Drainage basin areas for 376 USGS streamgages in West Virginia and adjacent states were delineated digitally. The USGS Watershed Boundary Dataset HUC12 sub-watershed lines were used as outer limits of basins, and heads-up digitizing was used to delineate boundaries from the stream gage to the HUC12 boundary. The USGS National Map was used, as background, to show both contour lines and digital elevation to highlight drainage basin divides, ridges, and valleys. Basins were delineated for (1) all active continuous-flow and crest-stage streamgages, in West Virginia, through water year 2020, (2) selected inactive streamgages, in West Virginia and adjacent states, that were used in the flood-frequency report prepared...
