Fremont Canyon Fly Fishing Guide

Header-Background-Wading-The-North-Platte

The Fremont Canyon and Cardwell stretch of the North Platte River is defined as the section between Pathfinder Reservoir and Alcova Reservoir. In the past 10 years, minimum flows (72cfs), have been established courtesy of the Wyoming Game and Fish Department and Wyoming Fly Casters.

Due to the minimum flows implementation, abundant bug life and intimate nature of this tailwater, it has been increasingly popular with anglers and is truly a world-class fishery. This particular fishery has both rainbow and brown trout with most recent population estimates (2013), courtesy Wyoming Game and Fish, being 248 browns and 947 rainbows per mile, respectively.

Fremont Canyon Fly Fishing: What You Will Catch

There are not as many trout in this section, but plenty for the small size of the stream. Cardwell is a technical place to fish simply because the fish are not easy to catch. However, you can fish this water without getting your feet wet and there are very few obstacles to interfere with casting. Rainbow trout make up a majority of the population for Fremont Canyon fishing, but all species grow to incredible size in the canyon.

Rainbows, Browns, and Cutthroat trout coexist in small numbers in Fremont Canyon. The Wyoming Game and Fish has been attempting to stock this section of the North Platte River for several years but the program has been largely unsuccessful. Their initial study, before the stocking began, found that there were approximately 150 fish per mile, which is still the accepted population of Cardwell. While the stocked fish don’t seem to survive, the wild fish are alive and well, which makes for a more interesting fishery.

The Best Fremont Canyon Fishing Techniques

Midges, baetis, caddis and tricos are the primary hatches at Cardwell and Fremont Canyon. PMDs and sallies also occur here but not with the frequency or size of the other hatches. Aside from these hatches-scuds, leeches, crayfish, annelids and small forage fish round out the diet for Cardwell and Fremont Canyon trout.
As with both the Grey Reef and Miracle Mile sections of the North Platte, Cardwell and Fremont offer fantastic fishing year-round. That being said, nymphing is the most productive technique on a daily basis. While you can nymph all year long, the dry fly fishing and streamer fishing can be some of the best in the whole North Platte system. The dry fly fishing can be consistent when there are baetis, caddis, tricos, and midges present. Concentrate on the flats in the Cardwell section when the fish are looking up. The boulders, deeps pools, and the tailouts hide some aggressive trout waiting to eat your streamer, especially on the cloudy days.

Cardwell Terrain for Fremont Canyon Fishing

As the river leaves Pathfinder Dam it makes its way through a small canyon-before entering what is known as Cardwell. Approximately 1.2 miles in length, this section of the North Platte meanders through the valley floor and would be best characterized as a meadow stream. Pocket water, riffles, seams and small pools make up the Cardwell section of the North Platte. Access is allowed on both sides of the river and it is very wading friendly.

The hike down into the canyon for wade fishing may be difficult; the fishing is well worth it. The Fremont Canyon section of the North Platte is full of boulders, riffles, pools, and large hungry trout! The scenery, with large granite cliffs and abundant wildlife makes this section of the North Platte one that should not be missed. With 1.5-2 miles of fishable water Fremont canyon offers the wading angler an unforgettable experience. That said the wading could be difficult, especially in the winter when there is ice present on already slippery boulders.
