Oklahoma DroughtWatch

This map (from USGS's National Drought Watch Web site) shows the 7-day average streamflow conditions in hydrologic units. Thus, the map shows conditions adjusted for this time of the year. The colors represent 7-day average streamflow percentiles for the day of the year. USGS sites having at least 30 years of record are used. The data used to produce this map are provisional and have not been reviewed or edited. They may be subject to significant change.
