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 20,000-acre reservoir on the North Platte River, Carbon County, Wyoming, between the Seminoe Mountains and sand dunes.

Fishing Seminoe Reservoir: the full guide

Sand dunes and cold water

Seminoe Reservoir floods 20,000 acres of the North Platte River valley in central Wyoming, ringed by sagebrush and the Seminoe sand dunes. Despite the desert setting, the water is cold and deep enough to grow trophy trout: rainbows and browns that reach several pounds on abundant forage. Walleye have established themselves in recent decades, adding a second fishery that continues to grow.

Trout tactics

Trolling is the standard method: spoons, crankbaits and worm harnesses pulled along the shoreline drop-offs and points, shallow in spring and fall, deeper through summer. Big browns hunt the rocky shorelines in low light, and casting jerkbaits at dawn produces the season’s better fish. Shore anglers do well from the rocky points and near the inflow when fish push shallow.

Walleye and the North Platte

Walleye have grown in numbers and now support a legitimate fishery on the flats and points: jigs and crawler harnesses in the classic depths. Below the dam, the North Platte River runs through the Miracle Mile: a famous stretch of trophy trout water between Seminoe and Pathfinder reservoirs, drawing fly anglers from across the region. Fishing both in one trip is the standard plan.

Remote logistics

Seminoe State Park provides ramps and campgrounds, reached by a long gravel road from Sinclair. Services are minimal: bring fuel, water and supplies. Wind sweeps the reservoir relentlessly, and weather changes fast at this elevation. The isolation is the appeal: on weekdays you may see nobody, in one of the more striking landscapes in Wyoming fishing.

Common questions

How big do the trout get?

Rainbows and browns of several pounds are realistic, with the forage-rich water producing genuine trophies most seasons.

What is the Miracle Mile?

The famous stretch of North Platte between Seminoe and Pathfinder reservoirs: trophy trout water and a destination in its own right.

How remote is it?

Genuinely: a long gravel road, minimal services and no cell coverage. Bring everything you need.
