About Ayad River
- The Ayad River is also known as the Ahar River.
- Origin: The Ayad River originates in the Gogunda Hills in north-west Udaipur district of Rajasthan.
- Course: The river flows through Udaipur city, receives the outflow of Lake Pichola and Fateh Sagar Lake, feeds Udaisagar Lake, and later joins the Berach River.
- Nature: The Ayad River is a seasonal river, and its basin receives about 90% of its annual rainfall from the southwest monsoon between July and mid-October.
- Tributary of: The Ayad River is a tributary of the Berach River, which drains into the Banas River, then the Chambal River, followed by the Yamuna River, the principal tributary of the Ganga River.
- Archaeological Value: The river is associated with the Ahar-Banas Chalcolithic (Copper-Stone Age) culture, which dates from 3000 BC to 1500 BC.
- Historical Monuments: The riverbank contains the Ahar ki Chhatriya, which are the royal cenotaphs (memorials) of the Maharanas of Mewar.
- Threats: The Ayad River is heavily polluted by solid waste and sewage, while concretization of its floodplains, riverbanks, and riverbed edges has reduced its carrying capacity, restricted groundwater recharge, and threatened the ecological integrity of Udaisagar Lake.
