Western Lake Erie Restoration Assessment: Degree Flowlines and Culverts Western Lake Erie Restoration Assessment: Degree Flowlines and Culverts
The U.S. Geological Survey (USGS) created geospatial datasets of potential culvert locations along with flowlines connected to southwestern Lake Erie as part of the Western Lake Erie Restoration Assessment (WLERA). The Degree Flowlines and Culverts datasets represent the flowline network and culverts in the WLERA study area. Both datasets will be served in the Great Lakes Wetlands...
Connecting River Systems Restoration Assessment: Dikes Connecting River Systems Restoration Assessment: Dikes
This dataset represents the location of dikes within the Connecting River Systems Restoration Assessment (CRSRA) study area. For more information, see the full data release documentation and the GLCWRA webpage: https://glcwra.wim.usgs.gov/.
Western Lake Erie Restoration Assessment: Composite Model Western Lake Erie Restoration Assessment: Composite Model
This dataset contains all the layers associated with U.S. Geological Survey (USGS) Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) initiative for the Western Lake Erie Restoration Assessment (WLERA) which aims to identify and rank coastal areas with the greatest potential for wetland habitat restoration. Each layer has a unique contribution to the identification of restorable...
Connecting River Systems Restoration Assessment: Degree Flowlines Connecting River Systems Restoration Assessment: Degree Flowlines
The U.S. Geological Survey (USGS) created the Degree Flowlines and Culverts geospatial datasets representing potential culvert locations along with flowlines within the Connecting River Systems Restoration Assessment (CRSRA) study area. Both datasets will be served in the Great Lakes Wetlands Restoration Area mapping application [https://glcwra.wim.usgs.gov/]. The map-based user...

Saginaw Bay Restoration Assessment: Dikes Saginaw Bay Restoration Assessment: Dikes
This dataset represenst the location of dikes within the Saginaw Bay Restoration Assessment (SBRA) study area. An ArcGIS model identified dikes as having a difference in elevation and slope above a certain threshold. If the elevation difference was below a certain threshold, the area was not considered a dike. However, if the difference in elevation between two points was significantly...
Annual End-of-Summer Snow Cover on Glaciers in Alaska and Northwest Canada Annual End-of-Summer Snow Cover on Glaciers in Alaska and Northwest Canada
This dataset contains observations of the distribution of end-of-summer snow cover on approximately 3000 glaciers across Alaska and Northwest Canada. The data are provided as: (1) GeoTIFF rasters indicating the spatial extent of end-of-summer snow cover on each glacier's surface in each year (one raster per glacier per year), and (2) yearly tables with the equilibrium line altitude and...
