| Cucharas #5 Dam | 2019 | Huerfano County | Cucharas River | This 1910 irrigation dam experienced structural problems throughout its life, including a partial failure in 1987 which resulted in the emergency dynamiting of a spillway. Reconstruction of the dam was proposed in the 2010s but was deemed economically infeasible. Following years of litigation, the State Engineer took emergency control of the dam in 2017 for safety reasons. The state removed it in 2019, recovering the cost in court from the dam's owners.[3] At the time, it was the third-largest dam ever to be removed in the United States.[4] | |||
