The Palar River is a significant river in southern India, primarily flowing through the states of Tamil Nadu and Karnataka. It originates from the Nandi Hills near Bangalore and travels approximately 250 kilometers before emptying into the Bay of Bengal. The river plays a crucial role in irrigation and supports agriculture in the surrounding regions. The Palar River basin is characterized by a semi-arid climate, which affects its water flow, especially during the dry season. Despite its importance, the river faces challenges such as pollution and reduced water levels due to over-extraction and urbanization. Conservation efforts are essential to maintain its ecological balance.
