Basava Sagar Dam, previously known as Narayanpur Dam, is a dam constructed across the Krishna River at Siddapur Village in Muddebihal Taluk, Bijapur District, Karnataka, India. The reservoir that it impounds is known as Basava Sagar, and has a total storage capacity of 37.965 tmcft (1.075 km³), with 30.5 tmcft (0.85 km³) 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 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.
In April 2011, farmers fearing loss of their crops staged a protest at Narayanpur dam, and forced the staff to release water after officials had shut down releases due to low rainfall and inflows. This type of protests in earlier years, such as the one in April 2005 where large numbers of police prevented the farmer's from releasing the water.As of August 2013, the project has an estimated capacity of 31.47 TMC.
