Abstract

The Republican River basin in Nebraska includes about 9,710 square miles in the southwestern and south-central parts of the State. The principal sources of ground water in the basin are sand and gravel deposits overlying the Cretaceous bedrock. In the upland parts of the basin, these sands and gravels occur in both Pleistocene deposits and the Ogallala Formation. Along the Republican River valley the sands and gravels occur in undifferentiated Holocene and Pleistocene deposits. Information mapped includes: configuration of the Cretaceous bedrock surface and the configuration of the spring 1977 water table (scale, 1:250,000); and approximate outcrop of Cretaceous bedrock and approximate extent of White River Group (scale 1:1,000,000).
