Despite the good spells of rain, the storage in the hydel reservoirs in the State continues to cause concern.
Official sources told The Hindu here that the State received more rainfall during the first week of November when compared to the previous year, and all the four regions, except north interior Karnataka, received excess rain during this period.
However, the levels in Supa and Varahi reservoirs decreased slightly and it was only in Linganamakki that there had been a slight increase in the level in the first week of November.
However, the level in all the three reservoirs was low compared to the corresponding period last year.
The level in the Linganamakki reservoir, which stood at 1,813.45 ft. (FRL 1,819 ft.), was more by 5.58 ft. compared to the last 10 years' average, but lower by 2.15 ft. compared to the previous year's level of 1,815.60 ft. during the same period.
The level in the Supa reservoir, which was 1,799.15 ft. (FRL 1,859.39 ft.) was lower by 1.01 ft. compared to the last 10 years' average and also lower by 1.71 ft compared to the corresponding level last year.
The level of Varahi reservoir, which stood at 1,927.66 ft. (FRL 1,950 ft.), was down by 5.38 ft. compared to the last 10 years' average and also lower by 4.92 ft. compared to the figure during the corresponding period last year.
The sources pointed out that the State would have to depend more on thermal and other sources of power generation and seek a greater share from the central grid to bridge the demand-supply gap in the State.
In Linganamakki reservoir as against the FRL of 151.75 ft., the storage was only 133.716 ft.
