The Salt River Project (SRP) supplements the natural flows on the East Verde River with water pumped from Blue Ridge Reservoir on East Clear Creek in Coconino County. The water travels 17 miles (27 km) by pipeline to the East Verde at Washington Park, from whence it flows toward the Verde River and the SRP reservoir behind Horseshoe Dam.[5] A significant fraction of the Blue Ridge water release of 11,000 acre-feet (14,000,000 m3) a year is allocated to communities along or near the East Verde River. The U.S. Congress has set aside 3,000 acre-feet (3,700,000 m3) a year for Payson and 500 acre-feet (620,000 m3) for other northern Gila County communities.[6]
