About Lake Fork of the Gunnison River

The Lake Fork of the Gunnison drains the northeast San Juans out of Lake City and runs roughly 25 miles down to the Lake Fork arm of Blue Mesa Reservoir. It comes off the flanks of Slumgullion and the high peaks, pools briefly in Lake San Cristobal — a natural landslide-dammed lake just south of town — then drops through town and into a chain of BLM canyon water where the fishing gets serious. Wild browns run the show here: streamborn, thick, and the reason the river fishes as well as it does. Rainbows are catch-and-release in the flies-only water, cutthroat hang in the upper reaches above Sherman, and a few brookies mix in. Fish average 10-16 inches with a real shot at something in the high teens or low twenties down in the canyon.

One thing to get straight, because the marketing muddies it: this is not Gold Medal water. You'll see "Gold Medal" thrown around on shop pages and trip write-ups, and it's true that old Division of Wildlife surveys counted more than the 14-inch-plus fish you'd need to clear the bar — but the Lake Fork never made Colorado Parks & Wildlife's official Gold Medal list. CPW designates it a Quality Water and manages it under Wild Trout special regs. The Gold Medal water in this basin is the Black Canyon and Gunnison Gorge downstream, not the Lake Fork. It's a very good wild-brown fishery on its own honest terms; it just isn't the thing the brochures claim.

It's a wade fishery, full stop — no floating — and about 14 miles of the lower river is public BLM ground reached off the west side of CO-149 through a chain of campgrounds and pullouts. You park, walk down, and fish pocket water and plunge pools with a 9-foot 5-weight. Nymphing produces year-round — RS2s, zebra midges, pheasant tails, San Juan worms, and micro eggs in #14-20 — and the dry-fly fishing turns on once runoff drops out and holds through fall. The catch is runoff itself: the Lake Fork peaks at 1,200-1,400 CFS during snowmelt and stays blown out and unwadeable for a four-to-six-week stretch, so the practical season runs mid-July through late October. Ideal wading flow is roughly 150-300 CFS; over 400 it gets pushy and genuinely dangerous. Lake City is remote — a small mountain town at 8,600 feet, better than an hour from Montrose and well off any interstate — and the two local shops don't publish daily river reports, so you're reading the Gateview gauge yourself or calling ahead. The upside of all that remoteness is pressure: outside the summer campground crowd, the canyon fishes quiet, and the fall brown window rewards anglers willing to make the drive.

Species

  • Brown Trout
    Primary · Sep-Oct (pre-spawn) · 10-16", some to 20"+

    The dominant fish and the reason the river fishes as well as it does — wild and streamborn. In the flies-only canyon sections browns carry a 16-inch minimum and a 2-fish bag. Streamers earn the biggest fish in the fall pre-spawn; nymphs produce year-round.

  • Rainbow Trout
    Common · Jul-Oct · 10-16", some larger

    Catch-and-release in the flies-only Quality Water sections. Best once runoff drops and dry-fly fishing opens up post-July.

  • Cutthroat Trout
    Present · Summer · 8-14"

    Holds in the upper river; the headwaters above the waterfall at Sherman are artificial-only with all cutthroat catch-and-release.

  • Brook Trout
    Sparse · Summer · 6-11"

    A few brookies mix into the upper and tributary water per CPW and local surveys — not a mainstem target.

  • Kokanee Salmon
    Seasonal · Sep-Dec (fall run) · 12-16"

    Run up the lower river out of Blue Mesa in fall. A legal snagging season is open Sep 1-Dec 31 from Argenta Falls down to the reservoir — a regulatory quirk and a fall presence, not a fly target.

Sections

3 reaches

Gateview to Blue Mesa Reservoir

WadeSalmon · Brown Trout · Rainbow Trout

Lower-gradient water where the canyon opens toward the Lake Fork arm of Blue Mesa and the river takes on reservoir influence. Below the Gateview gauge down to the reservoir inlet.

Best for: Brown trout and rainbow trout, plus the fall kokanee salmon run pushing up out of Blue Mesa (snagging season Sep 1-Dec 31, Argenta Falls to the reservoir).

