1 Hydrologic Investigation of the Rush Springs Aquifer in West- Central Oklahoma, 2015 Christopher Neel Assistant Division Chief, Planning and Management Water Resources Geologist Oklahoma Water Resources Board December 6, 2018

2 Purpose and Scope Statutes direct the OWRB to undertake hydrologic studies of aquifers and update major aquifer studies at least every twenty years after the issuance of the final order determining the maximum allowable yield. Studies must consider a minimum of 20- year life of basin when establishing the maximum annual yield Comprehensive Water Plan Directs agency to finish unstudied basins and work on backlog of 20-year updates. Aquifer study goals Define aquifer boundary Determine aquifer base Potentiometric surface map Hydraulic properties of the aquifer Hydraulic conductivity Transmissivity Storativity Analyze permitted groundwater use Climate data Estimate aquifer recharge Estimate base flow contribution to streams Water quality
