Whitefish Lake is very productive lake with a diverse unique ecosystem. It supports a large population of pickerel, perch and pike fresh water shrimp, crayfish, and dragonfly nymphs.

The Ontario Ministry of Natural resources has said Whitefish Lake is one of the more productive lakes in Ontario in terms of fish produced per acre.

The large beds of wild rice are harvested by First Nation people yielding thousands of pounds of rice annually. The lake has a maximum depth of 20 feet and an average depth of 8 feet. It is surrounded by undeveloped rugged mountain shoreline covered with Boreal forest which displays glorious colour in the fall of the year.

One of North America’s largest colonies of Red Neck Grebes call Whitefish Lake home returning in early spring to herald the beginning of summer. In early June a phenomenal hatch of dragonflies occurs diminishing the population of mosquitoes and black flies.

A host of waterfowl including many species of ducks, Peregrine Falcons, Bittern, Osprey and Bald Eagles nest here in growing numbers.

Castle Creek Provincial Park Nature Reserve is located at the west end of the lake which protects two main features: a cedar stand and shoreline marsh containing calypso orchids.

The shoreline is low density with over 50% of the lake undeveloped owned by the crown. The Whitefish lake area is the gateway to the boundary water canoe area and the entrance to the Northern Lights Corridor encompassing many productive lakes with a myriad of fish species.

Whitefish Lake is located 73 kms southwest of Thunder Bay and 60 kms from the Canada/US Minnesota border.
