Sullivan Lake

Get to know “Sully”.

MN-MapLake Sullivan is one of the larger lakes located in Morrison County near the towns of Hillman and Harding. Near the Crow Wing County line in northeast Morrison County, the lake has a broad connection to Platte Lake via the Platte River.  Much of the lake other than the marshy areas has been developed.  Sand and gravel are the most common shallow water bottom types. The lake supports a diverse aquatic plant community with emergents such as wild rice, hardstem bulrush, and cattails being common on the north half of the lake and bushy pondweed, white-stem pond weed, and water celery being the most common submerged plants throughout the lake. Lake Sullivan also has a variety of fishing structures such as steep drop-offs, points, vegetation islands, weed lines, flats, and sunken bars. The lake supports a diverse fish community that inthat provides plenty of angling opportunities. Good land use practices are employed in the watershed by lakeshore owners to protect and maintain the water quality and fish habitat in the lake.
