Jock River

The Jock River, known locally as the Mighty Jock, is a river in eastern Ontario that flows through Ottawa and Lanark County. It rises in Montague, crosses the Goodwood Marsh, and empties into the Rideau River north of Manotick. It was named after a Frenchman named Jacques, who drowned in it in the early 19th century. The watershed covers 551 square kilometers. The river is especially well known for its annual spring canoe race, held since 1985 and stretching 12.5 kilometers. The event offers several racing classes and takes advantage of the season's high water levels. A nonprofit organization is also actively involved in protecting the river.
