Summary

The substantially natural hydrography of the upper Gila River supports one of the highest levels of aquatic and riparian biodiversity in the region, including the largest complement of native fishes and some of the best remaining riparian habitat in the lower Colorado River Basin. Native vegetation dominates the broad and structurally diverse floodplain, creating habitat for hundreds of birds and other wildlife. Two of the Gila’s fish species, spikedace and loach minnow, and a neotropical migratory bird, the southwestern willow flycatcher, are federally listed as endangered. The yellow-billed cuckoo, a candidate species for listing, nests in the Cliff-Gila Valley. Changes to the river’s hydrology, including peak flows, base flows and [...]

Purpose

The goal of this project is to define the ecosystem water needs of the upper Gila River in New Mexico and to assess the probable ecosystem impact of the proposed diversion, considering current and projected future climate. The project identifies potential impacts of change on hydrological processes, riparian vegetation, and aquatic habitat and associated wildlife species. To achieve this goal, synthesis of existing scientific literature specific to the Gila River and southwestern rivers on hydrology; fluvial geomorphology and flood history; stream flow regimes and riparian vegetation ecology; and wildlife and flow relationships is carried out. New analyses of hydrologic, geomorphic, riparian vegetation and fish data are used to evaluate the probable ecosystem impact of diversions under changing climate conditions. Partners develop three flow scenarios: 1) climate change projections for streamflow for the Gila River, including timing and volume of peak flows and base flows; 2) a diversion scenario that compares diversion altered hydro graph (daily flows) to the historical hydrograph to quantify changes in magnitude, frequency, timing, and duration of flows; and 3) the combined effects of climate change and diversion on the flow regime. Upon completion of a background report that incorporates the literature synthesis, data analysis, and modeling, a flow-ecology workshop that gathers additional information about river function to develop flow-ecology response relationships for selected riparian and aquatic species will be conducted. Workshop results will be summarized in a final report.
