Something of a hidden treasure along the Upper Gunnison, the Lake Fork in the North East San Juan Mountain range is an excellent wild trout fishery.

Not only is it one of the most beautiful stretches of mountain river for fly fishing in all of Colorado, but it also boasts some of the most productive Gold Medal waters in the west.

The waters here are so rich with trout at Lake Fork that the CDOW has stated that it has more than double the number of 14-inch and larger trout to qualify as a Gold Medal fishery.

Here you will find numerous fast riffles and slower sections of pocket water to ply your skills regardless of what style of fly fishing you prefer. 

The waters along Lake Fork can be challenging, but for those anglers that thrive on the challenge will never be disappointed in a trip to this stretch of the Upper Gunnison.

Best of all, if you aren’t finding any luck on Lake Fork (which is unlikely but possible), there are numerous other places along the Gunnison River that are every bit as promising if you don’t mind a bit of a hike or a short drive.

Best Places to Fish the Lake Fork Gunnison River

It’s hard to pick a wrong spot to fish along Lake Fork or the rest of the Gunnison for that matter. Access to the river for Lake Fork is usually accomplished via the campground roads from the highway just outside of Gunnison

You can also hike from San Cristobal Lake Inlet as well if you don’t mind making your way over a little rough country. Watch for private property as you go, and always ask permission from property owners if you happen on private land or a posted sign in your travels.

A lot of anglers find some of the best fishing near Cherry Creek or downriver over Argenta Falls. An advantage to visiting the section of Lake Fork here is that it provides easy access from many of the local resort’s lakeside. 

There are also many campgrounds, RV parks, and cabins you can rent nearby that make fishing the Lake Fork near Blue Mesa Reservoir more of a vacation and less of a wilderness hiking and fishing excursion.

Best Time to Fish the Lake Fork Gunnison River

Right after the runoff in the spring until early fall provides excellent fishing opportunities all along the Lake Fork.

The mayfly hatch in the springtime is your best bet for early prime season fishing, and caddis flies are the best summer hatch by far. Lake Fork also tends to stay pretty quiet throughout the season due to the technical difficulty of fishing the richer stretches of its waters.

Winter fishing can be a bit treacherous along certain stretches, but the year-round supply of midges keeps the fish biting.

The further you are willing to venture into the wilds along Lake Fork through, the higher your chances of success in any season.

Trip Planning Tips

Flights into Denver can be connected to the Gunnison/Crested Butte Regional Airport in Gunnison, so getting to Lake Fork generally isn’t all that difficult or expensive.

If you are a fan of rough living and the great outdoors, there are numerous campgrounds in and around Lake Fork that provide easy access to the river as well.

Similarly, there are many RV parks, regular hotels and motels, and even a lakeside resort nearby that offer varying levels of luxury and comfort depending on your budget.

Check to see what their “offseason” time of year is, and book accordingly. It’s also worth looking into local vacation rentals, as these can yield unexpected bargains regardless of the season as well.
