Flaming Gorge Reservoir
To fish across state lines at Flaming Gorge, you must have a valid fishing license from one state and a reciprocal fishing permit from the other state. For example, if you buy a Utah resident or nonresident fishing license, you can fish the Utah portion of Flaming Gorge. After buying your Utah license, if you decide you also want to fish the Wyoming portion of the reservoir, you must buy a Wyoming reciprocal fishing permit.
For more information on obtaining a Wyoming
reciprocal fishing permit, call the Wyoming Game and Fish Department at (307) 777-4600.
Utah reciprocal fishing permits are available at wildlife.utah.gov and from Utah Division of Wildlife Resources offices and license agents that sell Utah fishing licenses.
A Wyoming second-pole permit is not valid in Utah, even with a reciprocal fishing permit. A Utah second-pole permit must be purchased if you’d like to fish in Utah with two poles at the same time. Hope this explains it. This is taken from the Utah Fishing Guidebook.
