Dreyfus, a privately owned dam located in Cedaredge, Colorado, has been serving its primary purpose of irrigation since its completion in 1961. This Earth-type dam stands at 29 feet tall and stretches 420 feet in length, with a storage capacity of 170 acre-feet. Situated on the Surface Creek-TR river or stream, Dreyfus plays a crucial role in water resource management in Delta County, Colorado, supporting agriculture and ensuring water availability for the surrounding area.

Despite being classified as having a low hazard potential and fair condition assessment, Dreyfus poses a high risk due to its location and the possibility of potential hazards. The dam lacks a spillway and relies on slide gates for outlet control, which may present challenges in managing water flow during peak periods. Inspected every six years, the last assessment was conducted in August 2011, highlighting the need for ongoing monitoring and maintenance to ensure the safety and reliability of this vital water infrastructure.

As climate change continues to impact water resources, dams like Dreyfus play a critical role in mitigating the effects of droughts and floods by storing and regulating water flow. With the state of Colorado permitting and regulating its operations, Dreyfus remains a key component of the local water management infrastructure, emphasizing the importance of sustainable water resource management practices for the future.
