STREAMSTATS

StreamStats provides access to spatial analytical tools that are useful for
water-resources planning and management, and for engineering and design
purposes. The map-based user interface can be used to delineate drainage areas,
get basin characteristics and estimates of flow statistics, and more. Available
information varies from state to state.

TIME OF TRAVEL BETA APPLICATION



The Time of Travel Beta Application provides rapid estimates of instream travel
times for emergency spill response scenarios.

STREAMSTATS APPLICATION

StreamStats is a Web application that provides access to an assortment of
Geographic Information Systems (GIS) analytical tools that are useful for
water-resources planning and management, and for engineering and design
purposes. The map-based user interface can be used to delineate drainage areas
for user-selected sites on streams, and then get basin characteristics and
estimates of flow statistics for the selected sites anywhere this functionality
is available. StreamStats users also can select the locations of U.S. Geological
Survey data-collection stations, shown as triangles on the StreamStats map, and
get flow statistics and other information for the stations. The types of flow
statistics that are available vary from state to state. A variety of additional
tools are available for discovering information about streams and the activities
along them.

StreamStats works within Web browser software on personal computers and mobile
devices, and is best viewed using the latest versions of Internet Explorer,
Microsoft Edge, Chrome, or Firefox. The browser must allow HTML5 asynchronous
script execution. The application is being continually improved and expanded.
The News link in our left-hand menu will provide notices of any new
enhancements.

 

NOTICE: Computational and sequencing issues have been identified in the PeakFQ
software and Bulletin 17C guidelines (B17C) that may result in erroneous
flood-frequency estimates under certain circumstances. The USGS, in
collaboration with the U.S. Army Corp of Engineers (USACE), is evaluating these
issues and considering updated methods which can be implemented in PeakFQ
and USACE HEC-SSP software. Additionally, refined user guidelines may be
released with the updated PeakFQ software to help users avoid the circumstances
that give rise to computational errors and mitigate their impact.

STREAMSTATS—A QUARTER CENTURY OF DELIVERING WEB-BASED GEOSPATIAL AND HYDROLOGIC
INFORMATION TO THE PUBLIC, AND LESSONS LEARNED

StreamStats is a U.S. Geological Survey (USGS) web application that provides
streamflow statistics, such as the 1-percent annual exceedance probability peak
flow, the mean flow, and the 7-day, 10-year low flow, to the public through a
map-based user interface. These statistics are used in many ways, such as in the
design of roads, bridges, and other structures; in delineation of floodplains

ESTIMATING PEAK-FLOW QUANTILES FOR SELECTED ANNUAL EXCEEDANCE PROBABILITIES IN
ILLINOIS

This report presents the methods, results, and applications of an updated
flood-frequency study for the State of Illinois. This study, which uses data
through September 2017, updates two previous studies that used data through 1999
and 2009, respectively. Flood-frequency estimates are used for a variety of
land-use planning and infrastructure design purposes, including for the
hydraulic design of

EFFECTS OF IMPOUNDMENTS ON SELECTED FLOOD-FREQUENCY AND DAILY MEAN STREAMFLOW
CHARACTERISTICS IN GEORGIA, SOUTH CAROLINA, AND NORTH CAROLINA

The U.S. Geological Survey (USGS) has a long history of working cooperatively
with the South Carolina Department of Transportation to develop methods for
estimating the magnitude and frequency of floods for rural and urban streams
that have minimal to no regulation or tidal influence. As part of those previous
investigations, flood-frequency estimates also have been generated for selected
