The Ukai Dam, constructed across the Tapti River, is the second largest reservoir in Gujarat after the Sardar Sarovar. It is also known as Vallabh Sagar. Constructed in 1972, the dam is meant for irrigation, power generation and flood control. Having a catchment area of about 62,225 km2 and a water spread of about 52,000 hectares, its capacity is almost the same as that of the Bhakra Nangal Dam. The site is located 94 km from Surat.
The dam is an earth-cum-masonry dam. Its embankment wall is 4,927 m long. Its earth dam is 105.156 meters high, whereas the masonry dam is 68.68 meters high. The dam's left bank canal feeds water to an area of 1,522 km2 and its right canal to 2,275 km2.[1]
Vajpur fort, built by the Gaekwad dynasty of Baroda, was submerged in the reservoir. It can be spotted when water level in the reservoir is low.[2]
