2021 Map of Long Lake

About this map

Long Lake and several smaller basins define the hydrography of this Cherry County landscape, as documented by the U.S. Geological Survey in 2021. The region is characterized by a series of significant water bodies including South Marsh Lake, Center Lake, and Twentyone Lake, which reflect the hydrology of the Nebraska Sandhills. These lakes are connected by a network of drainage features such as Goose Cr, winding through the low-lying terrain. The map identifies the Sweetwater Valley, a distinct geographical feature that orientations the surrounding wetlands and marshes. This survey provides a precise modern look at the wetland ecosystems and topography of the Sandhills, essential for understanding the environmental shifts in this unique grassland region.
