The Tungabhadra dam at Hosapete has been getting good inflow owing to continuous rains in the catchment areas for the past one week and it has raised the hopes of farmers about an early release of water into the canals and getting a good kharif yield.

On Saturday, the inflow into the dam was around 76,527 cusecs taking the reservoir level to 1,622.75 feet, just short of the full reservoir level of 1,633 feet.

Presently the dam has augmented 66.07 tmcft.

A study of the performance of the reservoir for the past 28 years revealed that good inflow was noted during the first fortnight of July for about eight years.

During the past 28 years, the reservoir had not filled up for seven years (1995-96, 2001-02, 2002-03 and 2003-04, 2015-16, 2016-17 and 2017-18). During these years, farmers, however managed to get kharif crop with great difficulty.

In the past 28 years, maximum water utilised for kharif crop (upto November 30) was 112.098 tmcft during 1993-94 and minimum of 66.800 tmcft in 2017-18.

K. Govindulu, former Superintendent Engineer, Tungabhadra Dam, was of the view that with the current storage in the dam, water can be released in all the canals, Left Bank Main Canal, Right Bank Low-level and High Level canals and also in the ancient Raya and Basava canals, simultaneously to enable commencement of agricultural operations early.

“The Irrigation Consultative Committee (ICC), which is scheduled to meet on Monday (June 16th) can take a decision to release water into all the canals immediately which was advantageous to the farmers in the command area. For, 66 tmcft of water is in store and even if the discharge is at the rate of 9,000 cusecs per day, through all the canals, it will suffice up to October 10th (84 days) and also anticipate good inflow meanwhile, with reports of continued good rainfall in the catchment areas”, he told The Hindu, adding “This year, the situation is very encouraging and assures of adequate water for irrigation”.
