Tungabhadra Dam

 

The Tungabhadra Dam is constructed (near the town of Hospet in Karnataka)across the Tungabhadra River, a tributary of the Krishna River

The dam creates the biggest reservoir on the Tungabhadra River  with 101 tmcft of gross storage capacity at full reservoir level (FRL) 498 m MSL, and a water spread area of 378 square kilometres

The dam is 49.39 meters high above its deepest foundation.

 The left canals emanating from the reservoir supplies water for irrigation entirely in Karnataka state. 

Two right bank canals are constructed — one at low level and the other at high level serving irrigation in Karnataka and Rayalaseema Region of Andhra Pradesh

The identified water use from the project is 220 tmcft by the Krishna Water Disputes Tribunal  Karnataka and Andhra Pradesh got 151 tmcft and 79 tmcft water use entitlement respectively.

Krishna Water Disputes Tribunal (KWDT) is a tribunal set up by the government of India in 1969 under the Interstate River Water Disputes Act of 1956 to resolve the disputes between the states of Karnataka,Maharashtra,Telangana and Andhra Pradesh over sharing of Krishna River water.

The KWDT I was headed by R. S Bachawat, a former judge of the Supreme Court.

The Krishna River is the second biggest river in peninsular India which originates near Mahabaleshwar in Maharashtra from the statue of a cow in a temple.

It then runs for a distance of 303 km in Maharashtra, 480 km through the breadth of North Karnataka and the rest of its 1300 km journey in Telangana and Andhra Pradesh  before it empties into the Bay of Bengal

The river basin is 257,000 km2 and the States of Maharashtra, Karnataka and Andhra Pradesh contributes 68,800 km2 (26.8%), 112,600 km2 (43.8%) and 75,600 km2 (29.4%) respectively




Krishna Water Disputes Tribunal (KWDT)Award

The Bachawat commission (KWDT I) went over the matter in detail and gave its final award in 1973.

While the Tribunal had in its earlier report detailed two schemes, Scheme A and Scheme B, the final award only included Scheme A and Scheme B was left out. Scheme A pertained to the division of the available waters based on 75% dependability, while Scheme B recommended ways to share the surplus waters.

The government took another three years to publish the award in its Extraordinary Gazette dated 31 May 1976. With that the final award (Scheme A) of the KWDT became binding on the three states.

The KWDT in its award outlined the exact share of each state.

The award contended based on 75% dependability that the total quantum of water available for distribution was 2060TMC This was divided between the three states in the following manner.


Maharashtra 560 TMC
Karnataka 700 TMC
Andhra Pradesh 800 TMC

In addition to the above, the states were allowed to use regeneration/return flows to the extent of 25, 34 and 11 TMC respectively subject to time bound usage of allocated water out of 2060 TMC total allocation as stated in clause V of the KWDT-1 final order.
