What You'll Find at McIntosh Lake

McIntosh Lake sits about 10 miles northeast of Longmont and holds largemouth bass, northern pike, and panfish in a reservoir that runs roughly 400 acres when full. The lake is shallow overall—most of it stays under 30 feet—which keeps the water warm enough for bass to stay active most of the year. Pike were stocked here years ago and have established a self-sustaining population, making this one of the few Front Range reservoirs where you can target both species in the same day.

The lake is open to the public through Colorado Parks and Wildlife, with a boat ramp on the north shore and bank access around much of the perimeter. Fishing pressure is moderate compared to nearby Standley Lake, which means you'll have quieter water and better chances at larger fish during peak season. The surrounding landscape is high plains—short grass, scattered cottonwoods, and open sky—so expect wind in the afternoon and sun exposure all day.

Key Takeaways

  • McIntosh Lake holds largemouth bass and northern pike in shallow, warm water that stays fishable from spring through fall.
  • A boat ramp and bank access make the lake reachable whether you have a motorboat, kayak, or fish from shore.
  • Spring and early summer produce the most consistent bass action; pike bite year-round but peak in fall and winter.
  • Afternoon wind is common, so plan for early morning or evening sessions if you want calm water.

Bass Fishing Strategy and Timing

Largemouth bass at McIntosh respond well to shallow-water presentations because the lake bottom is mostly silt and sand with scattered weeds. In spring (April through May), fish the shoreline breaks and any visible vegetation in 3 to 8 feet of water using crankbaits, spinnerbaits, or soft plastics. Early morning is critical—the first two hours after sunrise produce the most strikes before the wind picks up and the sun climbs high.

Summer (June through August) pushes bass deeper and into any available shade. Fish the deeper holes along the dam and around the boat ramp structure during midday, then return to the shallows at dawn and dusk. Topwater lures work well in low light, especially early morning and overcast days. By late summer, the lake can turn over if it gets too warm; if the bite dies suddenly, wait for cooler nights to reset the water temperature.

Fall (September through October) is often the best time for size. Bass feed aggressively as water cools, and you can catch them throughout the day on crankbaits and swimbaits in 6 to 15 feet of water. Winter fishing is possible but slower; fish the deepest holes and use small jigs or live shiners if you want consistent action.

Northern Pike and How to Target Them

Pike at McIntosh are not as abundant as bass, but they grow large and are less pressured than pike in mountain reservoirs. They prefer cooler water, so fall and winter are prime seasons—October through February produces the most consistent bites. Fish larger lures than you would for bass: 4- to 6-inch swimbaits, large spinnerbaits, and pike-specific crankbaits in the 3- to 4-inch range.

Pike hold in the same shallow zones as bass in spring and fall, but in summer they move to deeper water or suspend near the dam. Early morning and late evening are more productive than midday. If you hook into a pike, expect a hard fight and sharp teeth—use a wire bite leader or heavy fluorocarbon to avoid cut-offs. Many anglers catch pike incidentally while bass fishing; if you want to target them specifically, switch to larger lures and fish slower presentations.

Bank Access and Boat Ramp Details

The main boat ramp is on the north shore and has a paved launch, parking for trailers, and a small fee (typically a few dollars per day, though rates vary). The ramp can get crowded on weekends during summer, so arrive early if you're launching a boat. Bank access is available around much of the lake, though some sections are private property—stick to the public areas near the ramp and along the south shore where access is clearly marked.

If you don't have a boat, kayaking is a solid option. The lake is protected enough for small craft, and you can reach productive shoreline and deeper water that bank anglers cannot. A canoe or small motorboat works well for covering water and reaching the dam structure, where pike and larger bass often hold.

What to Bring and What to Expect

Afternoon wind is nearly may provide from May through September, so plan for it. Bring a windbreaker, secure your hat, and be ready to adjust your casting. The sun is intense at this elevation, so sunscreen and a hat are essential. Water temperature ranges from the low 40s in winter to the mid-70s in summer, so dress in layers and bring a wetsuit if you're kayaking in cold months.

Facilities are minimal—there's a parking area and ramp, but no restrooms or concessions nearby. Bring water, snacks, and any tackle you think you'll need. The lake is open year-round, but access can be limited during heavy snow or ice-out periods in spring. Check Colorado Parks and Wildlife's website or call ahead if you're visiting in late winter or early spring.

Regulations and Licensing

Colorado requires a valid fishing license for anyone 16 and older. You can purchase a license online through Colorado Parks and Wildlife, at sporting goods stores, or at the ramp. Daily bag limits for largemouth bass are typically 15 fish per day with a 12-inch minimum size; pike limits are usually 5 fish per day with an 18-inch minimum. Panfish (bluegill, crappie) have higher bag limits—check the current regulations before you fish, as they can change year to year.

The lake is open to motorboats, but there may be horsepower restrictions—verify current rules with Colorado Parks and Wildlife. No swimming is allowed, and the lake is closed to ice fishing during certain periods to protect pike spawning habitat. Respect posted signs and stay off private property adjacent to the lake.

Frequently Asked Questions

Is McIntosh Lake better than Standley Lake for bass?

McIntosh is shallower and warmer, which can produce more consistent bass action in spring and summer. Standley is larger and deeper, so it holds bigger fish but requires more skill to locate them. Both are worth fishing; McIntosh is often less crowded and easier for beginners.

Can I fish McIntosh in winter?

Yes, but the bite is slower. Pike bite better than bass in cold water, and you'll have more success early morning or late afternoon. Ice fishing is not allowed during certain periods to protect spawning habitat, so check regulations before you go.

What's the best lure for pike at McIntosh?

Large swimbaits (4 to 6 inches), pike-specific crankbaits, and spinnerbaits work well. Pike prefer larger profiles than bass, so don't be afraid to upsize. Fall and winter are the most productive seasons for pike.

Do I need a boat to fish McIntosh?

No. Bank access is available, and kayaking is popular. A boat lets you reach deeper water and the dam structure, but you can catch fish from shore, especially in spring and early summer along the north and south shorelines.

How far is McIntosh Lake from Longmont?

About 10 miles northeast. From downtown Longmont, head north on Main Street, then east on County Road 1. The drive takes roughly 15 to 20 minutes depending on traffic.
