Index-gage Data and Regressions in Support of Estimation of Base Flow on Ungaged, Periodically Measured Streams in Small Watersheds in Western Pennsylvania

Streamflow was collected at various streamgages in western Pennsylvania in support of the scientific investigations report "Estimation of Base Flow on Ungaged, Periodically Measured Streams in Small Watersheds in Western Pennsylvania". Data observed at the streamgages for the period of August 1, 2014 through March 31, 2017 are considered. This dataset includes 1) observed streamflow and qualifier indicating the presence of precipitation or runoff at various streamgages, 2) all data used to develop prediction intervals for the titled estimation site based upon the titled index streamgage for use in runoff influenced streamflow analysis, 3) all data used to develop prediction intervals for the titled estimation site based upon the titled index streamgage for streamflow measurement schedule analysis, and 4) all data used to develop prediction intervals for the titled estimation site based upon the titled index streamgage for the period of May 1, 2015 to March 31, 2017 along with evaluation of data observed before May 1, 2015.
