Renuka lake is in the Sirmaur district of Himachal Pradesh in India and it is 672 m above the sea level.

According to local tradition, after the death of Jamadagni after he refused to part with the divine cow, Kamadhenu, Renuka is regarded to have jumped into the lake to take her own life.

One day advance, on dashami, the palanquin of Parashurama is brought to Renuka from the ancient temple in Jamu Koti village in a traditional procession known a ‘Shobha Yatra’, attended by lakhs of devotees.

The main cause of this is the soil being deposited on the banks, with the rain water and landslides in the nearby mountains.

Also the waste of construction material is being dumped into the lake for years, which is a big threat to the environment.
