What You'll Find at Turquoise Lake

Turquoise Lake sits at 9,300 feet in the Sawatch Range near Leadville, Colorado, and holds cutthroat trout and kokanee salmon. The lake spans roughly 1,200 acres and is fed by snowmelt from surrounding peaks, which keeps the water cold and clear through summer. Access is straightforward—a paved road runs along the western shore, and multiple pullouts and a developed campground make it easy to fish from shore or launch a boat.

The cutthroat population here is robust and willing. Fish average 10 to 14 inches, with occasional larger specimens in the 16-inch range. Kokanee are present but less predictable; they school deeper and require more specific techniques. The lake's high elevation means a shorter season—ice-out typically occurs in late May or early June, and the lake can freeze again by October, though September and early October often bring excellent fishing as water temperatures drop.

Key Takeaways

  • Turquoise Lake holds cutthroat trout and kokanee salmon at 9,300 feet elevation near Leadville, with cutthroats being the more reliable target.
  • The fishing season runs from late May through September, with peak conditions in July and August when water temperatures stabilize.
  • Shore fishing is productive along the western access road; boat anglers can reach deeper water and kokanee more consistently.
  • Colorado Parks and Wildlife requires a valid fishing license and enforces a daily limit of 10 cutthroat trout per person.
  • The lake sits within the San Isabel National Forest, and camping, parking, and boat launch facilities are maintained year-round.

Seasons and Water Conditions

Turquoise Lake's season is compressed by its elevation. Snowmelt typically clears the ice by late May, but water temperatures remain in the 40s through June. Cutthroats bite during this period, but action accelerates in July when the lake warms into the 50s and 60s. August is peak season—water is warmest, fish are most active, and weather is most stable. By September, temperatures drop again, which can trigger aggressive feeding as fish prepare for winter.

Fall fishing from late August through mid-September is often overlooked but productive. Fewer anglers are present, water clarity is excellent, and cutthroats feed more aggressively in cooling water. October is possible but risky; snow can arrive early, and the lake can begin to freeze. Winter access is limited—the campground closes, and the road is not always plowed, though locals do fish through ice in some years.

How to Fish Turquoise Lake

Shore fishing works well along the western access road. Cutthroats respond to small spinners (size 0 to 1), spoons, and soft plastics in natural colors—olive, brown, and silver. Fly anglers do well with small nymphs and streamers, particularly in early morning and late evening. Cast parallel to shore in 8 to 15 feet of water; cutthroats often hold near drop-offs and submerged structure.

Boat anglers have an advantage for kokanee, which school in deeper water (30 to 60 feet) mid-lake. Trolling small spoons and jigging with vertical presentations works best. Cutthroats are also accessible by boat; troll the shallower edges or cast near rocky points. A small aluminum boat or canoe is sufficient; the lake is protected from major wind by surrounding peaks, though afternoon breezes can pick up in summer.

Bait fishing with small shiners or worms is legal and effective for cutthroats but is less common than lure fishing. Check current regulations before using live bait, as rules can change. Early morning and the hour before sunset are most productive; midday fishing is slower, especially in July and August when sun intensity is high.

Access, Parking, and Facilities

Turquoise Lake is accessed via County Road 9, which branches east from Highway 24 near Leadville. The road is paved and well-maintained through the fishing season. Multiple pullouts line the western shore, and parking is free. The Turquoise Lake Campground, operated by the U.S. Forest Service, offers 27 sites with vault toilets and water (when open). Camping costs roughly $20 to $25 per night; the campground typically opens in late May and closes in September.

A boat launch is located near the campground and is maintained throughout the season. No motorized boats are permitted on Turquoise Lake, so anglers use canoes, kayaks, rafts, or non-motorized rowboats. This restriction keeps the lake quiet and makes it accessible to paddlers and small-boat anglers. Leadville, about 15 miles away, has gas, groceries, and lodging if you prefer not to camp.

Regulations and Licensing

Colorado Parks and Wildlife manages Turquoise Lake. A valid Colorado fishing license is required for anyone 16 and older. Licenses are available online through the CPW website, at sporting goods stores in Leadville, or at ranger stations. The daily limit for cutthroat trout is 10 fish per person, with a possession limit of 20. Kokanee have the same 10-fish daily limit.

The lake is within the San Isabel National Forest, so no special forest pass is required for day use, though parking at some trailheads nearby does require a Northwest Forest Pass. Check current CPW regulations before your trip, as rules can change. Turquoise Lake has no special restrictions beyond standard Colorado regulations, but it is worth confirming the current status of the campground and road access before traveling, especially in shoulder seasons.

What Makes Turquoise Lake Different

Turquoise Lake's appeal lies in its accessibility and consistent cutthroat fishing at high elevation. Unlike many alpine lakes that require a hike, Turquoise is reachable by car and offers developed camping and parking. The cutthroat population is stable and receptive to simple techniques, making it a good choice for anglers who want reliable action without technical fly fishing or deep-water jigging skills.

The lake's no-motorboat rule preserves a quieter experience and makes it attractive to paddlers and anglers seeking solitude. The surrounding peaks and forest create a scenic setting, and the short season concentrates fishing pressure into a few months, which can mean less crowding than lower-elevation lakes. If you're based in or traveling through the Leadville area, Turquoise Lake is a logical choice for a half-day or full-day outing.

Nearby Alternatives

If Turquoise Lake is full or conditions are poor, several other options sit within an hour's drive. Twin Lakes, also near Leadville, is larger and holds lake trout and cutthroats; it allows motorboats and has more developed facilities. Halfmoon Lake is smaller and higher (10,000 feet) but offers solitude and good cutthroat fishing. Clear Creek Reservoir, to the north, is lower in elevation and warms faster in spring, making it a good early-season option.

The Arkansas River, which flows through Leadville, offers stream fishing for cutthroats and browns. It requires wading and is best in June and September when water levels are manageable. For anglers willing to hike, the high lakes in the Collegiate Peaks Wilderness (accessible from trailheads near Turquoise Lake) hold cutthroats and offer backcountry fishing, though they require a full day or overnight trip.

Frequently Asked Questions

What's the best time of year to fish Turquoise Lake?

July and August offer the warmest water and most consistent action, but September is often overlooked and can be excellent as fish feed aggressively in cooling water. June is fishable but slower; water is still cold. October is risky due to early snow and ice formation.

Can I fish from shore, or do I need a boat?

Shore fishing is productive and requires no boat. Cast from the pullouts along the western access road into 8 to 15 feet of water. A boat gives you access to deeper water and kokanee, but it's not necessary for cutthroat fishing.

Are there restrictions on boat types?

Motorized boats are not permitted. Canoes, kayaks, rafts, and non-motorized rowboats are allowed. This keeps the lake quiet and makes it accessible to paddlers.

What should I bring for high-altitude fishing?

Bring layers—temperature swings are sharp at 9,300 feet, and mornings are cold even in summer. Sunscreen and a hat are essential due to intense UV exposure at elevation. A headlamp is useful for early-morning and evening fishing.

Is the campground open year-round?

The Turquoise Lake Campground typically opens in late May and closes in September. Day-use parking is available year-round, but facilities are not maintained in winter. Call the San Isabel National Forest office to confirm current opening dates before traveling.
