2017 Map of Swan Lake

About this map

Swan Lake and a series of glacial depressions define the landscape along the eastern edge of the Coteau des Prairies in this high-plains region. Spanning the boundary between Day and Clark Counties, the map reveals a prairie landscape dominated by water and section-line roads like Main St and Co Rd 30. The presence of Highland Cem and Hosanger Cem indicates the long-standing agricultural communities that have worked this land since the early years of settlement. The cluster of smaller bodies of water, including Mud Lake, Horseshoe Lake, and Long Lake, illustrates the pothole topography characteristic of this part of South Dakota, where the natural drainage patterns create a sanctuary for local wildlife amidst the expansive grid of the Public Land Survey System.
