Water resources of Codington and Grant counties, South Dakota
D. S. Hansen
1990, Water-Resources Investigations Report 89-4147
The primary sources of surface water in Codington and Grant Counties are Lakes Kampeska and Pelican and numerous potholes in western Codington County. Seasonal variations in streamflow and lake levels are directly related to seasonal variations in precipitation and evapotranspiration. Dissolved-solids concentrations in water from streams and lakes increase as...
