Smallmouth bass illustration

Smallmouth bass

Best: May-Oct

Current and rock. Finds gravel flats, boulders and drop-offs, and fights far above its weight. Peak season. Tubes, jerkbaits and swimbaits around gravel points, boulders and current seams.

Largemouth bass illustration

Largemouth bass

Best: spring and fall

The headline act on most American reservoirs. Relates to cover: docks, brush, grass edges and points. Prime chasing season. Work moving baits on points and pockets: spinnerbaits, chatterbaits and squarebills, with a stick worm behind for followers.

Northern pike illustration

Northern pike

Best: spring, early winter

The ambush predator of weedbeds and cabbage edges. Aggressive, big and always worth a wire leader. Weedline spinnerbaits, spoons and jerkbaits; bays with fresh green weed hold the active fish.

Rainbow trout illustration

Rainbow trout

Best: Apr-Jun, Sep-Oct

The workhorse of western rivers: riffles, seams and dry-fly eats. Prime dry-fly and hopper season. Match the hatch morning and evening; nymph the seams midday.

About this water

A 22,000-acre Bureau of Reclamation reservoir on the North Platte River, Natrona County, Wyoming, dammed in 1909.

Fishing Pathfinder Reservoir: the full guide

A century-old dam

Pathfinder Reservoir spreads 22,000 acres across the North Platte River canyons southwest of Casper, held by a stone dam completed in 1909. The surrounding country is sage and rock, the water is deep and cold, and the fishery is genuinely mixed: walleye in numbers, rainbow and brown trout, cutthroat, and yellow perch that support both open-water and ice fishing.

Walleye and trout together

Walleye hold the rocky points, shoreline breaks and flats, taking jigs in spring and crawler harnesses trolled through summer. Trout cruise higher in the water column and along the shorelines: trolled spoons and stickbaits produce, especially in spring and fall when fish move shallow. The combination means a day can produce both species on the same structure, unusual and rewarding.

Perch and the wind

Yellow perch school over the flats and provide reliable action for anglers who like fast fishing, and they anchor the winter ice fishery. Wind is the defining condition: this is high Wyoming desert and the reservoir builds serious waves quickly. Mornings are the reliable window, and afternoon plans should include an exit route to a protected shore.

Casper-area logistics

Ramps at Sagebrush, Weiss and the Fremont Canyon area serve the reservoir, with primitive camping around the shoreline. Services are minimal: bring what you need. The Fremont Canyon between Pathfinder and Alcova is spectacular and worth the boat ride. Casper, an hour away, is the nearest full-service town.

Common questions

Walleye and trout in the same lake?

Yes: Pathfinder supports both, often on the same structure, which makes for varied days on the water.

How bad is the wind?

Serious: high desert with no shelter. Fish mornings and always know where your protected water is.

Are there services?

Minimal: primitive camping and boat ramps. Bring fuel, water and supplies from Casper.
