Dry Creek Diversion, located in Payette, Idaho, serves as a crucial irrigation structure to manage water resources in the region. Completed in 1976, this earth dam stands at a height of 34.8 feet and has a storage capacity of 77 acre-feet. The dam's primary purpose is irrigation, benefiting from the waters of Dry Creek and Big Willow Creek.

Maintained by a private owner, Dry Creek Diversion is regulated by the Idaho Department of Water Resources, with state permitting, inspection, and enforcement in place. The dam's spillway, with a width of 80 feet, is designed for controlled release of excess water. Despite being classified with a low hazard potential and fair condition assessment, there is a very high risk associated with the structure, highlighting the importance of ongoing risk management measures.

With its strategic location and vital role in water resource management, Dry Creek Diversion stands as a key infrastructure for agricultural activities in the region. Enthusiasts of water resources and climate will find interest in the dam's design, purpose, and the ongoing efforts to ensure its safety and functionality for the surrounding communities.
