CCRN projects provided more than 6,000 acre-feet (AF) of water benefits in 2021 and a total of more than 41,000 AF since 2015. CCRN tracks the cumulative water benefits as recharge, retired historical pumping, and precluded future pumping. Other projects being pursued by individual members are not reflected on the list tracked by CCRN.
Among the 8 sites, the Sierra Vista Environmental Operations Park (EOP) Effluent Recharge project and Three Canyons Conservation Site are responsible for nearly 80% of the calculated water benefits accrued by the network through recharge and retired pumping, respectively.
The CCRN methodology for calculating the water benefits is generally consistent with the 2014 Biological Opinion for Fort Huachuca. Precluded pumping is calculated from the zoning density of the parcel with an average of 2.5 people per household, at a per capita usage of 118 gallons. Retired pumping is based on acres retired with a water duty of 3.4 AF/acre. (Note this number was revised retroactively in 2021.)
