Katchewanooka Lake is one of the Kawartha lakes in south-central Ontario, Canada. It is about 5 miles (8.0 km) long and .5 miles (0.80 km) wide. The Trent Severn Waterway flows through Lake Katchewanooka into the Otonabee River at its outlet just north of Lakefield, continuing southwest through Little Lake in Peterborough and on into Rice Lake.  Lakefield College School lies on the east side of the lake. 
Susanna Moodie, author of Roughing it in the Bush (1852), lived on a farm on the lake in the 1830s. 
Although water levels in this lake and others in the Kawartha Lakes system are controlled to some extent by locks and dams, the lakeshore is vulnerable to flooding during the spring run-off period. 
The Trent–Severn Waterway is a 386-kilometre-long (240 mi) canal route connecting Lake Ontario at Trenton to Georgian Bay, Lake Huron, at Port Severn.

Its scenic, meandering route has been called "one of the finest interconnected systems of navigation in the world".

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.
