The Loup River and its tributaries transport moderate amounts of siliceous minerals from the sand hills region of north-central Nebraska to the Platte River near Columbus, Nebr. Predominant chemical characteristics of these waters are a high percentage of silica, moderate hardness, and a low percentage of sodium. The composition of the Loup River water is influenced by the geologic formations through which ground water, a major contributor to the flows of the Loup River branches, has percolated.
Investigation of water quality at or near proposed dam sites in the Loup River basin indicates that if soil and drainage conditions are favorable, the impounded water would be satisfactory for irrigation use.
