Park Reservoir is a reservoir in Sheridan County, Wyoming and covers about 300 acres.
The best plan at Park Reservoir is to choose one arm or shoreline and work it from shallow cover to the first deep break.
What Makes Park Reservoir Different
Park Reservoir in the Bighorn Mountains is a cold mountain water with brook, brown, rainbow, cutthroat, lake trout, splake, and Yellowstone cutthroat.
Cast small spoons or flies near shallow rock for brook and cutthroat trout, use minnow plugs for browns, and jig deeper water for lake trout or splake.
How Park Reservoir Fishes
Several trout and char can look similar here. Correct identification matters, especially when lake trout, splake, brook trout, and more than one cutthroat form share the same water.
Give brook trout, brown trout, cutthroat trout and lake trout separate passes when they use different water at Park Reservoir. Around Park Reservoir, a lure set for one fish should not be dragged through every point, weed edge, and stretch of open water.
For a trip to Park Reservoir, after two bites, note wind, water color, depth, and bottom. At Park Reservoir, repeat that short pattern on the next matching feature instead of starting over across the lake.
Before making a long move, change lure depth or speed once near the best spot at Park Reservoir. When fishing Park Reservoir, that quick test can show whether the fish moved a few feet or the area went quiet.
On Park, let the first two catches set the plan for the next hour. On Park Reservoir, match their depth, nearby cover, lure speed, and the kind of bottom before changing areas, because those clues say more than a single lucky bite.
Fish and Baits
Fish listed for Park include Brook Trout, Brown Trout, Cutthroat Trout, Lake Trout, Rainbow Trout, Splake, and Yellowstone Cutthroat Trout.
For rainbow trout, cast a small spoon, inline spinner, light jig, or fly through cool water at Park.
For brown trout, work a small minnow bait, spoon, or streamer along cool breaks and moving water at Park.
How to Read the Water
At Park, make one shallow pass and one deeper pass on the same shoreline; that shows whether fish are tight to cover or using the first break.
Season by Season
On Park, early in the year, protected water and the first warm afternoon can be the best clues; as the water heats up, check deeper edges without assuming every fish is on the bottom; cooling fall water often makes points and firm banks useful again.
A Simple Tackle Plan
A light spinning rod, thin line, a few small spoons, inline spinners, and jigs cover the listed trout; carry one slightly heavier setup when other fish or windy water call for more control at Park.
At Park, record the wind, water color, depth where fish were holding, and cover after a bite; those four notes are more useful on the next trip than a long list of spots that did not produce.
For a trip to Park, keep the first hour simple: use one moving bait to find active fish, slow down with a jig or natural bait on the best edge, and repeat the same setup when two bites come from matching depth and bottom during that part of the trip.
