1967 Map of Wilmert Lake

About this map

The Minnesota-Iowa border region south of Fairmont is defined by a chain of glacial lakes and an extensive network of drainage infrastructure. This 1960s landscape shows the transition from the southern corporate boundary of Fairmont into the agricultural townships of Silver Lake, Tenhassen, and Rolling Green. The map provides detailed soundings and depth curves for prominent water bodies such as Wilmert Lake, North Silver Lake, and Iowa Lake, the latter of which straddles the state line into Emmet and Kossuth counties.
