1969 Map of Watertown SE

About this map

Big Sioux River meanders southward through the center of this terrain, defining the agricultural landscape of Sheridan Twp and Castlewood in the late 1960s. The southeastern fringe of Watertown is visible in the upper northwest corner, featuring landmarks such as the Harmony Hill High Sch and the Radio Towers (KWAT). This era was marked by the presence of the Chicago and North Western railroad line, which crosses the river valley and passes near the small settlement of Appleby. The topography is dotted with numerous Gravel Pits, signaling the importance of local material extraction for the region's development. Downstream, the river is joined by Willow Creek and flows past the distinct wetlands of Five Ponds, illustrating the natural drainage patterns that shaped the county boundaries between Codington and Hamlin counties.
