Srisailam Dam Gates Stay Shut Amid Severe Monsoon Inflow Deficit
The Srisailam reservoir has not received enough rainwater this monsoon.
Its gates usually open several times by the middle of August, but they remain closed.
The reservoir contains only 41.51 TMC ft of water, compared with space for 215.81 TMC ft.
Last year at the same time, it held 209.16 TMC ft.
Kurnool and areas upstream in Karnataka and Maharashtra have received much less rain than usual.
This has reduced water flowing through the Krishna and Tungabhadra rivers.
Other nearby reservoirs are also holding much less water than their full capacities.
Officials say more rain is needed to protect farming, drinking-water supplies, and electricity generation.
Srisailam reservoir gates remain closed into the fourth week of August.
The reservoir holds 41.51 TMC ft against a 215.81 TMC ft capacity.
Water levels are 820.90 feet, well below the 885-foot full level.
Kurnool received under 30 mm of rain since July 1, versus 117.23 mm normally.
Officials warn of strains on agriculture, drinking water, and hydropower without renewed monsoon rainfall.
