Weekly Report

Report DateSept. 16, 2021

The Poudre River continues to improve following the mudslides back in July and water clarity is starting to get back to normal on the lower stretches. That said, it is still off-colored and the fishing has been a challenge here. The further up the canyon you go, the better conditions will be. Comparatively warm overnight temps have kept the water on the lower stretches from cooling down so keep this in mind as well. Again, the upper stretches will be more favorable from this perspective as well with cooler water temps. At this point, the hopper dropper, dry dropper or nymph rig has proven the most effective. If you are fishing a skinny section, keep it light and go with a dry dropper. Otherwise, if you find a deep run or pool, don’t hesitate to thoroughly nymph it. As far as dry droppers go, an Elk Hair caddis has been our go-to lead fly, while Amy's Ants, Micro Chubbys and Hippie Stompers are a close second, third and fourth. Trail with one or more smaller searchers/attractors like a red Copper Johns, Flashback PTs, Guide’s Choice Hare’s Ears, Perdigon or Rainbow Warriors, but don’t discount the smaller midge, baetis and caddis imitations. As for nymphing, air pressure will be on the lower end for the majority of the next seven days, with the exception of Friday (9/17) and Saturday (9/18). As such, bigger attractors/searchers at the lead will be the most effective. Stoneflies, like a Pat’s (brown/tan), Golden Stone or Guide’s Choice Hare’s Ear have been top producers. Otherwise, a smaller leech or worm should do the trick as well. Trail any of the aforementioned lead flies with one or more of the aforementioned smaller imitations or searchers/attractors.

Detailed River Info


The Poudre River, or Cache La Poudre, gets its name from the local legend dating back to the 1830’s when a crew of French explorers made their way along the river and found themselves in a blinding snowstorm. In order to cross the river and make their way to safety, they were forced to “cache la poudre”, French for stash the powder, leaving behind their heavy gunpowder kegs. The story goes that the explorers returned the following spring to find the gunpowder undisturbed. Subsequent travelers heard the story and the name stuck.

The Poudre is a freestone river that originates in Rocky Mountain National Park. From the headwaters, the river travels North until it reaches the small unincorporated town of Kinikinik, in western Larimer County, before turning east making its way  through the Poudre Canyon toward Fort Collins. Here you’ll find a combination of fast runs and riffles as well as some wide and comparatively slow water. While the fishing is great near the park, for the sake of this report, we’ll be referencing the stretch through the Poudre Canyon. In general, you should manage to find some solitude most of the year. However, the summers are particularly busy and you’ll find yourself sharing the water with other outdoor recreationalist via raft, kayak and tubes. 


The Poudre is relatively forgiving and beginner friendly. While a number of sections come with heavy brush, it isn’t hard to find open water and is easily accessible from the banks. It is home to a strong population of brown and rainbow trout, but has been known to hold a few cutbows and greenback cutthroats the closer you get to the park. While you can fish the Poudre most of the year, the late spring, early summer and fall present the best conditions. In the winter months, barring extreme cold, you can fish the lower canyon as the water is deeper and less prone to freezing. The Poudre experiences the standard Colorado hatches with midges hatching throughout the year, mayflies in the late spring through fall, and caddis and stoneflies in the summer. While you can’t go wrong with a standard double or triple nymph rig, the late summer and early fall present some great hopper dropper opportunities. Additionally, streamers are particularly effective in the spring and fall. 

River Access

While the lower and upper canyon present slightly different terrain, the Poudre is one of those rivers where you really can’t go wrong in terms of access points. There are a number of great public access points off of Highway 14 and we strongly encourage you to start exploring. If you are coming from Fort Collins, head north toward Laporte on Hwy 287 until you reach Hwy 14. From there, drive up the canyon until you find a suitable pull off. In general, the further you’re willing the drive, the fewer crowds you will see and the less pressured the trout will be
