Tables summarizing daily streamflow data by year are presented for gaging stations in Oklahoma that have at least 5 years of either unregulated or regulated stream-gaging record through September 30, 1974. Separate tables are presented for unregulated and regulated periods of record. These summary tables include: (1) the number of days in each year that the daily discharge was between selected limits (duration tables), (2) the lowest mean daily discharge (frequency tables), (3) the highest mean daily discharge (frequency tables), (4) a monthly duration table for each station with 29 years or more of essentially unregulated record, and (5) statistics of annual discharge. These summaries provide useful information about the quantity, distribution, and variability of streamflow and provide basic data for developing relations for estimating streamflow at sites other than regular stream-gaging sites. This information is also useful in designing bridges, culverts, and other hydraulic structures as well as reservoirs for water supply, flood control, and low-flow regulation.
