What You'll Find at Salmon River Reservoir

Salmon River Reservoir is a 2,050-acre impoundment in Oswego County, roughly 30 miles east of Lake Ontario. The lake holds smallmouth bass, lake trout, and landlocked Atlantic salmon, with smallmouth as the most reliable target year-round. The reservoir sits in a rural, forested setting with moderate development along the shoreline—enough public access to fish without feeling crowded, but not so much that you're fishing shoulder-to-shoulder.

The water is relatively clear, particularly in the deeper basins, and the lake's depth profile changes sharply. Shallow bays give way to drop-offs that reach 130 feet in the deepest holes. This structure makes it a different kind of fishing than the shallow, weedy reservoirs elsewhere in the state. You're working with depth and thermocline management, especially in summer.

Access is straightforward: a public boat launch sits at the southern end near the dam, and a smaller launch exists on the northern arm. Both are maintained year-round, though winter conditions can close roads temporarily. Bank fishing is possible in several spots, though the shoreline is steeper than many New York lakes, so wading is limited.

Key Takeaways

  • Smallmouth bass are the primary fishery and bite consistently from May through October, with spring and fall offering the best action in shallower water.
  • Lake trout and landlocked salmon require deeper water and cooler temperatures, making them a summer and fall target when you fish 40 to 80 feet down.
  • The public boat launch at the southern end near the dam is the main access point; a second launch on the northern arm provides an alternative entry.
  • New York fishing licenses and reservoir-specific regulations apply; check the current DEC guide for bass size limits and trout seasons before you go.
  • The reservoir is open year-round, but winter access depends on road conditions and ice safety—call ahead if you're planning a cold-weather trip.

Smallmouth Bass: Spring Through Fall

Smallmouth bass are the workhorse of Salmon River Reservoir. They spawn in April and May in the shallower bays and rocky points, and that's when they bite most aggressively. If you're there in late April or early May, focus on the northern and eastern arms where the water warms first. Depths of 6 to 15 feet hold fish preparing to spawn or already on beds. Jigs, soft plastics, and crankbaits all produce.

By June, the water temperature climbs and fish move deeper, but they don't disappear. Summer smallmouth hold on structure—rocky points, submerged timber, and the edges of drop-offs. Work the 15 to 30-foot zone with finesse presentations: drop-shot rigs, small swimbaits, and tubes. Early morning and late evening are most productive when the sun is low.

Fall is the second-best season. As water cools in September and October, smallmouth move back into shallower feeding zones. They're aggressive and less selective than summer fish. Topwater plugs, crankbaits, and jigs all work. The bite often lasts well into November if the weather stays mild.

Lake Trout and Landlocked Salmon in Deeper Water

Lake trout and landlocked Atlantic salmon are present but require a different approach than smallmouth. Both species prefer cold water and spend most of the year in the deeper basins where the thermocline sits. In summer, they're typically 50 to 100 feet down. You'll need a depth finder to locate them and a willingness to fish vertically or troll at precise depths.

Spring (April through May) and fall (September through November) are the best windows. As water temperatures moderate, trout and salmon move shallower and feed more actively. In spring, they may be 30 to 50 feet down; in fall, similar depths. Live shiners, small spoons, and jigging spoons all work. Trolling with small crankbaits or live bait rigs is also effective if you have a boat.

Winter fishing for trout is possible through the ice, but it requires specific equipment and knowledge of safe ice conditions. The reservoir does freeze, but ice thickness varies by year and location. Check with the DEC or local bait shops before committing to an ice trip.

Seasons and Weather Patterns

Salmon River Reservoir is fishable year-round, but conditions and fish behavior shift dramatically with the seasons. Spring (April through May) brings warming water, spawning activity, and aggressive smallmouth. Water temperatures climb from the low 40s to the mid-50s, and fish move from deep winter haunts into shallower feeding zones.

Summer (June through August) is warm and stable, but the thermocline forms and trout retreat to deep, cool water. Smallmouth fishing requires patience and finesse. The lake can be crowded on weekends, particularly in July and August. Early mornings and late evenings are your best bet for both numbers and size.

Fall (September through November) is arguably the best overall season. Water cools, fish feed aggressively, and the weather is pleasant. Smallmouth bite throughout the day, and trout move into more accessible depths. By late November, the lake begins to freeze, and access becomes weather-dependent.

