About this map

Sweetwater Valley serves as a prominent geographic landmark in this portion of the Nebraska Sandhills, where the landscape is defined by an intricate network of wetlands and shallow basins. This modern survey illustrates a topography dominated by the seasonal and permanent hydrology of Goose Cr and the numerous depressions that form locally significant water bodies. These features, ranging from the namesake Big Lake to smaller basins like Durbin Lake and Tate Lake, indicate a delicate environmental balance where the water table meets the surface of the dunes.

The distribution of Pearson Swamp and Vrender Swamp alongside larger open waters like Pony Lake and Dads Lake highlights the region's character as a critical habitat. Highway 83 provides the primary north-south corridor through this sparsely populated terrain, cutting across the section lines of Townships 28 and 29 North. The map preserves the specific hydrographic names of these Nebraska wetlands, which are essential for understanding local grazing patterns and water rights in Cherry County.
