Trout Lake, located in Hinsdale, Colorado, is a privately owned reservoir primarily utilized for irrigation purposes. Constructed in 1931, this earth dam stands at a height of 15 feet and spans a length of 280 feet. With a maximum storage capacity of 338 acre-feet and a normal storage of 198 acre-feet, Trout Lake covers a surface area of 28 acres and is fed by West Trout Creek.

Despite its low hazard potential, Trout Lake is categorized as having a high risk assessment due to its condition being assessed as fair in 2019. The dam is subject to state regulation, with the Colorado Division of Water Resources overseeing permitting, inspection, and enforcement. The lack of a spillway and associated structures may pose challenges in managing potential overflows and maximizing discharge. It is important for water resource and climate enthusiasts to monitor Trout Lake's risk management measures and stay updated on its condition assessment to ensure the safety and sustainability of this vital water resource.
