Trial Lake is a popular destination in the Uinta Mountains of Utah. It was named after a party of explorers who camped there in 1876. The lake is fed by snowmelt and several small streams, and is part of the upper Provo River system. Its watershed receives over 15 feet of snow annually, providing a significant contribution to the Provo River’s overall flow. Trial Lake also serves as a recreational hub, with hiking, fishing, and camping being popular activities. The surrounding area is also used for cattle grazing. Additionally, Trial Lake serves as a valuable source of water for irrigation and other agricultural uses downstream.
