Book excerpt: In semi-arid states such as Wyoming that receive 12 inches or less of rainfall annually, supplemental irrigation water is paramount to maintain productive agricultural systems. Anytime water is stored, transported, or distributed, however, only a fraction makes it to its final destination. Assessment and updating of irrigation system efficiency, and infrastructure, is a recognized need on many western reservations. Irrigation efficiency hasn't been quantified for the Little Wind Unit, the largest irrigation system on the Wind River Indian Reservation (WRIR) in Wyoming, since 1994, when investigators found overall irrigation efficiency to be between 35 and 40%, equating to 4,000 to 8,000 acre-feet of water loss during the irrigation season. In this study, two different methods were used to quantify and locate potential water losses in the Little Wind Unit: the calculation of an agricultural water balance and targeted geophysics techniques. A water balance was developed for May through September from 1990 to 2013 to quantify monthly losses and identify long-term changes in the larger system. In addition, GEM2, an electromagnetic geophysical sensor that measures resistivity with depth, was used to determine seepage loss for the main delivery canal. Synoptic flow measurements were used to assess the effectiveness of the GEM2 in mapping and quantifying seepage losses and to calculate conveyance efficiency. The purpose of the research was to generate site-specific information for the WRIR to assess irrigation system water losses for improved irrigation efficiency for a group of irrigation systems that have historically contributed to unsatisfied water demands among water users. Results of the twenty-four year water balance revealed large errors and data gaps associated with the inflows, outflows, diversions, and precipitation data, which made closing the water balance impossible and identified specific needs for better data. Irrigation efficiencies ranged from 50 to 70% for the LWU, but large variability impacts the understanding of irrigation efficiency. Economic assessment showed that in some years more profits could have been realized with better irrigation efficiencies. Irrigation efficiency decreased linearly with increased diversions for the study period, showing no difference in terms of management (diversions) in wet or dry years. Conveyance efficiencies for reaches measured in the main canal of Ray were greater than 85%. Based on the results, greater temporal and spatial distribution data are needed to fully assess irrigation system performance, in order to make agriculture on the Reservation productive and sustainable.
