2011 Map of Hagan Lake

About this map

Hagan Lake is the defining geographic landmark within this sparsely populated stretch of the Nebraska Sandhills. This 2011 survey by the U.S. Geological Survey reveals a landscape dominated by internal drainage and high-desert hydrology, where seasonal wetlands and small basins dot the terrain. The map illustrates a network of local roads and unimproved trails that navigate the undulating contours characteristic of Rock County. This specific era of mapping by the U.S. Geological Survey provides an essential record of the region's hydrography and land use before subsequent shifts in agricultural technology or climate patterns might further alter the ephemeral water bodies that sustain the local ecology.
