1951 Map of Sunken Lake

About this map

Jackson Reservoir dominates the southern portion of this high plains landscape, its waters contained by an extensive Dam 4447 and fed by the Riverside Canal. This 1951 survey reveals a region defined by its water management and agricultural infrastructure, where the Valley Ditch runs along the southern edge and numerous windmills dot the sections to the north. Evidence of shifting land use is visible at the Camden Reservoir (Aban'd), while the Pleasant Prairie School serves as a lone civic marker in the northern grasslands. The terrain is deeply scored by various drainages such as Cottonwood Draw and Coal Bank Draw, which channel runoff toward the reservoir. These features, along with a few marked oil wells, highlight the early 1950s reliance on irrigation and natural resource extraction in this corner of Morgan County.
