Below you will find all major points of the Poudre River. Message us if you want more added! This doesn’t have the best fishing holes in it, just general points and public access. Fortunately, with this river anglers have access good public fishing spots almost everywhere. Especially from Fort Collins all the way to Poudre Lake with various parking spots, public spaces, and road pull-offs.

The River System

The Cache La Poudre River is an awesome river system that flows from Rocky Mountain National Park’s Poudre Lake, flows through Poudre Canyon into Fort Collins, continues eastward towards Greeley, and eventually empties into the South Platte River.

This is an extremely popular river system. Rafting is common in Poudre Canyon, and tubers, and swimmers are common from Poudre Canyon all the way through Fort Collins.

30 Miles of this river are classified as Wild and Scenic by the National Parks Service. It also contains two sections considered Wild Trout Waters by the Colorado Division of Wildlife.

The average flow of this river is 162 cu ft/s (4.6 m3/s). During snowmelt in spring, the river substantially increases above this, and during low water times can often appear to be barely flowing. Aside from complete washout conditions, there are fishable sections all over this river at nearly every flow level.

What Fish Are In The Poudre?

The Poudre is most well known for the abundant trout population. The river system contains rainbow trout, cutthroat trout, cut-bow trout, arctic grayling, and brown trout.

If you are in search of cutthroat, you should fish closer to Rocky Mountain National Park near the headwaters. This river on average has mostly smaller fish in the 12 inch range, but there are some pretty big fish in here, and 20 inches plus is not that uncommon.

Best Places to Fish the Cache La Poudre

Nearly every section of this river holds a ton of fish, and has great fishing conditions. Whether you want to stay in Fort Collins, or drive up Highway 14 into Poudre Canyon, you’ll be able to find fish.

This river has ample wading opportunities, but you can actually fish almost all of this river from the shoreline if you wanted to.

Poudre Canyon

Poudre Canyon is stunningly beautiful. You’ll find yourself surrounded by cliffs, mountains, elk, bighorn sheep, and just all around gorgeous scenery. If you have the time, be sure to head up into the canyon. Be aware that you will have no cell service at all within the canyon.

You’ll find endless water of all types in the canyon, and fish can be caught by any fly fishing method. Many will say that the fishing simply continues to just get better as you head closer to the headwaters of Poudre Lake.

As far as river access, your options are endless. Highway 14 stays along the river just about the whole time, and there are endless campgrounds, pull-offs, and hiking trails that allow you to fish easily just about every inch of water that is on public land.

Our best advice is to simply drive along, looking at the river, and pulling over wherever you feel like it. There are no bad spots to stop, other than the ones filled with other anglers and tubers. Find some water to yourself and get after it.

If you love camping, there are tons of campgrounds in Poudre Canyon. Take advantage. Here is a resource for you on camping in Poudre Canyon (scroll to the camping section, and expand the link for all of the campgrounds): https://www.fs.usda.gov/recarea/arp/recarea/?recid=81605

Fort Collins

As the river leaves the canyon and flows towards Fort Collins, you’ll be driving by a lot of private land and farm. Eventually the river flows to the town of Fort Collins where the river access is yet again incredible. The Poudre Trail is a paved bike and walking path that allows anglers, bikers, runners, walkers, and everyone else to easily walk right next to the river all the way through town and back out of town.

You’ll find a lot of people here year round, but the fishing is still stellar at all times. You can either walk on this path, bike on it, or drive to different parking lots scattered along the Poudre Trail. Again, it is impossible to single out any locations, because there are so many productive sections, and public access options.

We highly recommend parking your car at a park, and walking the Poudre Trail to different fishing holes. Then, hopping back in the car, and continuing on to the next park. This is a great way to get a lot of river covered if you are looking to discover a few of your favorite spots in town.

Seasons

The Cache La Poudre River is open and fishable year round. Crowds subside in winter, but you will still see anglers in the canyon area, and plenty of runners and bikers along the Poudre Trail. Some areas during winter get ice covered making fishing difficult or impossible, but generally there is always water to fish.

This river fishes great year round. The fishing in the Fort Collins area gets a lot tougher when water levels are low, but you can still always find fish.

Summer brings great dry fly and terrestrial fishing, while winter means a lot more success with small nymphs.

Best Flies for The Poudre

Dry fly dropper setups work very well. During summer months, hopper patterns work great.

Streamers are always a great backup plan, and nymphs work year round. Terrestrials and beetles do well for dry flies in summer months. Size 16-20 tends to be best for wet flies.

When the water is slow and clear, you are going to want to fish small. Size 20 midges are effective. The RS2 is a great fly for this river as well.

Much of this river is heavily fished, and very clear and slow, making these fish particularly hard to fool in certain conditions. 6x or smaller tippet and tiny flies are often needed when the water is low.
