1951 Map of Sunken Lake

About this map

Jackson Reservoir dominates the southern landscape of this 1951 survey, a central feature of the irrigation infrastructure developed as part of the Missouri River Basin program. The terrain is defined by complex drainage systems, including Cottonwood Draw and Coal Bank Draw, which channel seasonal water toward the southern basins. Agriculture and water management are the primary drivers of settlement here, evidenced by the Weldon Valley Ditch and the Riverside Canal.
