About this map

The Sand Hill River meanders across the central portion of this Polk County landscape, marking the primary natural drainage in a region heavily modified for agriculture. This rural expanse is defined by an extensive network of engineered waterways, including Judicial Ditch Number Fifty-seven and County Ditch Number Seventy-three, which follow the section lines of the Public Land Survey System to manage the low-lying terrain. These ditches illustrate the late 19th and early 20th-century transition of the Red River Valley into a productive farming district.
