Weekly Report

Report DateOct. 14, 2021

Since the end of last week, flows on the Poudre have risen steadily. As a result, productivity has improved. While air temps are dropping fast and overnight lows are consistently nearing freezing, the hopper dropper or dry dropper continues to produce the best results. That said, with higher flows the nymph rig has become increasingly effective as there is more deep and slow water to be targeted. While trout here are not terribly selective when it comes to your flies, they will feed more heavily in the riffles and runs where they have less time to analyze the offering. When fishing a dry dropper, we like to lead with an Amy’s Ant or Elk Hair Caddis followed by one or more smaller searchers/attractors like a Flashback PT, Guide’s Choice Hare’s Ear, Perdigon, Rainbow Warrior, red/green Copper John or Frenchie to start. Otherwise, we’ll fish smaller imitations in the midge and baetis variety to really hone it in. Keep it simple when it comes to your imitations. Black or purple Zebra Midges, Black Beauties, Mercury Midges, RS2s, Darth Baetis and Juju Baetis are a few of our go-to patterns right now. If you find some deep and slower water, don’t hesitate to rig up a nymph rig. Lead with bigger flies followed by smaller imitations if you go this route. While hatch activity has been fairly consistent with midge and BWOs making regular appearances, surface action has been hit or miss. Regardless, if you see trout actively rising, don’t hesitate to rig up a single, double or dry to an emerger rig. Lastly, smaller streamers are becoming increasingly effective as territorial browns gear up to spawn.

Detailed River Info

Background

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. 

Angling

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
