Why You Should Visit
Nowhere else in the state can outdoor enthusiasts find a waterway as large as Olin Lake in Lagrange County with barely a hint of human intervention and development. The crystal clear waters are surrounded by trees and dense vegetation, with tamaracks turning the landscape a smoky gold in the autumn months. Come spring, the forest floor is painted with splashes of color by native wildflowers. Whether hiking the 1.5 miles of walking trails or launching your canoe down nearby Oliver Lake, this natural area is a sight to see.
Olin Lake was dedicated as a State Nature Preserve in 1975-6 and 1989. It is owned and managed by the Indiana Division of Nature Preserves. Work done here is in partnership with ACRES Land Trust, Indiana Heritage Trust, and Olin Lake Home Owners Association.
The state-threatened early ladies' tresses and the rare alder buckthorn can be found around Olin Lake. A small, native population of the rare cisco—or lake herring—also inhabits the cool, deep waters. Please be careful of these sensitive species while walking around or boating in Olin Lake.
