Case Study: Saving the San Pedro River
Adam Czekanski17 November 2005
Agenda
• Geographic Setting
• The Water Deficit
• Saving the San Pedro
• The Upper San Pedro Partnership
• Questions
Geographic Setting
• Flows north from the mountains of Sonora, Mexico
• Perennial flow from Hereford to Fairbank, AZ (~ 20 miles) due to groundwater forced to the surface by bedrock
• Remainder of river is primarily ephemeral

The Water Deficit
• Groundwater that sustains the San Pedro is required by two primary groups:
– The local community– The ecosystem of the San Pedro River
• Recharge of groundwater occurs through:
– Mountain front recharge– Streambed infiltration– Groundwater underflow from Mexico
Local Community
• Greater Fort Huachuca / Sierra Vista community
• Farmers
• Ranchers
• Mining / Industry
San Pedro Ecosystem
• Over four million birds use the San Pedro basin during yearly migration
• Supports 80 species of mammals (2nd most in the world)
• Home to more than 40 species of reptiles and amphibians

Saving the San Pedro
• 1988 – Congress designates 69 km stretch of San Pedro as San Pedro Riparian National Conservation Area (SPRNCA)
• Livestock grazing, water diversions, and mining prohibited

Upper San Pedro Partnership
• The Upper San Pedro Partnership (USPP) is a consortium of 21 agencies and organizations
• All agencies and organizations own or control land and/or water use, and have the ability and authority to identify and implement policies and projects
Upper San Pedro Partnership(Land Owners and/or Land or Water Use Controllers)
• Local Agencies – Cochise County– Sierra Vista– Huachuca City– Bisbee– Tombstone
• State Agencies – State Land Department, – Dept. of Water Resources
• Federal Agencies – Fort Huachuca – Bureau of Land
Management – U.S. Forest Service – National Park Service – Bureau of Reclamation
• Other Organizations – The Nature Conservancy – Audubon Arizona – Bella Vista Ranches
Upper San Pedro Partnership(Resource Agencies)
• State Agencies – Department of
Environmental Quality– Arizona Association of
Conservation Districts
• Other Agencies – Hereford NRCD
(Natural Resource Conservation District)
• Federal Agencies – U.S. Geological
Survey– USDA Agricultural
Research Service– Fish and Wildlife
Service
Upper San Pedro Partnership
• The overall goal of the USPP is to:
Ensure an adequate long-term groundwater supply is available to meet the reasonable needs of both the area's residents and
property owners (current & future) and the San Pedro Riparian NCA. (USPP Organizational Documents)
• USPP does NOT make policy decisions, but provides the framework to research, plan, fund, and implement projects and policies through member agencies
• Publishes annual Water Management and Conservation Plan as a working document to outline planning, research, and progress
• Seeks to eliminate deficit groundwater pumping by 2011
Upper San Pedro Partnership
• Planning
– Reduce current water use (efficient fixtures, better water practices by the public)
– Avoidance of future water use (legislation, ordinances)
– Methods to recharge the aquifer

Upper San Pedro Partnership
• Research
– Groundwater modeling
– Water augmentation studies
– San Pedro Riparian NCA studies

Upper San Pedro Partnership
• Implementation of Measures– Recharging of aquifer with
treated effluent by Sierra Vista and Fort Huachuca
– Purchase and retirement of irrigated and grazing lands
– Large scale installation of water efficient fixtures
– Local laws governing turf use and care
– Coordination with Mexican government for conservation projects in headwater region
• Net groundwater demand has been cut nearly in half since late 2002

Questions
• What is the most critical feature of the Upper San Pedro Partnership that has enabled it to be so successful in such a short period of time?
• Will there come a point when the requirements for economic growth and prosperity in the Sierra Vista / Fort Huachuca area will outweigh the need to stringently protect the river and its ecosystem?
