This shapefile represents the watersheds present within the Crown of the Continent Ecosystem (CCE) boundary.(Note: a different CCE boundary layer was used at the time of creation, so the area amounts within the CCE may not be accurate)This dataset was developed by the Crown Managers Partnership, as part of a transboundary collaborative management initiative for the Crown of the Continent Ecosystem, based on commonly identified management priorities that are relevant at the landscape scale. The CMP is collaborative group of land managers, scientists, and stakeholder in the CCE. For more information on the CMP and its collaborators, programs, and projects please visit: http://crownmanagers.org/

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...

In 2013, the first of several Regional Stream Quality Assessments (RSQA) was done in the Midwest United States. The Midwest Stream Quality Assessment (MSQA) was a collaborative study by the U.S. Geological Survey (USGS) National Water Quality Assessment (NAWQA), the USGS Columbia Environmental Research Center, and the U.S. Environmental Protection Agency (USEPA) National Rivers and Streams Assessment (NRSA). One of the objectives of the RSQA, and thus the MSQA, is to characterize the relationships between water-quality stressors and stream ecology and to determine the relative effects of these stressors on aquatic biota within the streams (U.S. Geological Survey, 2012a). To meet this objective, a framework of fundamental...
