Mississagagon Lake is located in the Township of North Frontenac. It has an elevation of 268 metres above sea level. The lake perimeter is 35.2 kilometres and the deepest point is 24 metres.
Mississagagon Lake supports a warm water fishery, in particular; Lake Herring, Yellow Pickerel, Northern Pike, Smallmouth and Largemouth Bass, Yellow Perch, Rock Bass and Pumpkinseed.
Mississagagon Lake Dam is a water control structure that is located at the outlet of Mississagagon Lake.
Mississagagon Lake is managed as a warmwater fishery. The lake herring, a coldwater species, is also a component of this lake, which is indicative of coldwater conditions and reminiscent of the historical lake trout populations. Walleye spawning has been historically documented throughout the lake. Walleye spawn in small numbers at a small number of sites located on the north shore and near small islands in the western portion of the lake, and spawning assessments for walleye in 1987 and 2003 showed that spawning success was low. The lake still struggles to support a self-sustaining population, and has received rehabilitative stocking of walleye for many years. In order to protect the naturally reproducing walleye population and encourage recruitment success, lake levels can not drop once spawning has begun in May. Spawning sites of other species have not been assessed.
There are no known species at risk or significant natural heritage features.
Mississagagon Lake has approximately 127 residential buildings on the lake and at least 3 resorts/marinas. Other than property on islands, there are no boat-access only dwellings on this lake.
