Upstream Network Trace
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.

StreamStats Application
StreamStatsis 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.
StreamStatsworks 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. TheNewslink in our left-hand menu will provide notices of any new enhancements.
NOTICE: Computational and sequencing issues have been identified in thePeakFQ softwareandBulletin 17C guidelines(B17C) that may result in erroneous flood-frequency estimates under certain circ*mstances. 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 andUSACE HEC-SSP software. Additionally, refined user guidelines may be released with the updated PeakFQ software to help users avoid the circ*mstances 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 for la

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 streamga
