The Watershed Planning in the Upper Gila Watershed project is a partnership between the WRRC, the Gila Watershed Partnership (GWP) and Arizona Cooperative Extension. In 2012-2014, our work in the watershed was funded by a grant from the Bureau of Reclamation WaterSMART program to complete an evaluation of current watershed conditions and develop future scenarios based on stakeholder input. The first grant through WaterSMART ended on September 1, 2014. An additional two years of funding for water planning in the watershed was secured from the Bureau of Reclamation through a Desert Ecosystem Cooperative Studies Unit agreement. This grant began on October 1, 2014 and will be used by the WRRC and our partners to: build upon the previously developed scenarios, help residents in the watershed better understand their water resources, and develop a decision support system for watershed management.
This project will develop effective decision making tools for watershed planning on Arizona reaches of the Upper Gila River. The project has four phases, including: 1) Determination of water management needs and objectives, 2) Estimation of water supply and demand and creation of water supply and management strategies and alternatives, 3) Development of metrics, and 4) Creation of a water resources plan.
The Gila River originates in the Mongollon Mountains of New Mexico and flows West across Arizona to join the Colorado River at the California border near Yuma. Graham and Greenlee Counties, in the heart of the Upper Gila Watershed, depend on water supplies from the river to support their municipal, agricultural and recreational activities. In this arid climate, water planning is essential to ensure the lifestyle enjoyed by local residents.
According to the Arizona Water Resources Development Commission (WRDC), the Upper Gila Watershed will have unmet water demands by 2035. Over the past two decades, municipal water demand in the watershed has increased by 34 percent, while agricultural demand has decreased by only 5 percent. As water users and other watershed stakeholders look ahead to an uncertain future, water management challenges raise several important questions. How are we currently using our water? What trends in water use and water availability can be identified today? How will changes in future water availability as a result of drought, fire and other impacts affect the watershed and its natural resources?

This project directly benefits water management in the Upper Gila Watershed by providing new resources to aid the community as it plans for the future. The key to this effort is integrating local stakeholder concerns into the project, instead of generating yet another study. The Assessment will enable water managers and other stakeholders to evaluate the current conditions of the watershed, the potential impacts of climate change on water resources and the environment, and the impacts of management actions within this context. Information and resources generated as part of the Assessment will allow the GWP and other community stakeholders to develop a long-term, comprehensive watershed management plan.
Atlas of the Upper Gila River Watershed
The Participatory Watershed Assessment for the Upper Gila River project has completed our Atlas of the Upper Gila River Watershed and presented it to the Gila Watershed Partnership and our steering committee on January 8th, 2014. The Atlas is a compilation of the natural, water and cultural resources of the Upper Gila River Watershed and is designed to be the starting point for future watershed planning. In 2014 the WRRC, Arizona Cooperative Extension and the Gila Watershed Partnership will use the discussion of the current conditions described in the Atlas and the challenges associated with those conditions, to develop a set of scenarios decreeing the potential future condition of the watershed. Because it contains many maps and graphics, the entire Atlas can only be downloaded at a lower image quality.
