Diversion Dam and Deer Flat Embankments
Diversion Dam and Deer Flat Embankments, Historic dam and embankment system in Ada County and Canyon County, United States.
The Diversion Dam and Deer Flat Embankments consist of three interconnected dams managing water flow across southwestern Idaho's agricultural landscape.
Engineers constructed these water management structures between 1906 and 1912 as part of the U.S. Bureau of Reclamation's Boise Project for regional irrigation.
The National Register of Historic Places listed these dams in 1976, recognizing their role in transforming Idaho's agricultural development and water distribution.
The dam system continues to supply irrigation water to 500,000 acres of farmland throughout the Treasure Valley while generating hydroelectric power.
The three distinct components - Boise River Diversion Dam, Deer Flat Upper Embankment, and Lower Embankment - span 65 acres across two counties.
