A study of the hydrogeology of the Central Oklahoma aquifer was started in 2008 to provide the Oklahoma Water Resources Board (OWRB) hydrogeologic data and a groundwater flow model that can be used as a tool to help manage the aquifer.
Groundwater level information collected in the state's water well mass measurement program, conducted jointly by the OWRB and USGS since 1950, is used to predit water use trends and future availability of Oklahoma's groundwater supplies.
