Fort Huachuca and the San Pedro River: Improving Water Deficit Liability Calculations Through Economic Modeling.

Arizona’s San Pedro River is one of the nation’s hotspots of biological diversity, providing critical habitat for over 350 species of birds, 80 mammals, two native and several introduced species of fish, and more than 40 species of amphibians and reptiles Groundwater pumping jeopardizes the health of the river, and Ft. Huachuca is by far the biggest culprit. CSE completed a study for the Center for Biologcial Diversity that points out serious shortcomings of Ft. Huachuca’s population-based method for establishing its groundwater deficit liability and responsibility for mitigation. While Ft. Huachuca claims its liability may be as low as 35%, economic modeling suggests its liability is more likely to be in the range of 80%. Read:
