Ujjani Dam, Earth-fill dam in Solapur, India

Ujjani Dam is an earth-fill dam across the Bhima River in Maharashtra that holds water for irrigation and power generation. The structure creates a large reservoir where farmers can access water throughout the year for their crops.

Construction of the dam and its canals on both banks began in 1969, with an initial estimate of Rs 400 million; the project was completed in June 1980 at a cost of about Rs 3295.85 million. The Krishna Water Disputes Tribunal award of 1976 allowed Maharashtra to use only 4.753 km3 from the Upper Bhima basin. Commissioned in June 1980, the dam is the terminal and largest dam on the Bhima River.

The dam supports agricultural communities in Solapur district through irrigation systems, enabling farmers to cultivate diverse crops throughout the year.

The dam lies about 8 km upstream of the bridge over the Bhima River on the Pune-Sholapur road, and Pune is 160 km away. The 2,534 m structure is best seen from the banks near Ujjani village in Madha Taluk. The catchment above the dam gets most of its rain between mid-June and mid-September, so flows are highest then.

The reservoir is called Yashwant Sagar, and flamingos winter on it. Its stored water reaches the dam from rivers including Pune's Mula and Mutha, and the reservoir's capacity ranks ahead of Koyna and Jayakwadi. Illegal sand mining in the catchment is a recurring problem.
