Fishing around Hanna, Wyoming centers almost entirely on still water. The area's lakes and reservoirs sit in high-desert terrain at elevation, which means short summers, cold nights even in July, and fish that tend to run active during the warmer parts of the day rather than at dawn and dusk the way they might in lower country. Hanna Reservoir is the most accessible option right in town, while Shirley Basin Reservoir and Cowden Reservoir require a bit more driving into the basin to the north. Prior Flat Campground adds a camping-and-fishing combo option for anglers who want to stay out overnight. All five listings in this area are lake or reservoir fisheries, so expect still-water techniques to outperform river tactics here. A basic Wyoming fishing license covers most of these waters, but it's worth confirming current regulations with Wyoming Game and Fish before you go, since reservoir access and rules can shift seasonally. This is practical, uncrowded fishing in open country rather than a destination trophy scene, which suits anglers who prefer space over amenities.
Frequently asked questions
What kind of fish can I expect to catch at Hanna Reservoir and the nearby reservoirs?
The listings here are all classified as lake fishing, but the specific stocked or resident species aren't detailed in the available data. Wyoming Game and Fish maintains stocking reports on their website by water body, which is the most reliable way to confirm what's currently in Hanna Reservoir, Shirley Basin Reservoir, or Cowden Reservoir before your trip.
When is the best time of year to fish these waters near Hanna?
The high-desert elevation around Hanna means ice-off typically runs late spring, and productive open-water fishing generally runs from late May through September. Early summer and early fall tend to offer the most consistent action before water temperatures drop sharply. Winter ice fishing is possible on some of these reservoirs, but check current ice conditions and access before heading out.
What time of day fishes best on these reservoirs?
At elevation in Wyoming's open basin country, midday and early afternoon often outperform dawn and dusk, especially in spring and fall when overnight temperatures are cold. In midsummer, early morning and evening can be more productive as daytime heat pushes fish deeper. Wind is a real factor on exposed reservoirs like Shirley Basin, and a light chop often turns fish on.
Can I camp at any of these fishing spots?
Prior Flat Campground is specifically listed as a lake fishing and camping location, making it the clearest option if you want to combine an overnight stay with fishing. For the other reservoirs, dispersed camping may be available on surrounding public land, but confirm access and any fire restrictions with the relevant land management agency before you go.
What gear setup makes sense for reservoir fishing in this area?
A medium spinning or baitcasting outfit in the 6- to 7-foot range handles most still-water situations well. Since all five listings here are lake or reservoir fisheries, bring a mix of jigs, spoons, and bait rigs rather than fly or river gear. Wind on these open-country reservoirs can be significant, so heavier line and weighted presentations help you maintain contact with your lure.
