Ukai Dam Tapi: Vallabh Sagar Reservoir, Gates & Travel Guide

Ukai Dam, officially designated as the Vallabh Sagar Reservoir, is a colossal earth-cum-masonry multipurpose dam constructed across the sacred Tapi River in the Tapi district of South Gujarat. Commissioned in 1972 for flood moderation, agricultural irrigation, and hydroelectric power generation, it is Gujarat’s second-largest water reservoir (surpassed only by the Sardar Sarovar Dam on the Narmada) and stands as one of South Gujarat’s most scenic monsoon and winter eco-tourism destinations situated just 90 km east of Surat.

About Ukai Dam & The Vallabh Sagar Reservoir

Engineered to harness the massive monsoon runoff of the Tapi River basin, Ukai Dam boasts an immense catchment area spanning over 62,255 square kilometres. The dam structure itself rises nearly 81 metres high and extends across 4.92 kilometres, backing up a massive inland freshwater sea that covers over 52,000 hectares of water surface surrounded by the green undulating foothills of the Satpura and Sahyadri mountain ranges.

The dam features 22 colossal radial spillway gates capable of discharging millions of gallons of surplus water per second during peak monsoon storms. When water levels reach capacity between August and October, the roaring, thundering cascade of foaming white water rushing into the downstream Tapi canyon creates a hypnotic, awe-inspiring visual spectacle that draws thousands of nature enthusiasts, photographers, and family picnickers from across Gujarat and Maharashtra.
