The Haranagi Reservoir
The river is mostly known for the Haranagi reservoir. This is a masonry dam built across the river on the Mysore-Kodagu border and depends on the South-West monsoon to fill up its gross storage capacity of 8.5 tmcft water. The water from the reservoir irrigates 1.50 acres of land across Mysore and Hassan.
