About this map

Glacial topography and a high density of small lakes define this portion of Polk County, where the Hill River meanders through a landscape heavily altered by early 20th-century water management. Numerous named basins, such as Syverson Lake, Agnes Lake, and Sawmill Lake, are interspersed with an extensive network of drainage projects including County Ditch Number Fiftynine and County Ditch Number One Hundred Thirteen. These ditches illustrate the historical effort to manage the region's wetlands for agriculture.

For genealogists and local historians, the map is anchored by the settlement of Olga and a series of rural burial grounds that preserve the names of early congregations and families. These include Froen Lutheran Cem, Brandvold Cemetery, Mamre Cem, and Zion Cem. The grid-like road system, featuring 350th Ave SE and Half Mile Rd, connects these community landmarks across the prairie-pothole terrain.
