About this map

The Nebraska Sandhills near the Sheridan and Cherry County border are defined by a vast, intricate network of seasonal and permanent water bodies. At the center of this landscape sits Hog Island, an area of higher ground surrounded by wetlands and a concentration of named basins including Shell Lake and Dads Lake. The map reveals the management of this unique hydrology through features like the Horseshoe Drainage Ditch, which connects the wetland systems east of Horseshoe Meadow.

Surface water dominates the terrain, with family-named features such as Powell Lake, Frye Lake, and Larson Lake indicating the ranching history of the region. Access is limited to sand-track routes like Shell Lake Rd and 138th Trl, highlighting the isolation of these interior ranch lands. The presence of Alkali Lake and Log Cabin Lake near the eastern boundary suggests the varied mineral and historical character of the individual basins in this section of the High Plains.
