Streamflow Statistics

The USGS conducts various studies of streamflow statistics for data collected at streamflow-gaging stations. Streamflow statistics for gaged streams and methods for estimating those statistics for ungaged streams are used by water resource planners and managers for designing infrastructure, managing floodplains, and protecting life, property, and aquatic resources. The most recent USGS studies of...

Flood frequency statistics for streamgages and methods for estimating flood frequency statistics at ungaged sites in Alaska and conterminous basins in Canada are presented in U.S. Geological Survey Scientific Investigations Report 2016-5024. This report revised methods for obtaining basin characteristics and regional skew, and presents new streamflow magnitude and frequency statistics for gaged...

Flow duration and low-flow frequency statistics for streamgages and methods for estimating flow-duration and low-flow frequency statistics at ungaged sites in Alaska and conterminous basins in Canada are presented in U.S. Geological Survey Water Resources Investigations Report 2003-4114.
