Welcome to StreamStats



Please help us conserve our server system resources and close the Interactive Map window when you are finished using it. Doing so will help ensure system availability for all users. Thank you.

Note that the User Instructions for this application include discussions of some tools for network navigation and estimating flows based on similar streamgages that are not yet implemented for Oklahoma. It is planned to add these tools in the future.

Also, please bookmark this page, rather than the Interactive Map page, since the URL for the interactive map may change in the future.

We want your feedback! Please send any comments or questions that you have on StreamStats to the StreamStats development team at GS-W

Oklahoma StreamStats incorporates statewide regression equations for estimating instantaneous peak flows with annual exceedance probabilities of 50, 20, 10, 4, 2, 1, and 0.2 percent. These peak flows have recurrence intervals of 2, 5, 10, 25, 50, 100, and 500 years, respectively. Oklahoma StreamStats also incorporates regional regression equations for estimating the mean annual flow and annual and monthly flow exceeded 20, 50, 80, 90, and 95 percent of the time. The reports below document the regression equations, the methods used to develop them and to measure the basin characteristics used in the equations, and the errors associated with the estimates obtained from the equations. Users should familiarize themselves with these reports before using StreamStats to obtain estimates of flows for ungaged sites in drainage basins.
