Seminoe State Park Fishing Access Site

Nestled up against the base of the Seminoe Mountains at the North end of Seminoe Reservoir lies one of Wyoming’s true treasures, Seminoe State Park. Located 33 miles north from Sinclair, Wyoming on Carbon County road 351, Seminoe State Park is know for its wide open water, local attractions and friendly atmosphere.Close by, on BLM land, are sand dunes that are open to ORV use and within a short drive is the “Miracle Mile”, a fly fishing paradise. For the adventurous, a hike in the near by Seminoe Mountains may bring a chance sighting of a Bighorn Sheep, Elk or one of the many species of wildlife that call the mountains home. Closer to the park, Mule Deer and Pronghorn can be spotted, Coyotes can be heard at night, and many migratory birds can be seen as they stop over in their travels. 

Fed by two rivers, Seminoe Reservoir offers the full range of water-based activities from swimming to boating. The reservoir is known for its solitude, sandy beaches and fishing (trout and walleye). 

Facilities in the park feature potable water, picnic areas, boat ramps, comfort stations, dump station, playgrounds, and improved campsites with gravel pads, tables and fire rings.

Fishing Water Reports
Originating in Jackson County Colorado, The North Platte flows north until it reaches Jasper, Wyoming at which point it turns southeast and eventually empties into the Missouri River. ... moreOver 300 miles of this lengthy river, run within the state’s boundaries, making it Wyoming’s longest tributary of the Missouri. The Upper North Platte is best defined as remote, undeveloped and pristine. For fly fishermen seeking quiet and solitude, this section of the river has much to offer, including 55 miles of heavily forested greenery and Blue Ribbon waters from the Colorado border to a point just shy of Saratoga.

Near the junction of the Encampment, another highly regarded trout stream, the river enters the high plains and runs free until blocked by the Seminoe Dam and reservoir, about 100 miles north of the border. Below Seminole Dam is the smaller Kortes Dam and a short distance downstream from there begins the world famous Miracle Mile. This stretch is not known for dry-fly fishing; for best results, anxious anglers are encouraged to use nymphs, woolly buggers, streamers and glo-bugs that can be fished deep or just under the surface film. Favorite nymphs and emergers, in bedheads and unweighted, include squirrel tails, pheasant tails, hare’s ear and Prince nymphs, flashbacks, caddis larva and caddis pupa. There is full public access along the Mile although accommodations are mainly limited to campsites.

If you are intent on finding the rare and difficult, The Dome Rock Reservoir, located in the North Platte drainage basin, is managed as a finespotted cutthroat fishery although catches are limited and tackle is restricted. Fishing in North Platte reservoirs can also be challenging and rewarding. Seminoe, Pathfinder, and Alcova are excellent sources of both trout and walleye. Another excellent tailwater fishery is located just below the Alcova Reservoir from Grey Reef Dam to Goose Egg, just west of Casper, where you can find cutthroat, rainbows and browns. Since the Miracle Mile tends to be crowded, Grey Reef appears to be taking its place as the fly fishermen’s new “most favored” destination.

Fishing is good along the Miracle Mile, especially in the mid-to-late morning. It has been very windy though. Be prepared for winter conditions on roads. One option for great spring ... morefishing to avoid high winds is the Bighorn river (about 2 hr drive from Casper). We have fished well with a variety of flies. Try red San Juan, orange eggs, and brown and natural leeches.
