The Johnson Valley Reservoir is fed by Sevenmile Creek (from the north) and Lake Creek (from the southwest). The Fremont River passes through Fremont, Loa, Lyman, Bicknell, Teasdale, and Torrey and provides year-round irrigation for the agricultural lands of Rabbit Valley and Caineville. Then it heads through Hanksville and afterward to its mouth.
The Fremont River has a drainage area of 751 square miles (1,950 km2) fed by spring snowmelt off Thousand Lake Mountain, Boulder Mountain, and the northern Henry Mountains. The river is named after John Charles Frémont.[4] It gives its name to the Fremont culture, a Precolumbian archaeological culture.
