About this lake
A small reservoir west of Manitou on the edge of the Pembina Valley, Mary Jane Reservoir is one of the few southern Manitoba waters managed specifically for black crappie, with a dedicated limit of four. Walleye are also present under the southwestern size rule. It is a niche panfish stop for anglers exploring the valley's smaller reservoirs.