Winter (December through March) is quiet. The lake freezes solid, and ice fishing is the primary option. Road access to the launch can be compromised by snow, so call ahead. Spring thaw (late March through April) brings high water and runoff, which can affect clarity and fish location.

Regulations and Licensing

You'll need a valid New York State fishing license to fish Salmon River Reservoir. Licenses are available online through the DEC website, at sporting goods stores, and at some bait shops. A one-day license costs less than a full-season license if you're visiting for a single trip.

Bass regulations in New York change periodically, so check the current DEC fishing guide before you go. Typically, smallmouth have a 12-inch minimum size limit with a daily limit of five fish, but this varies by year and region. Lake trout and landlocked salmon have their own size and bag limits, which are also listed in the DEC guide.

The reservoir itself has no special restrictions beyond state-wide rules. No motors are banned, and both gas and electric boats are common. Jet skis are permitted in designated areas. Always carry your license and a copy of the current regulations—DEC staff do patrol the lake.

Boat Launch Details and Access

The primary public launch is at the southern end of the reservoir, near the dam. It's a concrete ramp with parking for roughly 20 vehicles and trailers. The launch is maintained year-round by the town, though winter snow removal can be slow. There's no fee to launch, and facilities include a portable toilet during warmer months.

A second launch exists on the northern arm of the reservoir, providing an alternative entry point if the main launch is crowded or if you're fishing the upper basin. This launch is smaller and less developed but still serviceable for trailered boats. Both launches have adequate depth for most recreational boats, even at lower water levels.

Bank fishing is possible in a few spots, particularly near the dam and along the eastern shoreline, but the steep banks and lack of developed access points make it less convenient than launching a boat. If you don't have a boat, ask at local bait shops about guided services or rental options.

What to Bring and How to Prepare

Bring a depth finder if you own one—it's invaluable for locating structure and understanding the lake's bottom profile. A good topographic map or GPS unit helps you navigate the reservoir and mark productive spots. The lake is large enough that getting lost is possible, especially in fog or low light.

For smallmouth fishing, pack a variety of lures: jigs (1/4 to 1/2 ounce), soft plastics (4 to 6 inches), crankbaits, and topwater plugs. For trout and salmon, bring small spoons, jigging spoons, and live shiners if you can source them locally. A good rod-and-reel combo rated for 6 to 8-pound line works for smallmouth; for trout, consider slightly heavier tackle if you're trolling.

Check the weather forecast before you go. The reservoir is exposed, and wind can build quickly. Spring and fall can bring sudden cold snaps. Wear layers and bring a rain jacket. If you're launching early or staying late, bring a headlamp and extra batteries. Cell service is spotty in some areas, so don't rely on it for navigation.

Frequently Asked Questions

What's the best time of year to fish Salmon River Reservoir?

Spring (April through May) and fall (September through November) are most productive. Smallmouth bite aggressively as water warms in spring and cools in fall. Trout and salmon move into shallower, more fishable depths during these seasons. Summer can be good for smallmouth in early morning and evening, but midday fishing is slow.

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

A boat gives you access to most of the productive water, especially for trout and salmon. Bank fishing is possible in a few spots near the dam and along the eastern shore, but options are limited. If you don't have a boat, check with local bait shops about rental or guide services.

What size fish can I expect to catch?

Smallmouth typically range from 12 to 18 inches, with occasional fish pushing 20 inches. Lake trout average 16 to 22 inches. Landlocked salmon are similar in size. The reservoir produces quality fish, but don't expect trophy-sized catches every trip. Patience and good technique matter more than luck.

Is the reservoir safe to fish in winter?

The lake does freeze, and ice fishing is possible, but ice thickness varies by year and location. Never assume the ice is safe without checking current conditions. Call the DEC or a local bait shop for recent reports before heading out. Wear a life jacket and carry ice safety equipment.

Are there bait shops or services near the reservoir?

Several bait and tackle shops operate in Oswego County and nearby towns. They carry live shiners, crawlers, and tackle, and staff can provide current fishing reports and local knowledge. Search online for shops near the reservoir, or ask at the boat launch—locals often know the best sources.
