200 years. Right from the beginning of 19th century, there are discussions involving the Mysore independent princely state (now part of Karnataka) and Madras British Presidency (now Tamil Nadu). The two key agreements to note are from 1892 and 1924. There were other minor agreements too. While Karnataka kept asking right after independence to repeal these British era agreements and form new one, Tamil Nadu insisted on the same, as there was a huge advantage for it to keep them. So everything boiled down to 1991 tribunal interim order and 2007 final order from Indian government.

Details of Kaveri water sources, usage area and contentions. {Source: Wikipedia}

The table in the image above (click on it for a bigger display) shows the basin area, drought area, sources of water per each state's arguments, quantity sought by each state and what is currently in vogue per the 2007 Kaveri Water Tribunal verdict. The numbers are complex, and contentious. Lots of court paperwork exists for those who want to research further. If you see one of the rows showing the demand of states involved, the total quantity of water will be 157% of what is available during an average year. So it is impossible, to give what the states are asking, as the demand is too higher than supply.

But at a higher level, approximately, 30% of the water river sources are in Tamil Nadu and 53% are in Karnataka. Also, approximately 54% of the river basin area is in Tamil Nadu and 42% is in Karnataka. And finally, the Government of India appointed (chaired by the Prime Minister of India) and monitored tribunal says 58% of the water should be used by Tamil Nadu and 37% by Karnataka. To keep matters simple, I am not getting into Pudhucherry and Kerala's matters which involve the final 5% of water usage.

In reality, the core contention between the states is the source, usage and times of usage of water.

Crop and Rain Patterns:

Paddy cultivation in Kaveri delta. {Source: Indiawaterportal}

Paddy, Sugarcane, Ragi and Jowar are the four major crops grown along Kaveri river basin. Out of these, Mandya district of Karnataka and Tanjavur, Pudukottai, Tiruchirapalli and Kadalur districts of Tamil Nadu grow the most water intensive Paddy. Kadalur in TN is also growing the most sugar cane, another highly water intensive crop.

Domestic Water Consumption from Kaveri. {Source: Indiawaterportal}

When it comes to drinking water projects using Kaveri, it is mostly in Karnataka. As you can see in the image here showing water consumtion at urban local bodies, Bengaluru has a skyscraper literally. Many other towns and cities across south Karnataka depend heavily or solely on Kaveri for drinking water of urban population.

For those seriously interested in learning more about Kaveri delta's crop patterns, please refer to India Water Portal for a wealth of information.

In Karnataka, Mandya is the most blessed district as it grows very high quality crops using Kaveri. In Tamil Nadu, coastal Kaveri delta grows 3 crops in Kaveri delta. Jun-Sep Kuruvai, July-Jan Samba paddy and Oct-Feb Taladi. Kaveri delta farmers of Karnataka get rain only from SW Monsoon (Jun-Sep). TN Kaveri farmers get both SW and NE Monsoons (NE starts in Oct).

Main complaints from Karnataka:

1) Disproportionate Usage by Tamil Nadu: While only 30% or so water sources of Kaveri are from Tamil Nadu, why should it be allowed to use 65 to 70% of water each year, including the water that flows downstream anyway? Both are Indian states, and when Karnataka contributes to 53% of water to the river, restricting it to use only 37% or less of water is unjust.

2) Distress formula, drinking water and North East Monsoon: This is a major problem with Kaveri water sharing agreements and tribunals. There's NO practical formula when rains fail. For instance, in the year 2012, nearly half of rains have failed. During such years, distress has to be equally shared between the states. The Prime Minister, who heads the tribunal should not force monthly water to be released per regular year computations, when there is half rain as a regular year. What Karnataka farmers say, there's usually more water in early October in TN reservoirs than Karnataka (56 TMC in TN as of Oct 3rd, 2012, while around 46 TMC in KA). And it rains 2 to 3 more months in TN still. Why should central government side against Karnataka to dry the dams in October in such condition? Once water is left, it does not climb up gravitational pull to a upper riparian state. Some even quote UN A/HRC/RES/18/1 Human Rights clause to say that drinking water in Karnataka should be a higher priority than 2nd or 3rd crop being grown in Tamil Nadu, when water is scarce.

3) TN is a bullying neighbour, right from British era: Just today in the newspapers, an expert L Sandesh wrote Cauvery row: 200 years of oppression by Tamil Nadu. There are books, papers, documentaries and countless such arguments that Karnataka (and Mysore before) is made to suffer due to a lopsided British agreement which was heavily against the interests of Karnataka all along. Worse, terrorists like LTTE and smugglers/killers like Veerappan have bullied the state in an undemocratic way. Another point that keeps coming up in news papers is that since Tamil Nadu has India's largest number of registered regional parties, it has a bigger political muscle to use in Dilli against Karnataka, in the era of coalition politics.

