About this map

Crystal Lake sits at the heart of this agricultural landscape in Hancock County, where the town of the same name borders the southern shore. The map illustrates a highly managed water system essential to Iowa's farming history, defined by the headwaters of several significant drainage networks. The W Br Iowa River and the Boone River originate or flow through this territory, supported by a system of man-made channels such as Drainage Ditch Number 39 and Drainage Ditch Number 114.

Beyond the primary lake, smaller water bodies like Lake George and natural flows including Lindsey Cr and Plum Cr dot the gridded road network. In the southeast, the South 80 Field Airport provides a point of aviation interest in a region otherwise dominated by section-line roads and family-owned acreage. This survey captures the critical intersection of natural river sources and the industrial-scale drainage infrastructure that transformed the regional prairie into productive farmland.
