By Bharat travel guide
Stretching majestically across the mighty Tapi River in Songadh Taluka of Tapi district, Ukai Dam (creating the colossal Vallabh Sagar Reservoir) is the second-largest multipurpose dam in Gujarat (surpassed only by the Sardar Sarovar Dam). Completed in 1972 as a monumental engineering triumph of modern India, this earth-cum-masonry dam impounds over 612 square kilometers of deep blue waters, providing vital irrigation to 1.5 million hectares of agricultural land, flood protection to the industrial diamond city of Surat, and generating 300 MW of clean hydroelectric power.
With 22 colossal radial crest gates that roar with white spray when floodwaters are discharged during the monsoons, Ukai Dam is one of South Gujarat's most awe-inspiring water marvels. Surrounded by the rolling forested hills of Songadh, the historic 16th-century clifftop fortress of Fort Songadh, and serene boating reservoirs, Ukai provides travelers an exhilarating combination of engineering grandeur and eco-tourism.

Key Attractions & Sightseeing Highlights Around Ukai
- The 22 Radial Crest Gates & Spillway: The centerpiece of Ukai Dam.

- Vallabh Sagar Reservoir Panorama: An inland sea of tranquil deep-blue water extending over 612 sq. km into Maharashtra. The reservoir is dotted with forested islets and fringed by the Satpura hills, attracting pelicans, cormorants, and migratory ducks during winter.
- Hydroelectric Power Station (300 MW): Four giant 75 MW turbines harness the gravitational fall of the Tapi River to generate clean hydroelectric power for Gujarat’s industrial grid.
- Fort Songadh (10 km away): A 16th-century hill fortress rising 1,000 feet above Songadh town, built by the Gaekwads of Baroda (Pilaji Rao Gaekwad). Features stone battlements, ancient water tanks, and panoramic views of the Tapi river plains.
- Dosvada Dam & Forest Eco-Spots: A picturesque historic reservoir situated 15 km from Songadh in the foothills of the Sahyadris, famous for shady teak forest trails and quiet lakeside camping.
