Welcome to StreamStats


Beta version 4 has arrived!

Beta version 4 is now available for most states on a trial basis, and version 3 remains available. Beta version 4 provides a single user interface (at for all states that are implemented, rather than separate applications for each state, as in versions 2 and 3, and the user interface is more user friendly than previous versions. Information for user-selected ungaged sites currently cannot be obtained using beta version 4 for the States of Iowa, Indiana, North Carolina, and Oregon because of unique functionality for those states that is not yet implemented. Users are encouraged to provide comments and report bugs by use of the Help button on the interface, which also provides access to limited beta version 4 documentation. See below for additional information about versions both 3 and 4.

Please contact the StreamStats by email at if you have any questions.

With the exception of the report by Koltun and others (2016), the reports below document the regression equations available in StreamStats for Ohio, the methods used to develop the equations and to measure the basin characteristics used in the equations, references to GIS data layers used in the analysis, and the errors associated with the estimates obtained from the equations. The report on the water-use application (Koltun and others, 2016) describes development of the application, the region for which water use data are available, and a brief description on its use and limitations. Users should familiarize themselves with these reports before using StreamStats to obtain estimates of streamflow statistics or water use for ungaged sites.


Interactive Map


General information on the Interactive Map application, as well as specific sources and computation methods for basin characteristics are available here.

Water-use information is available from Streamstats is limited to an area of northeastern Ohio that is approximately bounded by Erie County in the northwest to Belmont County in the southeast. Koltun and others (2016) present a map of the area of availability.

StreamStats outputs report the uncertainty of the estimates for ungaged basins when basin characteristics for selected sites are within the ranges of the basin characteristics for streamgages that were used to develop the regression equations. Errors for basins with basin characteristics that are beyond these bounds are unknown. The applicable ranges of the basin characteristics are provided in the outputs and messages are provided when basin characteristics are outside of the applicable ranges.

StreamStats for Ohio was developed in cooperation with:
Ohio Department of Transportation,
U.S. Department of Transportation,
Federal Highway Administration,
Federal Emergency Management Agency,
Ohio Environmental Protection Agency,
Ohio Water Development Authority, and
Ohio Department of Natural Resources
Muskingum Watershed Conservancy District.
