Toponymy
At the beginning of the 19th century, Joseph Bureau, among other explorers, described this lake as a very fishy lake, abounding especially pike and trout. Accessibility of La Pêche Lake, near the Ottawa River and Ottawa city, in, favoured sport fishing. The toponym "La Pêche River" was recorded as of December 24, 1976, at the "Bank of place names" in Commission de toponymie du Québec. The toponyms of the lake and river are related together.
History
A grain mill was built in 1838 on the river at MacLaren Falls near Wakefield and is now operated as an inn, the Moulin Wakefield Inn and Spa. A textile mill and a sawmill at the same location helped to provide the impetus for the development of a settlement at Wakefield.
