Ohio

Ohio StreamStats is available in Beta Version 3

A beta version of StreamStats version 3 is now available for Ohio. Links to both the version 2 and the beta version 3 applications are provided below. Currently, beta version 3 can only delineate drainage basins, compute basin characteristics, and estimate streamflow statistics using regression equations for user-selected sites; however, it provides several new options for quickly locating (zooming into) sites of interest. Additionally, beta version 3 provides the ability to select which basin characteristics and regression equations will be computed for user-selected sites, whereas version 2 automatically computes all possible basin characteristics and regression equations. Limiting the basin characteristics and regression equations that are computed at once may avoid problems with timing out and receiving only partial results when users select sites with large drainage areas. Beta version 3 also can provide reports of information for USGS data-collection stations. The version 2 application should be used for all other functionality until version 3 can be made fully functional. Links to user instructions for both applications are provided to the left of this page. Although the results provided by the beta version 3 application for Ohio have been fully quality assured, users may experience some user interface performance issues while version 3 development proceeds.

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. Users should familiarize themselves with this report before using StreamStats to obtain estimates of streamflow statistics for ungaged sites.

 

Version 2 Interactive Map

Beta Version 3 Interactive Map

 

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

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.
