Freshwater withdrawal estimates for Oklahoma by source and category. Withdrawal data from ground water and surface water for domestic, commercial and agricultural use.
National Water Information System (NWIS) real-time data on selected ground water sites, ground water level data, site inventory of wells, test holes, drains, springs and excavations and ground water-quality data for the United States.
We applied a groundwater model to simulate effects of groundwater pumping and artificial recharge on surface water in this area. Results show effects of pumping or recharge on streamflow.
