|Otonabee River (Odoonabii-ziibi)|
The Otonabee River in Peterborough, Ontario
|Length||55 km (34 mi)|
The Otonabee River is a river that runs from Katchewanooka Lake near Lakefield, into the east side of Peterborough, Ontario (as close as 150 m to downtown), through Little Lake and down 30 km into the northwestern side of Rice Lake. The total length of the river is only 55 km, although geographically, it is a continuation of the Trent River, which drains Rice Lake at its eastern end, making the lake a widening of the combined stream. This river is part of the Trent-Severn Waterway. The river is called Odoonabii-ziibi (Tullibee River) in the Ojibwe language.
Some areas of Peterborough along the Otonabee are prone to flooding following heavy rains, such as happened on July 15, 2004 when 240 mm (7.3 in) fell in some locations in under twenty-four hours. Trent University operates its own hydroelectric plant on the river.
Cow Island is located to the west of the mouth of the Otonabee River.
