Water Well Level Mass Measurement Program

Groundwater level information collected in the state's water well measurement program, conducted jointly by the OWRB and USGS since 1950, is used to predict water use trends and future availability of Oklahoma's groundwater supplies. Each year, primarily during the winter months, Board staff measure depth-to-water in approximately 750 wells throughout Oklahoma, including 250 in the Panhandle region. While a primary purpose of data collection is to determine the maximum annual yields of state groundwater basins, the program also helps track water level changes and identify areas experiencing groundwater depletion.
