Description: Thanjavur (Tamil Nadu), July 4, 2025 (ANI): The Grand Anicut (Kallani Dam) recorded a steady inflow of 24,486 cubic feet per second (cusecs) of water, matching an equal outflow, ensuring smooth water distribution across the Cauvery delta system. The total outflow from the dam stands at 24,486 cusecs, distributed precisely among the major irrigation canals and river branches. This release will benefit the ongoing agricultural activities in the delta district. This 1,875 years old dam was built by an ancient Chola king Karikalan around 150 CE, Kallanai stands as one of the world’s oldest water-regulation structures still in use. Situated on the Kaveri River, the dam plays a crucial role in irrigation across Tiruchirapalli and Thanjavur districts. This makes Kallanai one of the oldest functioning water-regulation structures in the world—a remarkable symbol of ancient Tamil engineering and river management.
