The StreamStats Program

Idaho

Idaho StreamStats is available in Beta Version 3

A beta version of StreamStats version 3 is now available for Idaho. 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 Idaho have been fully quality assured, users may experience some user interface performance issues while version 3 development proceeds.

Six reports document the regression equations available in StreamStats for Idaho, the errors associated with the estimates, and the methods used to develop the equations and to measure the basin characteristics used in the equations. The last report by Rea and Skinner (2009) includes full metadata descriptions and links to download the geospatial data sets used by StreamStats for Idaho. Users should familiarize themselves with these reports before using StreamStats to obtain estimates of streamflow statistics for ungaged sites.

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

NOTE: Idaho StreamStats can be used to obtain estimates of flow statistics from regression equations for portions of northwestern Utah and northeastern Nevada that drain northward to the Snake River in Idaho. The Idaho regression equations are considered more applicable in this area than the Utah equations. Estimates of flow statistics from the Utah regression equations are not available for this area using the Utah StreamStats application, and StreamStats is not implemented for Nevada. In the Idaho user interface, when the map is zoomed into scales of at least 1:4 million, the areas of Utah and Nevada where estimates of flow statistics can be obtained are not hatched. Hatching appears along all other border areas in those states to indicate that the Idaho regression equations are not applicable there.

StreamStats for Idaho was developed in cooperation with the U.S. Forest Service, the Idaho Transportation Department, the Idaho Department of Environmental Quality, and the Bureau of Reclamation.
