Oklahoma DroughtWatch

The U.S. Geological Survey Oklahoma Water Science Center continuously monitors the status of surface water in the State's principal rivers, reservoirs, and aquifers. Selected index stations with long-term continuous record spanning many drought periods are used to compare existing streamflows, reservoir storage, and ground-water levels with normal and extreme recorded values. These comparisons...

Oklahoma StreamStats

The U.S. Geological Survey (USGS) periodically publishes streamflow statistics, such as flood-frequency, flow-duration, and mean annual streamflow statistics, for gaged sites with long-term record. Regionalized regression methods recently have been developed for estimating many of these streamflow statistics at ungaged sites as a function of measured physical and climatic drainage basin...
