In 1872, the town of Aaron, near the mouth of Asay Creek was settled by about 70 people. It was also called Asay, later these families joined others along the Sevier River and founded the old town of Hatchtown, and after severe floods and the breaking of the first reservoir, it was moved to its present site and is known as Hatch.
Services are available year round, and public and private campgrounds are in the area.
