Oklahoma Comprehensive Water Plan


Streamflow Conditions

Map of the OWRB/USGS drought monitoring (stream gauge) network

To obtain a fairly representative impact of drought upon the flow of Oklahoma rivers and streams, the U.S. Geological Survey's Oklahoma District and OWRB have selected a network of six existing stream gages across the state (all a part of the network previously established and maintained by the two agencies). Daily discharges are compared with average discharges over the current period of record, corresponding with the beginning of the water year, October 1. The streams are included in the network because they are generally unregulated by upstream reservoirs in Oklahoma and thus more accurately reflect streamflow and runoff conditions. Hydrographs are generated by the USGS on a monthly basis and weekly during times of drought.
