Headwaters above Tropic Reservoir
The East Fork begins on the Paunsaugunt Plateau just west of Bryce Canyon National Park and runs about 15 miles of small, high meadow stream above Tropic Reservoir, all of it on Dixie National Forest and reached by gravel forest roads south of Scenic Byway 12 that close in winter. Brook, brown, cutthroat and rainbow trout are all here, with wild browns and cutthroat concentrated toward the headwaters and tributaries such as Crawford Creek and the rainbows spilling out of the stocked reservoir.
Black Canyon and Antimony
Below Tropic Reservoir the river flows north through Johns Valley along State Road 22, past Widtsoe, and into Black Canyon above the town of Antimony. Four public pullouts on SR 22 between Widtsoe and Antimony give access to more than six miles of restored, fenced public water, and it is mostly a brown trout fishery with the odd cutthroat, rainbow or brook trout. From the BLM boundary about four miles south of Antimony upstream to Deer Creek the rule is artificial flies and lures only.
Kingston Canyon
Below Antimony the river feeds Otter Creek Reservoir, and from the dam it runs west through Kingston Canyon along State Road 62 to join the main Sevier near Kingston, where this page's gauge sits. This is an irrigation tailwater with the largest fish in the system, and the DWR secured more than nine miles of public access here in 2004. Private land sits at the head of the canyon and again near Kingston, so watch the signs. Cutthroat, browns and rainbows are all caught here.
Bonneville cutthroat
The Sevier drainage is Bonneville Basin water, so the native trout is the Bonneville cutthroat, and the East Fork's headwater reaches and tributaries count toward the Utah Cutthroat Slam. Circle Valley Anglers in Circleville is the local shop for conditions.
Season and regulations
Utah DWR reports have called 46 cfs at Kingston a perfect level and 175 cfs difficult, and flows in Kingston Canyon are set by Otter Creek releases and irrigation calls rather than snowmelt alone. This page treats 30 to 120 cfs at the Kingston gauge as in range.
The river is open year-round except the feeder canal from the Antimony diversion to Otter Creek Reservoir, which is closed from January 1 until the second Saturday in July. Black Canyon from the BLM boundary up to Deer Creek is artificial flies and lures only; elsewhere Utah's statewide 4-trout limit and general gear rules apply. A Utah license is required.