4) Not allowed to expand or build new dams: This is also a common complaint. Karnataka has not been allowed to build/enhance any Kaveri dam for decades. Any irrigation or drinking water project, usually sees a court battle from TN. When the population of Bengaluru doubled in the past 20 years, the number of farmers needing water in 4 to 5 districts is very high, more water should be made available to the state that contributes over half of Kaveri water, is their argument.


5) Cultivated area mismatch: This goes hand in hand some of the above ones. There is no definite per district cultivated land area as the numbers keep varying. But at a high level, it is safe to assume that Tamil Nadu cultivates 2.5 to 3 times the area that Karnataka cutivates using Kaveri water. Some of this addition in TN was done in violation of the 1924 agreement that was in vogue till 1974, where max limits were proposed to both states. That is the argument of Karnataka farmers.

6) Water wasted at Bay of Bengal: In spite of all this heavy fight for TMC by TMC of water, lots of water gets wasted into the sea at TN. Why can't it be used more productively, instead of snatching more from Karnataka?

Main complaints from Tamil Nadu:

1) Violation of Supreme Court orders: This is the most popular phrase in any Tamil Nadu politics. Karnataka is a bad state that violates supreme court orders. Details are provided to show how crops are standing and Karnataka is storing water in the dams, but not releasing as per court orders or Tribunal orders. Note that there is a frequent plea to gazette the tribunal order and also to strictly monitor monthly release of water from Karnataka.

2) Violence and Disruption: In 1991, when the interim order of Kaveri tribunal came through, which was strongly opposed in Karnataka, riots broke out. 18 people were killed in this primarily anti Tamil Nadu riots. Small scale reprisals happened in TN too, but this terrible period under Congress government in Karnataka, is often cited as how intolerant and violent Karnataka people can get, when it comes to river water sharing. Also, since the most active national highway in southern India, NH-4 from Mumbai to Chennai, passes through Karnataka for a big 500+ KM distance, lots of vehicle movement disruption and damage happened in the past.

3) Manage your water sources better: Why punish TN farmers when Karnataka fails to take care of its irrigation and drinking water projects better? Clean up the lakes, revive other rivers, but don't reduce Kaveri water that is the lifeline of millions of farmers in TN Kaveri delta.

4) Karnataka gets more rain and has more water sources: Annual rainfall in Karnataka is 1248 mm.Tamil Nadu receives less than 1000 mm of rain on an average. Why not use other rivers in Karnataka and let Kaveri be used by mostly Tamil Nadu as it is done for 1000s of years? There are no major water sources other than Kaveri for central and coastal TN.

5) Insensitive neighbour: Karnataka does not care for Tamil Nadu people. By blocking Kaveri river, which is "our" right, it is turning the fertile arable land into desert. In here, you can see lots of videos and propaganda material showing that Karnataka is a bad neighbour. Listen to some of the speeches of politicians.

6) Can't Trust Karnataka and Wait till January: When KRS and other smaller Karnataka dams are close to being full in September, even though there is water in Mettur dam in TN, we can't trust Karnataka to hold our share of water till December or January, when crops need this water. That's why we need water to be released monthly.


Solutions? 

Before getting into solutions, the most important ground realities to note are :-

• Kaveri is a sacred river for all those who use it directly or indirectly.
• Kaveri water has to be shared by all those who have a stake at it. This is for today, 10 years from now and even 500 years from now. 
• There is NOT enough water in Kaveri already, to support the drinking water needs of over 2 crore people and the irrigation needs of 81,000 sq KM area. Compared to bigger rivers, 700-800 TMC total water availability here is low.
• Only rivers connected to Kaveri area must be considered in computations and arguments. For instance west flowing rivers in coastal Karnataka get lots of rain, but can't be of any use to Mandya farmers or Bengaluru homes. Similarly, water sources in Tamil Nadu dependent on Kerala or Andhra Pradesh can't be discussed in this matter, as they serve other areas of the state.
• No matter what politicians and other "my state only" organizations say, Kaveri river is NOT any one state's property. It has to be shared. Shared today, tomorrow and for ever. There is an entire generation of politicians on both sides, who have grown up doing "my state should get everything, you can go to hell" politics. That attitude does not help solve the vexed issue.
• Since both Karnataka and Tamil Nadu are progressive states that are doing very well in the Indian context, a peaceful co-existence is a must. For that water is a very essential source which can't lead to tension and legal/street battles.

Now that we know some ground principles of peaceful co-existence, let's look into what can be done:

1) Conserve Water: There are 100s of ways both urban and rural population can conserve water. You can be assured that as years progress, as population grows in both states, there will be lesser and lesser Kaveri water available. Check out some ideas like these. Also, drip irrigation for paddy is a novel option to explore.

