What You'll Find at Contoocook Lake

Contoocook Lake sits in Jaffrey, in southern New Hampshire's Monadnock region, and holds largemouth bass, smallmouth bass, pickerel, and sunfish. The lake covers roughly 90 acres and reaches a maximum depth of about 50 feet, with a mix of sandy and rocky bottom that supports both warm-water species and structure-holding fish. The shoreline is partly developed with homes and partly wooded, and the water clarity varies seasonally — clearer in spring and fall, cloudier during summer algae blooms.

Access is straightforward: a public boat launch sits on the north shore off Contoocook Lake Road in Jaffrey, with parking for several vehicles and a small fee (typically a few dollars per day, though rates vary by season). The launch is suitable for small to mid-size boats, canoes, and kayaks. If you fish from shore, the public areas are limited, so boat or canoe access gives you the most water to work.

Key Takeaways

  • Contoocook Lake holds largemouth and smallmouth bass, pickerel, and sunfish across 90 acres in Jaffrey, with a public boat launch on the north shore.
  • Bass fishing peaks in spring (April through May) and fall (September through October), when water temperatures favor active feeding.
  • New Hampshire fishing licenses are required for anyone 16 and older; you can purchase them online or at local sporting goods stores.
  • The lake's rocky structure and weed beds hold fish year-round, but summer algae blooms can reduce visibility and affect where fish congregate.
  • Smallmouth bass have a 12-inch minimum size limit and a 5-fish daily limit; largemouth bass follow the same rules in New Hampshire.

Seasons and When Fish Are Most Active

Spring (April through May) is the strongest season for bass. Water temperatures climb from the low 50s into the 60s, triggering spawning behavior and aggressive feeding. Fish move shallow to rocky points and weed beds, making them easier to locate and catch. Early morning and late afternoon produce the most strikes, though overcast days can keep fish active throughout the day.

Summer (June through August) slows the bite. Water temperatures reach the upper 70s and low 80s, and algae blooms often cloud the water. Bass retreat to deeper structure and the edges of weed beds where cooler water and shade provide relief. Early morning and dusk remain your best windows; midday fishing is typically slow. Pickerel and sunfish remain active in shallow areas even when bass are sluggish.

Fall (September through October) brings a second strong season. Cooling water temperatures drop back into the 60s and 50s, and bass feed heavily in preparation for winter. The same shallow structure that worked in spring becomes productive again. Water clarity usually improves as algae dies back, making sight-fishing and topwater lures effective.

Winter (November through March) is possible but challenging. The lake does not typically freeze solid enough for safe ice fishing, and open-water fishing in cold conditions requires patience. Some anglers target pickerel and sunfish through the ice in late winter if conditions allow, but most fishing pressure occurs during the warmer months.

Bass and Pickerel Techniques That Work Here

Largemouth bass respond well to soft plastics — 4- to 6-inch worms and creature baits worked slowly along weed edges and rocky drop-offs. Jigs tipped with crawfish imitations are effective year-round, especially in spring and fall. Topwater lures produce strikes in early morning and at dusk, particularly during calm conditions when the commotion draws fish from deeper water.

Smallmouth bass in Contoocook Lake favor rocky structure more than largemouths do. Drop-shot rigs with small soft plastics, tube jigs, and live crayfish all produce consistent results. Work the rocky points and the deeper edges of weed beds where smallmouths hunt. Crankbaits that mimic baitfish are effective in spring and fall when fish are actively chasing prey.

Pickerel — a pike relative common in New Hampshire lakes — are aggressive predators that strike larger lures and live baitfish. Spinners, spoons, and small crankbaits all work. Pickerel often lurk in weed beds and along the shoreline, so casting parallel to structure rather than into open water increases your chances.

Regulations and Licensing Requirements

Anyone 16 years old or older must hold a valid New Hampshire fishing license to fish Contoocook Lake. Licenses are available online through the New Hampshire Fish and Game Department website, at sporting goods retailers, and at town clerk offices. A 3-day tourist license is available if you are visiting, or you can purchase an annual resident or non-resident license.

