What You'll Find in Lake Ontario

Lake Ontario is the smallest of the Great Lakes by surface area, but it holds some of the most consistent fishing in New York. The lake sits at the border between New York and Ontario, Canada, and stretches roughly 190 miles east to west. From the New York side, you can fish for Chinook salmon, coho salmon, lake trout, steelhead, and smallmouth bass. The salmon runs are what draw most anglers — they're stocked annually by both New York and Ontario — but the lake also holds wild populations of lake trout and a strong smallmouth fishery in the shallower bays.

The lake's character changes dramatically by season and location. The eastern end near the Oswego River and the Salmon River is the most productive for salmon, especially during spring and fall runs. The western end near Rochester and the Genesee River holds good numbers of smallmouth and lake trout year-round. Water temperature, current, and depth all shift what you'll catch and where you'll find it.

Key Takeaways

  • Chinook and coho salmon dominate the spring and fall, with peak fishing March through May and August through October from New York tributaries and open water.
  • Lake trout and steelhead are present year-round, but steelhead runs peak in spring and fall when they move into rivers and streams.
  • Smallmouth bass fishing is best in the bays and shallower western end, particularly May through October.
  • New York requires a fishing license for anyone 16 and older; salmon and lake trout have specific daily limits and minimum sizes that vary by species.
  • Most productive fishing happens from boats, but shore access exists at state parks, marinas, and river mouths along the entire New York shoreline.

Salmon Runs and the Best Times to Fish

Lake Ontario's salmon fishery is built on stocking. New York stocks roughly 1.5 million Chinook salmon and 500,000 coho salmon annually, with Ontario adding its own numbers. These fish spend two to three years in the lake, growing to 15 to 40 pounds, before returning to spawn. The spring run begins in March and peaks in April and May as fish move toward tributaries. The fall run starts in August and runs through October, with September and early October typically the most intense.

During spring and fall, the Salmon River near Pulaski and the Oswego River are the primary focal points. Both rivers have public access areas, parking, and established fishing zones. Open-water trolling also produces well during these runs — anglers troll the lake's main basin 5 to 15 miles offshore using downriggers and spoons. The Genesee River near Rochester and smaller tributaries like Sodus Bay also see salmon, though in lower numbers than the Salmon and Oswego rivers.

Summer (June through July) is slower for salmon because most fish have already spawned or moved to deeper, cooler water. Winter fishing (November through February) is possible but limited by ice formation and weather; some anglers fish the Oswego River in winter for late-running fish, but conditions are harsh and access can close without notice.

Lake Trout and Steelhead Through the Year

Lake trout live year-round in Lake Ontario's deeper basins and are a consistent target for boat anglers. They prefer water temperatures below 65 degrees Fahrenheit, so they're deepest in summer (40 to 100 feet) and shallower in spring and fall (15 to 40 feet). Trolling with spoons, tube jigs, and live baitfish works best. The central basin and the area east of Oswego hold the most lake trout.

Steelhead are a separate fishery. These are rainbow trout that spend time in the lake and return to rivers to spawn. Spring steelhead runs (March through May) concentrate in the Salmon River, Oswego River, and smaller streams like Sandy Creek and Eighteen Mile Creek. Fall runs (September through November) follow the same rivers. Shore fishing in these rivers during runs is productive and requires less equipment than open-water trolling. Daily limit and size restrictions apply — check the current New York fishing regulations before you go.

Smallmouth Bass in the Bays and Shallows

Lake Ontario's smallmouth bass population has grown steadily over the past two decades. The fish are concentrated in the western and eastern bays — Sodus Bay, Irondequoit Bay, and the shallower areas near the Genesee River mouth. Fishing is best from May through October when water temperatures are between 60 and 75 degrees. Bass average 12 to 16 inches, with fish over 18 inches common in the bays.

Smallmouth respond to jigs, soft plastics, crankbaits, and live crayfish. Early morning and late evening produce better than midday. The bays are accessible from public boat launches and from shore in several locations. Irondequoit Bay has multiple public access points on the Rochester side, and Sodus Bay has launch facilities near the village of Sodus Point. No special license or permit is required beyond the standard New York fishing license.

Access Points and Where to Launch

Public boat launches exist along the entire New York shoreline. Major launch sites include the Oswego Harbor Marina (Oswego), Salmon River Fish Hatchery parking area (Pulaski), Genesee River Marina (Rochester), and Sodus Point Marina (Sodus Point). Most charge a day-use fee ranging from $5 to $15. Launch hours vary — some are open dawn to dusk, others have extended hours. Call ahead or check the marina's website before you arrive.

