Dalpat Sagar (lake) is one of the biggest artificial lakes of Jagdalpur that lies on an island. One has to hire a boat in order to reach this 400-year-old lake that was constructed by Dalpat Dev Kakatiya, the king of Warangal region. Boating facilities are also available here, and tourists can enjoy the scenery whilst paddling away in small boats. Many also avail fishing opportunities here that take place in groups during early mornings or late evenings. For nature-lovers, the best time to visit the lake is at sunset when it is lit with an array of hues and presents an ethereal sight. A small lighthouse and a charming musical fountain stationed on the island add to the beauty of the lake.
