Trio, located in Delta, Colorado, is a private dam designed by the USDA NRCS for irrigation purposes. Completed in 1955, this earth dam stands at 30 feet high with a length of 325 feet, providing a storage capacity of 232 acre-feet. The dam serves multiple purposes including fire protection, stock watering, small fish ponds, irrigation, and recreation, making it a vital resource for the local community.

With a low hazard potential but an unsatisfactory condition assessment as of 2014, Trio is regulated and inspected by the Colorado Department of Water Resources. Despite its high risk assessment rating, the dam has no spillway and relies on slide gates for outlet control. The surrounding area is at risk of inundation, highlighting the importance of proper risk management measures and emergency preparedness for this critical water resource.

Trio's location on the Surface Creek-TR river and its proximity to the city of Cedaredge underscore its significance in water resource management and climate resilience efforts in Colorado. As water resource and climate enthusiasts, it is essential to monitor and support the maintenance and safety of dams like Trio to ensure sustainable water management and protection of communities against potential risks and emergencies.
