Mann Lakes

The Mann Lakes are two close basin lakes in Alberta. Once a single lake named Mann Lake, the construction of Highway 28 in 1961 split the lake in two. The more southerly Upper Mann Lake lies at 54.14361°N, -111.51583°W, and just north of it, the more northerly Lower Mann Lake at 54.16667°N, -111.5°W. Since 1980, their water level has been steadily declining.
