The North Bay - Mattawa Conservation Authority (NBMCA) was formed under the Conservation Authorities Act of Ontario in 1972 at the request of its 10 member municipalities.
As a community-based, environmental organization in Ontario’s near north, the NBMCA is dedicated to conserving, restoring, developing and managing renewable natural resources on a watershed basis. It is our mission to balance human and economic needs with the needs of the natural environment.
The NBMCA’s area of jurisdiction equals over 2,900 square kilometres and is based on identified watersheds within the Lake Nipissing and the Ottawa River Basins. Highlights of the NBMCA's jurisdictional area include Lake Nipissing, Trout Lake, Wasi Lake, the Mattawa River, the North Bay Escarpment and parts of Algonquin Park.
