Statistical summaries of streamflow records through 1984 for gaging stations in Oklahoma and parts of adjacent states are presented in this report. Records are presented for 148 stations with at least 10 years of unregulated or regulated streamflow. Streamflow at 70 of the stations is regulated for certain perdiods. Data for these periods were analyzed separately to account for changes in streamflow due to regulating structures.
For each gaging station, a brief description of the location, drainage area and period of record is given. For those stations with a regulated streamflow record, a brief regulation history is given also. This information is followed by tables of monthly and annual discharge statistics, low- and high-flow frequency statistics, peak-flow frequency statistics, and flow-duration statistics. Daily flow-duration hydrographs are included for most stations.