The Canyon / BLM Public Water (High Bridge Gulch to Gateview)

WadeBrown Trout · Rainbow Trout

The signature stretch — freestone pocket water, plunge pools, and boulder runs dropping through a BLM canyon with the best trout density and the biggest fish. Roughly 14 miles of public BLM access off the west side of CO-149 through a chain of campgrounds and pullouts (High Bridge Gulch, The Gate, Gateview, Red Bridge). Wading gets serious above 400 CFS.

Best for: Wild brown trout on streamers in fall and nymphs year-round, with catch-and-release rainbow trout and a strong dry-fly window after runoff drops.

Lake City / Upper Wild Trout

WadeCutthroat · Brown Trout · Rainbow Trout

Smaller, higher-gradient water right out of Lake San Cristobal — pocket water and runs through and just below town at about 8,600 feet. A mix of public and private ground, so mind the boundaries near town. Flies-only from the San Cristobal inlet upstream to the first bridge crossing.

Best for: Wild brown trout and rainbow trout on nymphs and dry-dropper rigs, with cutthroat trout up higher toward the headwaters.

Best seasons

The practical season runs mid-July through late October. Spring runoff (late May into early-to-mid July) peaks at 1,200-1,400 CFS and leaves the river blown out and unwadeable for a four-to-six-week window — the dead stretch. Best of the year is fall (Sep-Oct): brown pre-spawn aggression, BWO hatches, kokanee pushing up from Blue Mesa, and low pressure. Mid-to-late summer (mid-Jul-Aug) brings post-runoff dry-fly fishing with caddis, PMDs, and green drakes. Winter fishes on open water with midge nymphing. Ideal wading is 150-300 CFS; over 400 CFS wading becomes extremely difficult and unsafe.

Regulations

Colorado Parks & Wildlife manages the Lake Fork as a Quality Water under Wild Trout special regs, with section-specific rules along the river. It is NOT on CPW's official Gold Medal list despite frequent marketing to the contrary. A Colorado fishing license is required.

  • Headwaters downstream to the waterfall at Sherman: artificial flies and lures only; all cutthroat trout catch-and-release.
  • Lake San Cristobal inlet upstream to the first bridge crossing: artificial flies only.
  • High Bridge Gulch down to the BLM boundary below The Gate Campground, and Cherry Creek to the upper Red Bridge Campground boundary: artificial flies and lures only; brown trout 2-fish bag with a 16-inch minimum; all rainbow trout catch-and-release.
  • BLM boundary below The Gate down to the Cherry Creek confluence: trout bag and possession limit of 2 fish.
  • Argenta Falls downstream to Blue Mesa Reservoir: kokanee salmon snagging permitted Sep 1-Dec 31.
  • A Colorado resident or nonresident fishing license is required.

Regulations are section-specific and change annually — verify against the current CPW fishing brochure and the body-of-water page before a trip. Despite widespread 'Gold Medal' marketing, CPW's official designation for the Lake Fork is Quality Water / Wild Trout; the basin's Gold Medal water is the Black Canyon / Gunnison Gorge.

Getting there

Lake City, CO

~1.5 hrs from Montrose (MTJ airport), ~55 miles from Gunnison, ~5.5 hrs from Denver

Fly shops

  • Dan's Fly ShopLake City
  • The Sportsman Outdoors & Fly ShopLake City
  • Montrose AnglersMontrose

Camping: Numerous BLM campgrounds line the lower river — The Gate, Gateview, and Red Bridge — and make the canyon water walk-in easy. Town lodging and services in Lake City (seasonal, 8,600 ft); Montrose (~1.5 hrs) has the nearest larger-town services and regional airport.

About 14 miles of the lower river is public BLM ground off the west side of CO-149, reached through a chain of campgrounds and pullouts (High Bridge Gulch, The Gate, Gateview, Red Bridge) — park and walk down to fish. The water in and around Lake City is a mix of public and private, so mind boundaries near town. The two Lake City shops run guides and shuttles but do not publish daily online river reports; read the Gateview gauge or call ahead.
