In the past this was a wonderful source of low cost power. Today we are aware of risks as well. they are: 1) Erratic monsoons make supply inadequate and uncertain. 2) In earthquake prone regions this could make a disaster. 3) As years go by, the debris and mud that settles on the floor can reduce volume of check dams considerably. 4) the construction material of dams can crack in 100 years due to wear and tear causing death and suffering 5) India hasa very poor ytrack record of rehabilitation of poor people evacuated from dam sites following land acquisition.