Bass — both largemouth and smallmouth — have a 12-inch minimum size limit and a 5-fish daily limit in New Hampshire. Pickerel have a 15-inch minimum and a 10-fish daily limit. Sunfish have no minimum size and a 30-fish daily limit. These limits are designed to maintain healthy populations and ensure consistent fishing opportunity across seasons.

Catch-and-release fishing is not required, but many anglers practice it to preserve the fishery. If you keep fish, use a cooler with ice to maintain quality, and clean them promptly after returning to shore.

Getting to the Lake and What to Bring

The public boat launch is located at the end of Contoocook Lake Road in Jaffrey, near the intersection with Route 124. From Peterborough (about 10 miles south), take Route 202 north to Route 124 east, then follow signs to the lake. Parking is available at the launch, though it can fill on weekends during peak season. Arrive early if you plan to fish Saturday or Sunday mornings.

Bring a New Hampshire fishing license, a cooler with ice if you plan to keep fish, sunscreen, and water. A depth finder or GPS unit helps locate structure, especially if you are unfamiliar with the lake. If you are launching a boat, check that your trailer lights work and that your boat is registered with the state. A personal flotation device (PFD) is required for all passengers and recommended for the operator as well.

The launch area has no bait shop or rental facility, so bring your own tackle, rods, and bait. The nearest town with supplies is Jaffrey center, about 2 miles away. Plan your trip accordingly if you need to purchase anything before heading to the water.

Structure and Where Fish Hold

Contoocook Lake's most productive areas are the rocky points on the north and east shores, where depth transitions from shallow to 20 to 30 feet occur. These points concentrate both largemouth and smallmouth bass, especially during spring and fall. The weed beds along the southern shore hold pickerel and sunfish, and provide shade and cover for bass during summer.

The deeper basin in the center of the lake (reaching 50 feet) holds fish during summer heat, but is less productive for most anglers because fish are scattered and harder to locate. Focus your effort on the shallower edges and structure rather than open water. Early and late in the day, fish move into shallower areas to feed, making those times more productive than midday.

Nearby Amenities and Other Options

Jaffrey center offers restaurants, a general store, and gas stations within a few miles of the lake. Monadnock State Park, home to Mount Monadnock, is nearby and offers hiking and additional recreation. If Contoocook Lake is crowded or not producing, other New Hampshire lakes in the region — including Nubanusit Lake and Spofford Lake, both within 15 minutes — offer similar species and often lighter fishing pressure.

Camping is available at several private campgrounds in the Monadnock region, and Jaffrey has lodging options ranging from motels to vacation rentals. If you are planning a multi-day fishing trip, basing yourself in Peterborough or Dublin gives you access to several lakes and a wider range of services.

Frequently Asked Questions

Do I need a boat to fish Contoocook Lake?

A boat or canoe gives you access to the most productive structure and deeper water, but shore fishing is possible in limited areas. The public areas along the shore are small, so most anglers launch a boat or kayak to reach the best fishing spots.

What is the best time of day to fish here?

Early morning (sunrise to mid-morning) and late afternoon through dusk are most productive. Fish feed more actively during low-light conditions, especially in summer when midday water temperatures are high.

Can I fish in winter?

Open-water fishing is possible but slow during cold months. The lake does not reliably freeze thick enough for safe ice fishing, so most winter fishing is limited to dedicated anglers willing to fish from a boat in cold conditions.

What size lures and baits work best?

For bass, use 4- to 6-inch soft plastics, jigs, and crankbaits. For pickerel, larger lures (3 to 4 inches) and live baitfish work well. Sunfish respond to small panfish jigs and live insects. Match lure size to the species you are targeting and the water clarity on the day you fish.

Where can I buy a fishing license?

Purchase a license online through the New Hampshire Fish and Game Department website, at sporting goods stores like Cabela's or local shops, or at the Jaffrey town clerk office. Licenses are available as 3-day tourist licenses or annual resident and non-resident options.
