Lake Ontario is one of the 5 Great Lakes and is located on the border of New York and Ontario, Canada.  Lake Ontario is the eastern-most and smallest in surface area of the Great Lakes, although it exceeds Lake Erie in volume.  Its primary inlet is the Niagra River (from Lake Erie) and primary outlet is the St. Lawrence River.

Lake Ontario and the Lower Niagara feature great fishing for steelhead, chinook salmon, coho salmon, brown trout and lake trout. Lake Ontario is known to have the largest chinook salmon of the Great Lakes.  Western Lake Ontario provides great near-shore chinook fishing starting in late April and lasting through May.  Offshore fishing for chinooks picks up in July and runs through September.  Eighteenmile Creek, which enters Lake Ontario at Olcott Harbor, also gets a strong run of chinooks, starting in mid-October.  Later in October and November, brown trout begin to enter Eighteenmile Creek on spawning runs providing Lake Ontario's best streamside brown trout fishing. Brown trout are available all winter long, in addition to steelhead.