Shore access is available at several state parks and public areas. Oswego Harbor, Salmon River Fish Hatchery grounds, and Sodus Bay State Park all allow shore fishing. The Oswego River and Salmon River have public fishing areas near their mouths. Parking is usually free at state facilities, though some require a permit. Check New York State Parks website for current hours and any seasonal closures.

If you don't have a boat, charter services operate out of Oswego, Rochester, and Sodus Point. Captains provide tackle, know the current conditions, and can put you on salmon, lake trout, or steelhead depending on the season. Charter trips typically run 6 to 8 hours and cost $400 to $800 for a group of up to four anglers.

Regulations and Licenses

New York requires a fishing license for anyone 16 and older. A one-day license costs less than a full-year license and is available online through the New York Department of Environmental Conservation (DEC) website or at most sporting goods stores. You do not need a separate license to fish in New York waters that border Canada.

Daily limits and size restrictions vary by species. Chinook salmon have a daily limit of two fish with a 24-inch minimum length. Coho salmon have a daily limit of two fish with a 16-inch minimum. Lake trout have a daily limit of five fish with a 15-inch minimum. Steelhead have a daily limit of three fish with a 12-inch minimum. Smallmouth bass have a daily limit of five fish with a 12-inch minimum. These regulations can change year to year — always check the current DEC fishing guide before you fish.

Certain areas have additional restrictions. Some tributaries close to fishing during spawning periods to protect breeding populations. The Salmon River, for example, has seasonal closures and restricted zones. The DEC publishes a detailed guide to Lake Ontario regulations and closures; download it or request a printed copy before your trip.

What to Expect: Weather, Water, and Conditions

Lake Ontario can be rough. It's a large, deep lake with fetch — the distance wind can push water — that creates waves quickly. Spring and fall are the windiest seasons. Boat anglers should check the forecast before launching and be prepared to return to shore if conditions deteriorate. Smaller boats and inexperienced boaters should fish closer to shore or in the bays rather than the open lake.

Water temperature drives fish behavior more than any other factor. In spring, water warms from the low 40s Fahrenheit to the mid-50s, triggering salmon and steelhead runs. By summer, surface water reaches 70 degrees or higher, pushing salmon and lake trout deep. Fall cooling brings fish back to shallower, more fishable depths. Winter ice can form along the shoreline and in bays, but the main lake rarely freezes solid.

Clarity varies by location and season. The eastern end near Oswego tends to be clearer than the western end. Spring runoff from tributaries can cloud the water temporarily. Clearer water often means you need lighter line and more natural lure colors; cloudier water allows brighter colors and heavier tackle.

Frequently Asked Questions

Can I fish Lake Ontario from shore without a boat?

Yes. Shore fishing works well during salmon and steelhead runs in the Salmon River, Oswego River, and smaller tributaries. The bays also allow shore access. Open-lake shore fishing is less productive than boat fishing, but it's free and requires only a license and basic tackle. State parks and public areas along the shoreline have designated fishing zones.

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

Spring (March through May) and fall (August through October) are most productive because salmon and steelhead runs concentrate fish in rivers and near shore. Summer is slower for salmon but good for smallmouth bass in the bays. Winter is possible but difficult due to weather and ice. Your target species determines the best season — salmon in spring and fall, smallmouth May through October, lake trout year-round.

Do I need a boat to catch salmon?

No. During spring and fall runs, shore fishing in the Salmon River and Oswego River produces well. Boats are more effective for open-water trolling and reaching deeper fish, but they're not required. If you don't own a boat, charter services are available, or fish the rivers during spawning runs.

What size fish should I expect to catch?

Chinook salmon average 15 to 25 pounds, with fish over 30 pounds possible. Coho salmon average 8 to 12 pounds. Lake trout average 4 to 8 pounds, with larger fish in deeper water. Steelhead average 6 to 10 pounds. Smallmouth bass average 12 to 16 inches. These are typical sizes; larger and smaller fish occur regularly.

Is Lake Ontario safe to fish in?

Lake Ontario is safe for fishing, but it's a large, deep lake that can develop rough water quickly. Wear a life jacket on boats, check the weather forecast before launching, and stay close to shore if you're inexperienced or in a small boat. The water is cold year-round — even in summer, hypothermia is a risk if you fall in. Respect the lake's size and power.
