The purpose of the CCRN is to implement a regional network of water-management projects that meet the long-term needs of the Sierra Vista Subwatershed, and the vision is a flowing San Pedro River, the conservation of water resources, and a vibrant local economy. CCRN was formed 2015 by the City of Sierra Vista, Cochise County, Hereford Natural Resource Conservation District, and The Nature Conservancy. The City of Bisbee joined in 2016.
The CCRN Roadmap is the plan for implementing the CCRN purpose and vision, and establishes goals in the areas of recharge, conservation, and funding. The CCRN developed specific objectives and strategies for each of these goals that are to be implemented over a five-year time span, and which are periodically reviewed and updated as necessary to meet the goals.
As of 2018, the Cochise Conservation and Recharge Network consists of six sites, totaling 6,344 acres along the Upper San Pedro River, as shown on the Site Location Map. Each site has been selected for its potential to recharge and/or conserve water to benefit the river. The sites offer diverse but complementary hydrologic functions at a regional scale. These functions include the ability to retire historic high-volume pumping, and/or to preclude high-volume future pumping near the alluvial aquifer, and to recharge effluent, urban enhanced runoff (UER) and/or diffuse stormwater in key locations. Additional sites that are capable of enhancing the vision of the CCRN may also complement this network and be promoted by the CCRN in the future.
The CCRN hydrologic monitoring program also measures and tracks data on groundwater level changes and water flowing to the sites, both at future project sites and at operational project sites. The table below shows how much water has been recharged and/or conserved since the CCRN formed in 2015. However, it’s important to note that the Sierra Vista Environmental Operations Park has been operating since 2002 and has now recharged over 10 billion gallons*!
*For reference, 10 billion gallons equals about 30,000 acre-feet. Since 1 acre-foot would cover about the area of a football field 1-foot deep, the EOP has recharged the equivalent of a football field covered by 30,000 feet of water, which would reach a height just shy of an airplane’s cruising altitude.
