PROGRAM DESCRIPTION Introduction The Utah-Colorado White River Simulation program is an expansion of the I White River Reservoir Simulation Program developed by the Utah Division of Water Resources. The original program simulated 1 reservoir and 1 land use area in Colorado and 1 reservoir and 3 land use areas in Utah. The expanded program simulates 2 reservoirs and 3 land use areas in Colorado. The Utah portion of the program was unchanged. The water supply for the original program was based on the White River at Watson streamgaging station and assumed a fixed percentage of the supply was available for use in Colorado and the remaining water was made available at the Utah reservoir. The expanded simulation uses 5 streamgaging stations. These stations include: (1) North Fork of White River at Buford, (2) South Fork of White River at Buford, (3) White River below Meeker, (4) White River at Watson, and (5) The White River at Ouray. The program adds the flows of the North and South Forks to obtain the flow at Buford. The program computes reach gains between Buford and Meeker, Meeker and Watson, and Watson and Ouray, which are added to the River flow as the simulation proceeds downstream. The White River Reservoir simulation program is written in Fortran computer language. The program computations are based on mean monthly values. A schematic diagram of the basic elements of the program is shown on Figure 1. Table 1 defines the variables shown on Figure 1. The program regulates the streamflow into the reservoirs; computes evaporation and minimum flows; releases water upon demand to the service areas; computes return flows; and computes hydropower production at the Utah White River Dam if a hydro plant is specified. All streamflows, demands, evaporation and reservoir storage are compute( in acre-feet. A reservoir can be eliminated from the simulation by settirg the maximum and minimum storage values to zero. 0338
