Ducks Nest is a privately owned irrigation dam located in Dolores, Colorado, along the Willow Creek-TR. Built in 1917, this earth dam stands at 11 feet high and stretches 1200 feet in length, with a storage capacity of 140 acre-feet. The dam serves multiple purposes including irrigation, fire protection, stock, and small fish pond.

Despite its low hazard potential, Ducks Nest dam has been assessed as unsatisfactory in condition as of May 2006. The spillway is uncontrolled with a width of 40 feet, and the dam is equipped with a single slide (sluice gate) as an outlet gate. The dam's emergency action plan (EAP) status, risk management measures, and inundation maps remain unaddressed, posing a moderate risk level.

Water resource and climate enthusiasts in the region may find Ducks Nest to be a fascinating structure due to its historical significance and multiple usage functions. However, the dam's current condition and lack of updated emergency preparedness raise concerns about its long-term safety and sustainability, highlighting the importance of ongoing monitoring and maintenance efforts to protect both the dam and the surrounding community.
