Estimated Water Withdrawals in Oklahoma, 2000

The U.S. Geological Survey (USGS) established the National Water-Use Information Program in 1977 to collect uniform, current, and reliable information on water use. The USGS has compiled national estimates every 5 years since 1950. The most recent national water use compilation is for 2000. The data presented here are the result of the 2000 compilation effort for Oklahoma. The Oklahoma Water...
