Shivamogga: Continuous heavy rains across Shivamogga have caused the Tunga River to overflow, breaching the danger level on Tuesday. The relentless downpour in Agumbe and Thirthahalli areas has increased the inflow of water to the Tunga dam. With the dam already at its highest capacity, the excess water is being steadily released into the river, resulting in a significant rise in the water level.
