Seminoe Reservoir is the uppermost reservoir on the North Platte River and is primarily known for its excellent rainbow trout fishery and for occasionally producing a 10+ pound walleye. Cutthroat trout, brown trout, and lake trout are also present in much lower numbers.
In GF netting surveys, the rainbow trout averaged 14.2 inches and 1.1 pounds and the walleye averaged 14.6 inches and 1.4 pounds. The largest walleye we captured in our 2003 fall netting survey was 31.8 inches and 11.8 pounds.
The rainbow trout fishery is maintained almost entirely through the annual stocking of 125,000 eight inch trout. The walleye fishery is maintained entirely through natural reproduction.
The drought has had moderate impacts on this fishery. Both rainbow trout and walleye are slightly skinnier now than they were just a few years ago. Impacts to reservoir access have been more severe. In April of 2003, there were no usable boat ramps on Seminoe Reservoir. The GF worked cooperatively with Seminoe State Park to temporarily extend the low water ramp at North Red Hills to regain boating access. The privately owned ramp at the Seminoe Boat Club was also usable for most of the summer months.
The fishing at Seminoe remained excellent despite the drought. Many of you were likely interviewed by one of our creel clerks. Anglers targeting trout had an average catch rate of 0.65 rainbow trout per hour and the average length of harvested rainbow trout was 15.7 inches. Anglers targeting walleye had an average catch rate of 0.42 walleye per hour and the average length of harvested walleye was 13.8 inches.
Nearly 70% of the anglers we interviewed said they were satisfied with the Seminoe Reservoir fishery.
