Lake Ontario is one of the premier freshwater fishing destinations in North America, offering a diverse ecosystem that supports a wide variety of prize fish. As the easternmost of the Great Lakes, it provides unique opportunities for both shore-based anglers and those with access to deep-water boats. Success on these waters requires a basic understanding of fish behavior, seasonal migrations, and the specific gear needed to handle large game fish.
Common Fish Species in Lake Ontario
The lake is most famous for its “big game” salmon and trout, but it also hosts several other popular species. Knowing what you are targeting will help you choose the right equipment and location.
- Chinook (King) Salmon: These are the most sought-after fish in the lake due to their size and fighting ability. They can grow to over 30 pounds and are typically found in deeper waters.
- Coho Salmon: Smaller than Chinooks, Coho are known for being aggressive and acrobatic when hooked. They are often found closer to the surface.
- Rainbow Trout (Steelhead): These fish are prized for their spectacular leaps and high energy. They migrate between the open lake and tributary rivers throughout the year.
- Brown Trout: Lake Ontario holds world-record-sized Brown Trout. They are often found in shallower, warmer waters near the shoreline, especially in the spring.
- Lake Trout: These are native to the lake and prefer the coldest, deepest sections. They are consistent biters and can be caught throughout the summer months.
- Smallmouth Bass and Walleye: While salmon get the most attention, the shallower bays and eastern ends of the lake offer some of the best bass and walleye fishing in the region.
Understanding the Fishing Seasons
Fishing on Lake Ontario changes dramatically with the temperature. Understanding these seasonal shifts is the most important factor in planning a productive trip.
Spring (April to June)
As the ice melts and the shorelines warm up, fish move into the shallower water. This is the best time for shore fishing and small boat angling. Brown trout are particularly active in the murky “color lines” where river water meets the lake. In late spring, salmon begin to move from the southern shores toward the deeper central areas of the lake.
Summer (July to August)
During the heat of the summer, most species move into deeper, cooler water. This is the peak season for trolling. Anglers use specialized equipment to reach depths of 50 to 150 feet. Chinook salmon are the primary target during this time, as they feed heavily to prepare for their autumn migration.
Fall (September to November)
Fall marks the beginning of the salmon and trout spawning runs. Massive numbers of fish congregate at the mouths of rivers like the Salmon River in New York or the Credit River in Ontario. Anglers often find success casting from piers or wading into the tributaries during this period.
Winter (December to March)
While the main lake does not typically freeze over, many of the protected bays and harbors do. This allows for ice fishing, primarily for yellow perch, northern pike, and walleye. Tributary fishing for steelhead also remains popular for those willing to brave the cold.
Essential Gear and Techniques
Because Lake Ontario is so large, the gear used is often more heavy-duty than what is used in smaller inland lakes. Having the right tools ensures you can land large fish without breaking your line.
Trolling Gear: Most successful lake fishing involves trolling with downriggers. These devices use heavy weights to sink your lures to specific depths. Dipsy divers and lead core lines are also common tools used to spread lures away from the boat and reach different water columns.
Lures and Baits: Spoons are the most versatile lure for Lake Ontario, as they mimic the alewives and smelt that salmon eat. Flasher and fly combinations are also highly effective for Chinook salmon, as the rotating flasher creates vibrations that attract fish from a distance. For shore fishing, live bait like minnows or egg sacs are preferred.
Electronics: A high-quality fish finder (sonar) is nearly essential for boat fishing. It helps you locate schools of baitfish and identify the “thermocline,” which is the layer of water where the temperature changes rapidly. Most fish will stay near this layer to remain comfortable.
Top Fishing Locations
Lake Ontario is bordered by New York State to the south and the province of Ontario to the north. Both sides offer excellent access points and professional services.
- Oswego and Pulaski, NY: Known as the salmon capital of the East Coast, this area offers incredible access to both the lake and the famous Salmon River.
- Rochester and Olcott, NY: These areas are famous for spring brown trout fishing and deep-water salmon trolling in the summer.
- Toronto and Port Credit, ON: The western end of the lake provides excellent urban fishing opportunities, with many charters departing directly from the city.
- The Bay of Quinte: Located on the northeastern side, this area is widely considered one of the best walleye fishing spots in the world.
Safety and Regulations
Safety should always be the first priority when fishing on a Great Lake. Lake Ontario is essentially an inland sea, and weather conditions can change in minutes. Always check the marine forecast for wind and wave heights before heading out.
Licenses: You must have a valid fishing license for the jurisdiction you are in. If you cross the invisible border in the middle of the lake, you must have a license for both New York and Ontario. These can be purchased online through the New York Department of Environmental Conservation (DEC) or the Ontario Ministry of Natural Resources.
Catch Limits: There are strict rules regarding how many fish you can keep and the minimum size they must be. These regulations help maintain the population for future years. Always carry a measuring tape and a current copy of the local fishing regulations to ensure you stay within the law.
Hiring a Fishing Charter
For beginners or those without a large boat, hiring a professional charter captain is the most reliable way to catch fish. Charters provide all the necessary gear, bait, and expertise. They understand the current movement of the fish and can teach you the specific techniques required for Lake Ontario. This is often the most cost-effective way to experience the lake if you only plan to fish once or twice a year.
Lake Ontario offers a rewarding experience for any angler willing to learn its patterns. By focusing on the right seasons and using the proper equipment, you can enjoy some of the best freshwater fishing available.
