Abstract
The Floyd River basin was studied to provide water-resources. Information for a typical surficial aquifer in northwest Iowa. Data collection included test drilling, water-level measurements, and chemical analyses of surface and ground water. The Floyd River basin drains 961 square miles of highly dissected to gently rolling topography. Major streams generally are flanked by flood plains underlain by uncemented sand and gravel deposits. Most of the basin is directly underlain by glacial drift of Pleistocene age which Is In turn underlain by rocks of Cretaceous age. Sand-and-gravel deposits underlying the major flood plains and in buried bedrock channels within the drift comprise the surficial aquifer.
