Horseshoe Draw Sediment Control and Stormwater Recharge Project

The Horseshoe Draw Sediment Control and Stormwater Recharge Project is located on the San Jose Ranch, on the east side of the San Pedro River, and is managed by Cochise County. The goal of the project is to prevent further erosion of a healthy sacaton grassland and control excessive sediment and e coli from being flushed into the San Pedro River. It is estimated that the large detention basin will also recharge some water to the aquifer. Project studies and planning were conducted in 2015-2016, with design and construction completed in 2017. Project operation also began in 2017. Surface water monitoring began in 2016, one year before project construction, and is ongoing.

Before the project was constructed, a large head-cut had been steadily eroding Horseshoe Draw upstream of its confluence with the San Pedro River. This video was capture with drone survey technology that allows us to compare changes in geomorphology, or the shape of the draw, before and after construction:  

A large detention basin was constructed on Horseshoe Draw, upstream of the area where excessive amounts of sediment were eroding down the draw, causing problems for downstream roads and the San Pedro River. (photo credit Pat Call)


The mission of the Cochise Conservation & Recharge Network (CCRN) is to implement a regional network of land and water management projects that result in a healthy watershed, flowing San Pedro River, conservation of water resources, and a vibrant local economy.
