Dravida Munnetra Kazhagam (DMK) MP P. Wilson accused the Congress of ignoring Tamil Nadu’s water woes and led a walk‑out in both the Rajya Sabha and Lok Sabha over the denied Cauvery allocation. The state has yet to receive any of the 42 TMC promised for 2026, prompting a Supreme Court petition.

Key Takeaways

  • DMK MPs walked out of both houses demanding Cauvery water allocation
  • Tamil Nadu has received zero of the 42 TMC promised for 2026
  • MP P. Wilson blamed the Congress for sidelining the issue

During the Monsoon Session on August 3, 2026, Dravida Munnetra Kazhagam (DMK) Rajya Sabha MP P. Wilson staged a walk‑out in both the Rajya Sabha and Lok Sabha, protesting the state’s exclusion from its entitled share of Cauvery water. The Cauvery Water Management Authority (CWMA) mandates 9.9 TMC in June and 32 TMC in July, totaling 42 TMC, yet Tamil Nadu has not received a single drop this year.

Wilson denounced the Congress, saying it “doesn’t care about Tamil Nadu’s problems” and is focused on other national issues. He urged the Parliament to debate and pass a resolution compelling the Union government to honor the water allocation.

Historical Background

The Cauvery dispute dates back to the 19th century, intensifying after the 2007 formation of the Cauvery Water Management Authority. Despite multiple Supreme Court judgments allocating 42 TMC annually to Tamil Nadu, implementation has been inconsistent, leading to recurring tension between Tamil Nadu and Karnataka.

Why This Matters

BozokMedia analysis shows that the water shortfall threatens agricultural output, groundwater recharge, and rural livelihoods across Tamil Nadu. Without a reliable supply, the state’s economy and social stability face heightened risk.

"Equitable distribution of Cauvery water is essential not just for water security but also for regional peace," says water‑policy expert Dr. Raman Singh.
Did You Know?: The Cauvery River’s total annual flow is roughly 740 TMC, making it one of India’s most contested river basins.
