Water Budget Analysis of the Pawnee Tribe Jurisdictional Area in Payne County, OK

The objective of this proposed project is to construct an annual water budget for the Cimarron River alluvial aquifer between USGS streamgages Cimarron River near Ripley, OK and a proposed new USGS streamgage. Components of the water budget (precipitation, [runoff], evapotranspiration, stream base flow, bedrock lateral flow, and groundwater pumping) will be calculated for the 2017 water year (...
