Pathfinder Reservoir is a reservoir in Carbon County, Wyoming and covers about 22,012 acres.
Pathfinder Reservoir is big water, and a useful pattern in one arm may not carry to the far end of the lake.
What Makes Pathfinder Reservoir Different
Pathfinder Reservoir receives both the North Platte and Sweetwater rivers. Long arms and changing irrigation storage make present channel edges more useful than an old full-pool shoreline.
Jig or use a bottom bouncer for walleye, troll small lures for kokanee, and cast spoons or minnow plugs for rainbow and brown trout.
How Pathfinder Reservoir Fishes
Pathfinder Dam is built from granite quarried nearby, and the reservoir stores much of the North Platte Project's water. Large seasonal changes can expose old points and move fish toward the original river path.
Give walleye, rainbow trout, brown trout and kokanee salmon separate passes when they use different water. Around Pathfinder 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 Pathfinder Reservoir, after two bites, note wind, water color, depth, and bottom. At Pathfinder 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 Pathfinder Reservoir. When fishing Pathfinder Reservoir, that quick test can show whether the fish moved a few feet or the area went quiet.
On Pathfinder Reservoir, let the first two catches set the plan for the next hour. On Pathfinder 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 Pathfinder include Walleye, Rainbow Trout, Brown Trout, Kokanee Salmon, and Snake River Cutthroat Trout.
For walleye, work a jig, minnow rig, or small crankbait along points and the old channel edge at Pathfinder.
For rainbow trout, cast a small spoon, inline spinner, light jig, or fly through cool water at Pathfinder.
For brown trout, work a small minnow bait, spoon, or streamer along cool breaks and moving water at Pathfinder.
How to Read the Water
At Pathfinder, 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
In spring, start with warming banks, creek mouths, and shallow cover; summer usually pushes the better bite toward the outside weed edge or a nearby drop; fall can bring bait back to windblown points, while winter calls for smaller moves and a slower pace at Pathfinder.
A Simple Tackle Plan
When fishing Pathfinder, 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.
Record the wind, water color, water depth at the strike, 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 at Pathfinder.
At Pathfinder, 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.
