Sylvan Lake is in the White River National Forest approximately 10 miles south of Eagle, Colorado. This high hazard class dam was originally constructed in the 1930’s without formal design or construction quality control. In recent years, dam safety inspections determined the dam was not capable of safely passing a probable maximum precipitation (PMP) event and was ordered by the State of Colorado to be reconstructed.

In 2018, construction began on a new dam comprised of earth fill, sand filter, and roller compacted concrete (RCC) downstream facing and spillway. During construction, concrete durability was evaluated due to premature exposure to severe freezing temperatures, sinkholes and leakage under the former dam embankment were identified.
