Little Lake is a small lake on the Otonabee River in the city of Peterborough, Ontario, Canada. The lake is in the downtown of the city and is used for fishing, swimming, boating, and for various special events. The lake lies on the water route from Lake Ontario to the Kawartha Lakes. The area around the lake was first settled by Europeans around the start of the 19th century. Steam- and water-powered saw mills were built on the lake and on the river upstream to prepare lumber for shipment overseas. Sawdust and other debris from the mills polluted the lake, killed the fish and clogged up the navigable channels. The smell was so noxious it drove residents near the lake to move. These problems were resolved by the end of the century, when the lake became a hub on the new Trent-Severn Waterway from Lake Ontario to Lake Huron. However, industries attracted by cheap hydroelectric power, such as General Electric used the lake for disposal of industrial chemicals for many years. The pollutants seems to be mostly contained in the sediment, and the lake is now considered safe for recreational use.
The Long Point Region Conservation Area is an agency of the province of Ontario, Canada, formed to preserve the volume of flow, and purity, of the watercourses that flow into Lake Erie, near Long Point.
