OTT BIOLOGICAL PRESERVE 

Explore the majestic splendor of the Ott Biological Preserve, Calhoun County's "hidden jewel."  This greenspace includes approximately 300 acres of natural habitats that have been shaped extensively by glaciers.  Within the boundaries of the preserve are two spring fed kettle lakes, Brigham Lake and Hall Lake (pictured above), as well as the east edge of Dexter Lake, wet peaty lowlands and dry, sandy uplands.  The uplands include two prominent eskers (glacial ridges), one traveling nearly the length of the property from southwest to northeast.

Because the area is a nature preserve, all natural features, including flora and fauna, are protected.  Activities such as hunting, fishing, flower-picking and firewood cutting are prohibited as are motorized vehicles, with the exception of wheelchairs or other conveyances for disabled persons. 

The preserve is open every day of the year from 8:00 a.m. to 8:00 p.m.
