What to expect at Windsor Lake

Windsor Lake sits in the foothills west of Fort Collins, about 45 minutes from downtown Denver. It's a 70-acre reservoir that holds both rainbow trout and northern pike, making it one of the few Colorado front-range lakes where you can target either species in the same day. The lake is open year-round, though winter access depends on snow conditions on the access road.

The water is coldest from November through March, when pike fishing slows but trout remain active. Spring and fall are the most reliable seasons — water temperatures sit in the 50s and 60s, and both species feed predictably. Summer brings warmer water and more boat traffic, which can push fish deeper during midday hours.

Windsor Lake is managed by the Colorado Parks and Wildlife (CPW) and requires a valid Colorado fishing license. The lake has a boat ramp, picnic areas, and a small parking lot. No gas motors are allowed — only electric trolling motors or hand-propelled boats. This restriction keeps the lake quieter and makes it easier to fish from a kayak or canoe.

Key Takeaways

  • Windsor Lake holds rainbow trout and northern pike year-round, with spring and fall offering the most consistent fishing.
  • Only electric motors or non-motorized boats are permitted, so plan to fish from a kayak, canoe, or small electric-powered vessel.
  • A Colorado fishing license is required; you can purchase one online through the CPW website or at most sporting goods stores in the area.
  • The access road can become impassable in winter, so call ahead or check CPW conditions before driving out in snow.
  • Fish the deeper structure and drop-offs in summer; trout move shallow in spring and fall, and pike hunt near weed beds year-round.

Trout fishing at Windsor Lake

Rainbow trout are the primary trout species here, ranging from 10 to 16 inches on average, with occasional fish pushing 18 inches. They respond well to small spinners, spoons, and soft plastics in the 2- to 3-inch range. Early morning and late afternoon are most productive, especially in spring and fall when water temperatures favor active feeding.

From shore, fish the north and east banks where shallow structure and inlets create feeding zones. From a boat, work the drop-offs on the west side of the lake, where depth transitions from 15 feet to 30 feet. Trout often suspend along these breaks, particularly in summer when surface water warms.

Live bait — small shiners or crawdads — works well if you prefer a stationary approach. Fly fishing is productive in spring and early summer, especially with small nymphs and dry flies during the evening hatch. The lake's no-gas-motor rule makes it ideal for fly fishing from a kayak, where you can cover shallow bays quietly.

Northern pike fishing at Windsor Lake

Northern pike at Windsor Lake typically range from 18 to 28 inches, though fish over 30 inches are caught several times each season. Pike are ambush predators and concentrate around weed beds, submerged logs, and the shallow bays on the north end of the lake. They hunt most actively in spring (April through May) and fall (September through October), when water temperatures sit between 50 and 65 degrees.

Use larger lures — 4- to 6-inch spinners, crankbaits, or soft plastics — to target pike and avoid smaller trout. Cast along weed lines and let the lure pause; pike often strike on the pause or during a slow retrieve. Early morning and overcast days produce better results than bright midday conditions.

Live bait is also effective for pike. A 6- to 8-inch live trout or sucker fished on a quick-strike rig near deep structure will draw strikes. Winter pike fishing can be excellent if you're willing to fish through the cold — pike remain active under the ice, and the lake's smaller size makes it manageable for ice fishing if conditions allow.

Access, parking, and facilities

Windsor Lake is located about 12 miles northwest of Fort Collins. From Fort Collins, take US-287 north, then turn west on County Road 54G. The road is paved but narrow and winding; it climbs into the foothills and can become snow-packed or icy in winter. Check CPW road conditions or call the Fort Collins Parks and Recreation office before heading out in cold months.

The parking area holds about 20 vehicles and fills quickly on weekends. There is a boat ramp suitable for kayaks, canoes, and small electric-motor boats. The ramp is concrete and well-maintained. A picnic area with tables sits near the parking lot, and vault toilets are available. There is no drinking water, fuel, or food service at the lake.

The lake closes at sunset. Day-use only is permitted — no overnight camping. A small day-use fee is charged; check the CPW website for current rates. The lake is open to the public, but access is controlled by a gate that is locked after hours.

Regulations and licensing

A valid Colorado fishing license is required for anyone 16 and older. You can purchase a license online through the CPW website, by phone, or at sporting goods retailers in Fort Collins. A one-day license is available if you're visiting from out of state.

Trout are limited to a daily bag of 10 fish, with a possession limit of 20. Pike have a daily bag of 5 fish, with a possession limit of 10. Only one pike over 24 inches may be kept per day. Check the current CPW fishing regulations before you go, as rules can change seasonally.

Live bait is permitted. Artificial lures and flies are also allowed. No explosives, poisons, or electrofishing equipment are permitted. Catch-and-release is encouraged, especially for pike, which support the fishery and grow slowly in this lake.

Best times to fish Windsor Lake

Spring (April through May) is the most reliable season. Water temperatures warm from the 40s into the 50s and 60s, trout become aggressive, and pike move shallow to spawn. Expect consistent action from shore or boat, and plan for afternoon thunderstorms common to the foothills in May.

Fall (September through October) is equally productive. Water cools back into the 50s and 60s, both species feed heavily before winter, and crowds thin compared to summer. The weather is stable, and early morning fogs often clear by mid-morning.

Summer (June through August) can be productive early and late in the day, but midday fishing slows as trout and pike move deeper to escape warm surface water. The lake sees more boat traffic and day-use visitors, making it noisier. Winter (November through March) is quiet and can be excellent for trout, but access is weather-dependent and pike fishing slows significantly.

What to bring and how to prepare

Bring a Colorado fishing license, a valid photo ID, and your fishing gear. If you're launching a kayak or canoe, bring a personal flotation device (PFD) — Colorado law requires one for each person in a non-motorized boat. A small cooler with water and snacks is useful; there are no services at the lake.

Dress in layers, especially in spring and fall. Foothills weather changes quickly, and afternoon wind can make the lake choppy. Bring sunscreen and a hat — the high elevation (around 6,500 feet) means stronger UV exposure. If you're fishing in winter, bring extra warm clothing and check road conditions before driving.

A fish finder is helpful if you're fishing from a boat, but not necessary. The lake is small enough that you can locate structure visually or by casting systematically. Polarized sunglasses help you spot fish in shallow water and read the water's surface for feeding activity.

Frequently Asked Questions

Can I fish Windsor Lake in winter?

Yes, but access depends on snow and road conditions. The access road can become impassable after heavy snow. Call the Fort Collins Parks and Recreation office or check the CPW website for current conditions before driving out. Winter pike fishing is slow, but trout remain active under the ice if you're interested in ice fishing.

Do I need a boat to fish Windsor Lake?

No. The north and east shores have good access for shore fishing, and you can reach productive water from the bank. A kayak or canoe is useful for reaching deeper structure and weed beds, but not required. Electric trolling motors are permitted if you have a small boat.

What's the difference between rainbow trout and pike at this lake?

Rainbow trout are smaller (10 to 16 inches average), feed on small insects and baitfish, and respond to spinners and flies. Pike are larger (18 to 28 inches average), are ambush predators, and require bigger lures. You can target both in the same day by using different lure sizes and fishing different areas.

Is there a size limit on trout or pike?

Trout have no minimum size limit. Pike must be at least 15 inches to keep, and only one pike over 24 inches may be kept per day. Check the current CPW regulations, as rules can change seasonally or by water body.

How far is Windsor Lake from Denver?

Windsor Lake is about 45 minutes to an hour north of downtown Denver, depending on traffic. From Denver, take I-25 north toward Fort Collins, then follow the directions from Fort Collins (about 12 miles northwest on County Road 54G).
