1973 Map of Orwell Lake

About this map

The Otter Tail River dominates this mid-1970s landscape, winding through a complex of managed wetlands and reservoirs in Otter Tail County. The hydrology of the region is defined by the Orwell Lake reservoir system and the Orwell Dam, which regulates water flow through the Orwell State Wildlife Management Area. This era shows a clear emphasis on conservation and habitat management, with numerous National Waterfowl Production Areas and the Doran State Wildlife Management Area preserved across the townships of Orwell and Western. Local civic life is anchored by the Western Townhall, while the southern reaches of the quadrangle feature Upper Lightning Lake and the meandering Rabbit River. The map also documents industrial land use through scattered Gravel Pits, often situated near the river valleys where glacial deposits were most accessible.
