Uncertain & Inefficient Mode of Operation 

There is no established mode of reservoir operation to sluice the silt, and the recommended mechanism of lower draw down, longer sluicing period, and higher escapages will make the dam act more like a barrage, apart from wasting precious stored water.

In any case, the stored water in the reservoir will have to be emptied each year for the removal of the silt in May, which will be a significant loss of valuable stored water.

And during this process of emptying, sluicing and refilling (3 months approx.) operation, the power generation would be adversely affected, and would ultimately depend on the normal discharge of the river (after the live storage is exhausted), making the dam generate power on the run-off the river, or thermal systems.
