Other Information

This natural area protects a variety of riparian habitats on the islands and peninsulas of Upper Mann Lake. It contains: moderately to strongly rolling till substrate; cobble and sand beaches; aquatic vegetation; emergent vegetation such as cattail and bulrush; willow shrublands in low-lying areas and along lakeshore; mixedwood forest of aspen, balsam poplar, birch and white spruce; aspen stands with diverse shrubs; mixed shrublands; reed grass meadows; and an unusual abundance of mature birch.

Upper and Lower Mann Lakes are shallow lakes set in the rolling, wooded country. The lakes were named after Sir Donald Mann (1853-1934), a vice-president of the Canadian Northern Railway Company, which built a rail line close to Upper Mann Lake in the early 1900s. Before the advent of the railway, the lakes were collectively called Island Lake because they became one large lake with a central island when the water level was high [1].

Irregularly Shaped Upper Mann Lake has numerous bays and islands. The lake is moderately developed with further development is mediated by the presence of the Upper Mann Lake Natural Area [2].
