1968 Map of Gavins Point Dam

About this map

Yankton serves as a focal point on this late-1960s survey, situated along the northern bank of the Missouri River opposite the Nebraska state line. The map highlights the significant infrastructure associated with the Missouri River Basin development, including the Gavins Point National Fish Hatchery and the vast Lewis and Clark Lake formed behind the dam. Civic and religious life is well-documented with the inclusion of the Courthouse, City Hall, Sacred Heart Ch, and several cemeteries such as Aten Cem and Beaver Creek Cem. Across the water in Nebraska, small communities like South Yankton and Aten are connected by a landscape shaped by agricultural precincts like Frankfort Prec and Prec 2. The presence of the Fort Yankton Historic Site and the rural School No 87 provides a window into the regional heritage and the distribution of early education and historical landmarks in the mid-20th century.
