2010 Map of Crystal Lake

About this map

Crystal Lake and its namesake settlement define this northern Hancock County landscape, where the town center sits just south of the water's edge. This modern survey illustrates the rural township structure, anchored by the Crystal Lake Post Office and the Crystal Township Cemetery to the west. The terrain is a network of managed water systems, featuring both natural courses like the West Branch Iowa River and engineered waterways such as Drainage Ditch Number 1 and Drainage Ditch Number 114. The map provides a look at the agricultural footprint of the area, including the South 80 Field, and traces the headwaters of the Boone River as it emerges in the southwest. Other natural features include Lake George, Lindsey Creek, and Plum Creek, which navigate the grid of county roads that carve the prairie into precise sections.
