This fair has a legendary background. Gautam Rishi used to go for a sacred bath in the river Ganga every morning. For him, this had become part of his everday life.
Once, the King of sub Gods (Devtas) - Indra asked Surya (Sun) as to who was the most beautiful woman on the earth. The Sun parried the question and said "Most of people are busy in their work, when I shine during the day and it is very difficult for me to judge as to who is ugly and who is beautiful". Indra asked the same question to Chandradev (Moon God), who said that Ahilya, the wife of Gautam Rishi resding at the confluence of Yamuna and Tamsa was the most beaytiful woman on the earth. Hearing this, Indra was overtaken by evil and lust and made up his mind to aquire Ahilya by hook or crook.
                            
Unbecoming the King of sub Gods, as he was, Indra entered the Ashram (hermitage) of Gautam at midnight and mimicked the call of a cock. Unaware of the wicked designs of Indra, Gautam Rishi set out for bathing in Ganga as usual, mistaking it as dawn. Finding Ahilya alone at home as soon as the sage left, Indra knocked the door and impersonating as Gautam, tried to bluff her. Ahilya was a pious hearted lady. She sensed the evil designs of Indra and cursed him to be a leper with thousand eyes.

Meanwhile, Gautam reached Ganga and entered the holy water for bath. The river Goddess was pleased with the punctuality and devotion of Gautam. She asked him to return home immediately as his wife was in trouble. The Rishi turned back in a hurry, leaving his Kamandal (sacred pot) there. Later, the Goddess Ganga herself returned the Kamandal, filling it with holy water, which was set up in the Ashram in the form of a Sarovar (tank). She also gave a boon that the tank's water will be equal in holiness to the actual Gangajal and those who have a holy dip in the tank will earn the same blessing as one who has a holy dip in the Ganga. Since then, this place, which is about 8 km on Dehradun - Saharanpur Road, is a holy bathing place of religious importance. Thousands of devotees visit the spot in April and October, when a big fair takes place here.
