According to Shiva Purana, sage Gautama, who is the son of Lord Brahma, had performed severe meditation for Lord Varuna on the Mountain Brahmagiri since there was severe drought in that area.
Lord Varuna, the great ocean god, and the reliever of sins of the people, had appeared before Gautama and asked him to pray to Lord Shiva to fulfill his wishes.
Due to that, the great rishi Gautama started doing severe penance on Lord Shiva. Lord Shiva appears before him, and sends Ganga into the earth and she has transformed into the holy River Godavari and began to flow in the earth.
Due to the request of Mata Godavari, Shiva appears as Tryambakeshwara, one of the twelve Jyotirlingas. Gautama and several other sages took bath in the divine river. Tryambakeshwara temple is a famous temple for getting relieved from Pitru doshams and people from all parts of India visits this temple.
Let us worship Mata Godavari and be blessed.
