Explanation:

Deoria Tal (also Devaria' or 'Deoriya) is a lake about 3 km (1.9 mi) from the villages of Mastura and Sari on the Ukhimath-Chopta road in Uttarakhand. At an altitude of 2,438 meters (7,999 ft), it has heavily wooded, lush green surroundings with snow-covered mountains (Chaukhamba is one of them) in the backdrop. 

Hindu faith states that the Devas bathed in this lake, hence the name. The lake is also believed to be the "Indra Sarovar" referred to in the Puranas by wandering Hindu mendicants, Sadhus. It is also believed that it was the place from where the mighty Pandavas were asked queries by Yaksha. According to the locals it was also said that this lake was built by Bheem, who was strongest among the Pandavas, to appease his thirst, and Yudhister, who was the wisest, suggested Bheem to build his own lake.
