Hemavathi

Hemavathi, also spelled Hemavati, is a river in the Indian state of Karnataka. It is a major tributary of the Cauvery (Kaveri) river system and contributes to the Cauvery basin in southern Karnataka.

Originating in the Western Ghats, the Hemavathi drains parts of the Malnad region and Hassan district, flowing generally eastward before joining the Cauvery system. Along its course it supports several irrigation projects and settlements, helping to sustain agricultural and municipal water supplies in the area.

Hydrology and infrastructure are important aspects of the Hemavathi. The river hosts reservoirs and dams used for irrigation and power generation. The Gorur Dam on the Hemavathi creates the Hemavati Reservoir, which supplies water for irrigation and local needs. Another significant dam on the river is the Yagachi Dam near Belur, forming a reservoir that serves irrigation, drinking water, and tourism purposes.

Ecology and economy are closely linked to the Hemavathi. The river’s watershed lies in the biodiverse Western Ghats, with forested slopes that support a variety of flora and fauna. Agriculturally, the river supports crops such as sugarcane and rice in Hassan and neighboring districts. Flow in the Hemavathi is seasonal, rising during the southwest monsoon and diminishing in dry months; dam operations help stabilize water availability for people and crops.

In summary, the Hemavathi is a key western Karnataka river that feeds the Cauvery basin, sustaining irrigation, drinking water, energy, and regional ecosystems across its course.
