Lake Manitoba and Lake St. Martin Outlet Channels Project

Manitoba Transportation and Infrastructure is proposing the construction and operation of a new permanent flood control management system located in Manitoba. As proposed, the Lake Manitoba and Lake St. Martin Outlet Channels Project would consist of two new diversion channels each approximately 23 kilometres long: the first running northwards from Watchorn Bay on Lake Manitoba to Birch Bay on Lake St. Martin (Lake Manitoba Outlet Channel), and a second running northeast from Lake St. Martin to Lake Winnipeg, south of Willow Point (Lake St. Martin Outlet Channel). The project would also include the construction of two combined bridge and water control structures, a 24-kilovolt distribution line, and the re-alignment and/or construction of provincial highways, municipal roads and three bridge structures.
