The Adyar River is a prominent river in the Indian state of Tamil Nadu, flowing through the city of Chennai. It originates from the Nandambakkam area and travels approximately 42 kilometers before emptying into the Bay of Bengal. The river plays a crucial role in the local ecosystem and supports various flora and fauna along its banks. Historically, the Adyar River has been significant for irrigation and transportation. However, urbanization and pollution have impacted its health over the years. Efforts are ongoing to restore the river's natural environment and improve water quality, benefiting both the community and wildlife.
