Seepage study of the West Side and West canals, Box Elder County, Utah

A study of the gains or losses of the West Side and West Canals from Cutler Reservoir to near Penrose, Box Elder County, Utah, was made to aid in water allocation for the canal system. Four sets of seepage measurements made in 1978 were used in the analysis. Adjustments for fluctuations in flow in the canals were made from information obtained from water-stage recorders operated at selected locations along the canal during the time of each seepage run.

The study showed no detectable gain or loss for the West Side Canal and a net loss of 50 cubic feet per second (1.4 cubic meters per second) for the West Canal. During the seepage runs, an average of 365 cubic feet per second (10.3 cubic meters per second) entered the West Canal; thus, the net loss was 13.7 percent of the available water. About 240 percent of this loss occurred within about 5 percent of the length studied on the West Canal.
