Red Creek, flowing through Daggett County, Utah and Sweetwater County, Wyoming before joining the Green River, presents a unique fishing opportunity characterized by its variable conditions. This tributary drains a large high desert area and creates the Green River's largest rapid at its confluence. The creek carries distinctive red clay-stained water during rainy periods and spring runoff, which significantly impacts fishing conditions both in the creek itself and downstream in the Green River. Red Creek contains rainbow and brown trout, though fishing can be challenging due to its tendency to run muddy for much of spring and early summer.
