Low-flow characteristics of Oklahoma streams

Analysis of streamflow records in Oklahoma has provided information on the low-flow characteristics of selected streams in Oklahoma. The 2-, 10- and 20-year low-flow frequency for 1-, 7-, 14- and 30-day durations have been determined for 143 continuous record stations, 46 partial record, and 56 miscellaneous sites in Oklahoma. Low-flows of small uncontrolled streams are zero for the State except for northeastern and south-central Oklahoma.
