Notes from the landowner

Nestled just 35 minutes from Silverthorne, CO, the 1.4 miles of the Upper Williams Fork River offers a welcoming escape for anglers seeking a challenge in a serene environment. The property boasts diverse terrain, presenting anglers with a variety of angling opportunities, including shallow and deep runs, as well as pools. The river gracefully meanders through a partially open canyon on the upper and middle sections, while downstream transforms into a canyon accessible to nimble anglers. Stretching over 45 miles, this portion of the river above Williams Fork Reservoir is not only a freestone river, but a haven for fly fishermen in search of a quiet stream amidst rolling hills, far from highways and foot traffic. The bank can be very inaccessible in high water, you will want to wait for the water to get below the high water mark so there is room for you to scramble down to the river. Rocks are very slippery.

This property is a beautiful but technical property, both when navigating the grounds and when it comes to fishing. You need to be in shape and prepared to fish this property, but the challenge can be worth it if you are up for the adventure. July, August, and September will most likely be the best months to fish this property as the water will have receded enough for you to down to the river.

Anglers can expect the easiest access near the parking area. The banks are gradual in this area. Downstream has steeper access but may be very rewarding and feels very remote. Large pools and great runs. Upstream access has gradual and steeper access throughout.

Game and habitat information

The river’s size is ideal for rainbows, browns, and the occasional cutthroat trout. Fish in the river range from 4 to 18 inches, offering a satisfying angling experience. For equipment, anglers are recommended to use 8’6″ 4wt and 9′ 5wt rods. A small pond on the property adds to the allure, potentially housing fish depending on the time of year. It serves as an excellent spot for kids to practice casting. Fly recommendations include midges, BWOs (Blue Winged Olives), caddis, stoneflies, and hoppers, ensuring a well-prepared and rewarding fishing experience in this picturesque corner of nature.

Fishing was good despite low water (+/- 10cfs). Walked downstream and fished up using a small chubby hitting poacket water. The gate was a little tough. There's a padlock and an electric gate so make sure you understand this when yuou go.

44 cfs at leal was a little low for the river. The day was amazing and I hiked the entire property checking for holes and runs that would be better when flow increases to around 60-80 cfs. Staying on the left side of the river is requires wading in the river but doable and there are some amazingly fishy spots above where the property line requires IO members to stay on the left.

Nice property…although water level was low (~30cfs), the bottom third and top third access was challenging. I focused my efforts on the middle third, both above and below the bridge (which is roughly in the middle of the property). I can see why some members found it hard to fish during high water level months…most of the property is essentially inaccessible. I did manage to catch a handful of trout, including 2 decent size browns and one fat brookie. I tried dries for a while but surprisingly there was little interest. I caught most fish on a small streamer. When fish were present, the takes were aggressive. Word of caution: in addition to challenging river access, the river bottom is also very slippery. Contrary to what is indicated, there is no cell coverage if you are with Verizon. Also, there does not appear to be any fish in the ponds. Bottom line: if you like to bushwack and are looking for a good workout, this is the place for you. I suspect the bottom third and top third could be rewarding for the angler willing to put in the sweat equity required to access these parts.

For properties listed as "Community Adventures" there is the possibility that a limited number of other anglers can be on the property at the same time. Just a heads up, some of our spots have other leases that might have anglers casting their lines too. So, hit 'request to book' and we'll make sure to confirm the availability before you pack your gear!

We think it's important to mentor the next generation of anglers. Youth between the ages of 13 and 17 are 50% off for all fishing and small game when you reserve on the Infinite Outdoors app. However, kids 13-17 will need to have an Infinite Outdoors Membership. Youth 12 and under are free and do not need a membership but must follow all property rules.

No, most of our property listings are available to Infinite Outdoors Members without a pass. If you plan on fishing on a regular basis talk to our support team and see if a pass might make sense.

Not all properties have signs, so be sure to check the property boundaries and information in the Infinite Outdoors app.

Access your adventure on the IO app before heading out the door, all the information and maps will be on the app so you don't need service to navigate your adventure. Also all property maps will download offline onto your app so you can always see where you are on the property, even without service.

We can't guarantee you'll catch fish every time—fishing always comes with a bit of unpredictability due to factors like weather and fish behavior. However, we do everything we can to boost your chances! We offer information on local fly shops so you can get the best tips and gear recommendations. As for the size of the fish, it really depends on where you're fishing. We aim to connect you with spots where you have a good shot at landing some great catches, but it's all part of the Do-It-Yourself fly fishing adventure!
