Dams in India
Basava Sagar Dam or Narayanpur Dam is a dam constructed across the Krishna River. Located at Narayanapur in Yadgir district, Karnataka, India, the reservoir that it impounds is known as Basava Sagar, and has a total storage capacity of 37.6 tmcft (1.075 km?), with 30.5 tmcft (0.85 km?) live storage. The full reservoir level is 492.25 m MSL and the minimum draw down level is 481.6 m MSL. It was a single purpose project meant only for irrigation, but downstream electrical generation and drinking water considerations enter into its management. The dam is 29 meters high and over 10 kilometres long, and has 30 gates for water release. It took Rs. 50.48 crore to complete. When it was completed in 1982 it provided water to irrigate 4.21 lakh hectares in Jewargi taluka in Gulbarga district, Shahapur and Shorapur talukas in Yadgir district, Sindagi and Indi talukas in Bijapur district, and Lingsugur and Devadurga talukas in Raichur district. In 1992, two of the irrigation gates partially failed. In 2005, there was a collapse of one of the gates in the dam and up to a lakh cusecs of water was being released before emergency actions were effective. The gate broke open on the morning of 6 October and most of the water flow was stopped by the afternoon of the 9th. Basava Sagar reservoir dropped several metres as a result.