2) Rain water harvesting: I am glad that Bengaluru corporation is not going to give building plan approvals now, if the new homes/buildings being constructed don't have rain water harvesting. Even existing houses can implement this as this video shows in simple terms.

3) Removing silt from dams: Across both states, massive effort must be done to remove silt from dams. When there is capacity for x TMC, fill the dams fully when the rains come, so that those 4 to 6 TMC missed out per dam will make a big impact during dry months.

4) Reviving smaller rivers: One river that comes to mind easily is Arkavathy river west of Bengaluru city. When I was a kid, I used to drink waters of Arkavathy river supplied from Tippagondana Halli reservoir. Now the river is dead. Revival plans are hearty to note. Such small effort will go a long way in reducing dependency on only Kaveri. Tamil Nadu could start with Noyyal river revival immediately which is polluted heavily and hard to use. Both states should revive every possible river as every TMC of water counts!

5) Reviving lakes: Tamil Nadu for instance had 40000 lakes in the year 1960. By the year 2000, it had lost 10,000 lakes! That's a huge number of lakes lost to pollution, industrial waste and encroachment. There should be a war like attempt by NGOs, common people and governments to revive the life sustaining lakes. One such fantastic effort is happening now in Karnataka, at the Puttenahalli lake area. Everyone knows that 100s of lakes around Bengaluru got gobbled by real state. Revive them. Again, every drop counts!


6) Preventing precious river water wasted into sea: I personally don't know what percentage of Kaveri water goes into sea unused, but going by the comparisons I have seen for Krishna river, it must be high. Use every drop of this precious river's water. 100s of TMC of water can be added to use by practical use of every drop of water.

7) Growing less water intensive crops: As you have noted from the crops section above, massive amount of water intensive paddy and sugar cane are grown by Kaveri delta farmers. Anywhere from 55 to 70% of the total crops grown could be paddy. Keep in mind, Tamil Nadu has access to only 3% of the water in India. Karnataka has the 2nd largest amount of dry land in India after Rajasthan. Why grow so much paddy which requires lots of water? Switch to less water intensive, but good nutritious millets. Or switch to paddy varieties that use half the water per KG (from 5000 liters to 2500 liters) like S Anand, a farmer from Huthenahalli, Chikkajala, demonstrated. Since majority of Kaveri water is used for agriculture and that too for paddy, this solution alone can save lots of water and save both states!

8) Distress formula: Share the hit of nature equally: If the rains are down by 30%, both states should take a hit of 30% water for that month or season. Be good neighbours during tougher times. Every 10 years or so, there is a massive drought in Kaveri area. 1991, 2002 and now 2012 are examples. Don't fight it all the way till Supreme Court as it only worsens the relations. CMs should sit down and agree on a reduced water sharing and crop cultivation for that year. The central government should not be partial to either of the states due to coalition compulsions. Both are Indian states, and the PM can't favour one state over another. Blame games are not going to help anyone. A farmer without water for crops or a house without drinking water is going to suffer no matter in which state.

9) Understand the 21st century's needs of both states, not 19th or 20th century demands: Yes, before the age of Mettur or KRS dams, majority of the water was available for Tanjavur & nearby areas for crops. So obviously generations of farmers depended solely upon that. But now things have changed. There's Mandya irrigated heavily. There is a very fast growing Bengaluru city that needs more water than ever before. There are districts long before Tanjavur or Kadalur in both states that have started irrigating from Kaveri. There is Hogenikal kind of new drinking water projects in TN. Tamil Nadu insisting on 2/3rd or more of water, while Karnataka insisting on half of Kaveri water is just not working out. It's a small river again, for the crores of population it supports. Sit and decide how to handle around 725 TMC of total annual water available, in the best possible way. No one is a victim, no one is a villain, if farmers talk to each other directly. After all every farmer and every user of Kaveri water is an Indian.

10) Think of other give and take policies: For instance Karnataka buys water from Maharashtra, the upper riparian state, during dry season by paying certain amount of crores per TMC. In 2004, Karnataka paid 3.3 crores Rupees to Maharashtra to buy 2 TMC of water in adverse conditions. Maybe power in return for water during hard times, or a share in agricultural crop yield for water. Think outside the box. I have repeated enough that there is not enough water for everyone's demand, so innovative approaches need to be developed.

If you read it all the way till here, I hope you really got some clarity on what the issue is, why it keeps popping up so often, and what are the possible ways we can think positively and resolve the issues. After all, Indians sharing water with Indians, Indians not bullying Indians and Indians living peacefully with other Indians will not be disliked by anyone..except the generation of politicians or street organizations that have thrived using this conflict.

Thanks to my online friends who raised some of these points during discussions and also gave some ideas.

Do drop in your comments, corrections, and ideas. I am by no means an expert in this area, so I am always willing to learn from the knowledgable. All I wish is peace.. Shantih!
