a good place for trout fishing

Casper - If beautiful scenery, few crowds, and excellent trout fishing are your thing, then this would be a good year to head to Seminoe Reservoir. With excellent survival of the nearly 100,000 rainbow trout stocked annually out of the Dan Speas Fish Hatchery, the trout population has continued to improve. Sampling last spring showed mostly two and three-year-old rainbow trout that averaged over 14.3 inches and 1.3 pounds, with a few fish upwards of 20 inches. Anglers venturing to the southernmost reservoir on the North Platte could also potentially hook into a very nice wild brown trout, particularly if they focus their efforts in the Platte Arm. While far fewer browns were captured during our trout netting, the biggest measured in at 26.6 inches and 10.8 pounds!
 
In addition to its booming trout population, Seminoe Reservoir is also well-known for supporting a healthy walleye fishery. After rising steadily from 2011 to 2015, the walleye population has remained fairly consistent over the past four years. Fall sampling showed that this leveling-off of the population is being driven by good recruitment in 2015 and 2016 and a nearly equal reduction in the number of fish over 15 inches. This reduction of older fish is most likely a combination of poor recruitment from a number of years ago that resulted in weak year-classes and considerable harvest of walleye once they reach 14 to 16 inches in length. However, many fish do manage to survive this bottleneck, and there are large fish prowling the lake, the largest in our sample was 31.0 inches and 8.7 pounds. That said, walleye in Seminoe grow very slowly, and it could be a few years before the current average length of 14.6 inches sees much of an increase.
