The U.S. Geological Survey Oklahoma Water Science Center and Caddo Nation appreciate the funds provided for this study by the Bureau of Indian Affairs and the Bureau of Reclamation Native American Affairs Technical Assistance Program. The authors also thank the private landowners who provided access to their lands for data collection. Progress on the study could not have been made without the landowners’ cooperation. v Contents Acknowledgments .......................................................................................................................................iii Abstract ..........................................................................................................................................................1 Introduction ....................................................................................................................................................2 Purpose and Scope ......................................................................................................................................2 Study Area Characteristics .........................................................................................................................2 Hydrogeology of the Study Area ................................................................................................................5 Base Flow from the Rush Springs Aquifer ................................................................................................6 Interaction between Groundwater and Surface Water of the Rush Springs Aquifer .....................23 Streambed Hydraulic Conductivity .................................................................................................23 Hydraulic Head in Streams and Alluvium ......................................................................................26 Volumetric Flow Rates from Seepage Meters ..............................................................................28 Interaction between Groundwater and Surface Water at Cobb Creek near the Eakly, Oklahoma, Streamflow-Gaging Station ............................................................................30 Springs Inventory and Location of Wetlands .........................................................................................34 Potentiometric Surface and Regional Groundwater Flow, 2010 .........................................................38 Groundwater-Level Fluctuations, 2010–13 ..............................................................................................41 Summary .......................................................................................................................................................52 References ...................................................................................................................................................53 Figures 1.
