Riverstone Site

The Riverstone Site is located on the west side of the San Pedro River and is managed by Cochise County. A conservation easement on the 1811-acre parcel is held by The Nature Conservancy and conserves an estimated 149-acre-feet/year of groundwater that will not be pumped due to precluded development. The goal of a future recharge project at the Riverstone Site is to raise groundwater levels under the project, increase downstream base flow in about 15-miles of the San Pedro River, and connect sections of the river that do not flow year-round. Initial project studies were conducted in 2015. Groundwater and surface water monitoring began in 2016 and is ongoing.

Mission

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.
