Nethravathi

The Nethravathi River is a significant river in the Dakshina Kannada district of Karnataka, India. It originates in the Western Ghats at an elevation of about 3,000 feet. The river flows westward for approximately 120 kilometers before merging with the Arabian Sea near Mangalore. It is a crucial source of water for irrigation and drinking water for the region.

The Nethravathi River basin covers an area of approximately 2,200 square kilometers. The river is fed by monsoon rains and several tributaries, contributing to its substantial water flow. The fertile plains along its banks are extensively used for agriculture, with crops like paddy, areca nut, and coconut being cultivated.

The river plays a vital role in the ecosystem of the coastal region. Its estuary in Mangalore is a biodiversity hotspot, supporting a variety of marine and estuarine life. The river also supports local fisheries, contributing to the livelihoods of many communities.

Efforts have been made to manage the water resources of the Nethravathi River, including the construction of dams and reservoirs for water supply and power generation. However, challenges such as sand mining and pollution from industrial and agricultural runoff can impact its water quality and the health of its ecosystem. The Nethravathi River remains a lifeline for the people and environment of Dakshina Kannada.
