Prebble, located in Cedaredge, Colorado, is a privately owned dam constructed in 1960 for irrigation purposes on Youngs Creek. Standing at a height of 19 feet and with a storage capacity of 310 acre-feet, Prebble primarily serves agricultural needs in the region. The dam, made of earth and stone core types with a soil foundation, spans 600 feet in length and covers a surface area of 26 acres.

With a low hazard potential and a satisfactory condition assessment as of the last inspection in October 2016, Prebble plays a crucial role in water resource management in Delta County, Colorado. Despite its age, the dam continues to operate efficiently, with a maximum discharge capacity of 441 cubic feet per second. Although the dam does not have a spillway, it is equipped with slide gates and uncontrolled outlets to regulate water flow.

While Prebble currently meets safety guidelines and has a risk assessment rating of 2 (considered high), ongoing monitoring and maintenance are crucial to ensure the continued reliability of this essential water infrastructure. As climate change impacts water resources, dams like Prebble will be vital in sustaining agricultural activities and supporting local communities in the face of evolving environmental challenges.
