The North Platte River runs south to north, its freestone stretches starting in Colorado and crossing the state line just north of Walden, CO. The river passes through Saratoga, WY, pours under I-80 near Sinclair, and bellies into Seminoe Reservoir, which marks the beginning of its famous big-trout tailwater reaches.
Below Seminoe, the riffle, run, picture-perfect Miracle Mile shuffles toward Pathfinder Reservoir. Next up, a steep Fremont Canyon, complete with a sweet switchbacking meadow section ends its journey at Alcova Reservoir. And downstream of that impoundment, Grey Reef Reservoir is the final link in a chain that forms the formidable Grey Reef tailwater fishery—a drift-boat paradise home to myriad float options between our Alcova-based boat ramps and the City of Casper, WY.
This is where you’ll find North Platte Lodge and The Reef Fly Shop. And it’s where extraordinary Wyoming fly fishing begins.
From North Platte Lodge, begin your fishing day on the Grey Reef stretch of the North Platte River, a four-season fishery with healthy populations of wild brown and rainbow trout. The mellow and meandering Reef rolls through wide-open country and averages approximately 3,000 trout per mile: 90 percent rainbow and 10 percent browns and Snake River cutts. Thanks to consistent tailwater flows carrying scuds, leeches, worms, and massive terrestrial and macroinvertebrate life, Grey Reef is a BIG trout powerhouse. Rainbows average 16 to 18 inches long, while trophies span 25 to 30 inches and can weigh 10+ pounds. Our brown trout are equally large, oftentimes more elusive, and are fiendish for big stripped streamers.
The Grey Reef section of the North Platte between Alcova and Casper is almost entirely privately held, which keeps walk-in pressure low. Our miles of private access give you first crack at the Grey Reef’s best runs. The drift-boat fishing we specialize in is primarily a subsurface game with nymphs and streamers. But dry-fly opportunities exist. During seasonal baetis, PMD, Yellow Sally, caddis, trico, midge, and hopper “hatches”, it can be exceptional.
All North Platte Lodge and The Reef Fly Shop guides are CPR/First Aid certified and have their own drift boats. Each boat accommodates two anglers and the guide. Fishing can be done from the comfort of the boat. But, to get the full experience, step out and wade when opportunities arise. We keep all boats and gear clean and orderly for your comfort.
Your typical Wyoming fly fishing day with North Platte Lodge starts with coffee, juices, and a hot (or cold) breakfast in our upstairs dining room. Fly fishing guides (prearranged) will meet guests at the lodge—with lunches, cold beverages, and gear items—and shuttle anglers to the river. Day floats on the Reef range from 4 to 10 miles long. Lunch is served on the water and fishing is concentrated on the stretches that are producing best during your chosen timeframe.
Expect to catch and release a number of spectacular trout. Boating twenty or more fish isn’t uncommon. Many of those fish will push the 18+ inch mark. And keep this in mind:
On the Grey Reef, more 20+ inch trophies are caught daily than most rivers in the country.
If it’s wild, big-shouldered rainbow and brown trout you’re after, North Platte Lodge is your ticket to those once-in-a-lifetime fish.
