Eagle Lake and the surrounding agricultural lowlands of Hancock and Winnebago Counties anchor this 2010 topographic survey. The landscape is defined by the headwaters of the Iowa River, which splits into the West Branch Iowa River and the East Branch Iowa River. These waterways, alongside human-engineered features like Drainage Ditch Number 129, illustrate the intensive drainage efforts required to maintain the region's productive farmland. The area is dotted with small rural communities and historic crossroads, including the settlements of Hayfield, Madison, and Hawley.
