Description - Kortes Reservoir is located in a deep, narrow section of the Black Canyon of the North Platte River, below Seminoe Dam. The Miracle Mile Area extends downstream approximately 5.5 miles from the bottom of Kortes Dam to the boundary of the southern management unit of the Pathfinder National Wildlife Refuge.
- Most of the attractions in the Kortes Reservoir/Miracle Mile area lie along the Miracle Mile. Kortes Reservoir has no boat ramp available due to frequent water surges from Seminoe Dam. There are no campsites immediately adjacent to Kortes Reservoir due to the steepness of the canyon walls. There are no fish stocked in Kortes Reservoir.
There are eleven primitive camping areas in the Miracle Mile. Available fish species include brown trout, cutthroat trout, rainbow trout, and walleye. Rainbow trout are stocked annually in the Miracle Mile. A barrier-free fishing pier and restroom are located at the Miracle Mile. A bill passed by the 90th Congress requires a minimum 500 cfs stream flow downstream from Kortes Dam has helped to maintain a fishery along the Miracle Mile.
Recreation - Recreational benefits at Kortes Reservoir are limited due to its location within a steep and narrow canyon which limits access to the reservoir. Fishing is the primary recreational activity in the area.
