Derived from the National Hydrography Dataset's (NHD) Flowlines, this layer represented the network of rivers and streams directly connected to the Great Lakes. For more information, see the full data release documentation and the GLCWRA webpage: https://glcwra.wim.usgs.gov/. The surface drainage network connected to the Great Lakes is represented with the CRSRA flowlines dataset. This parameter was necessary because land areas connected to the lakes via streams or other water features are better suited for wetland restoration. The purpose for releasing version 2.0 of these datasets is that they were created with more recent and more accurate input data. For changes between versions 1.0 and 2.0, please see the Release History text file. 2024 publication date Complete None planned -83.3918 -82.3643 43.2349 42.0117 ISO 19115 Topic Category environment geoscientificInformation inlandWaters Marine Realms Information Bank (MRIB) keywords lake lakeshore wetland wetland restoration stream river hydrology resource management USGS Thesaurus natural resource management water quality remediation wetland ecosystems Temporal Holocene Common geographic areas Great Lakes Lake Huron Lake Erie Lake St. Clair St. Clair St. Clair-Detroit None.

Ann Arbor MI 48105 US 734-214-9308 734-994-8780 kkowalski@usgs.gov The GLCWRA was produced with funding provided by the Great Lakes Restoration Initiative (GLRI) and in collaboration with the New College of Florida. Digital datasets obtained from public repositories and datasets including the National Hydrography Dataset (NHD), National Wetland Index (NWI), 3D Elevation Program (3DEP), U.S. Census Bureau, National Geospatial Program, U.S. Fish and Wildlife Service, National Oceanic and Atmospheric Association (NOAA), Protected Areas Database of the U.S. (PAD-US), National Land Cover Database (NLDC), Gridded Soil Survey Geographic Database (gSSURGO), Coastal Change Analysis Program (C-CAP) U.S. Geological Survey 2016 application/service Geonarrative map website for GLCWRA study https://glcwra.wim.usgs.gov/ The attribute values of this dataset were inspected and confirmed to be within the proper range of values. The attribute values were reviewed, and spatial data was visually inspected to verify the that the data values and their locations accurately describe the purpose of the data. This dataset is considered complete for the information presented, as described in the abstract. This dataset provides coverage for the entire Connecting River Systems Restoration Assessment study area. Approximately 20% of the spatial data was visually inspected to verify the positional accuracy of its features. The review consisted of comparing the spatial data to its input datasets and to underlying GIS basemaps. While this data has been reviewed, the spatial data is only as spatially accurate as the input data sources. This dataset does not have a vertical component, so testing for vertical accuracy was not necessary.

Using ArcGIS Pro 3.0.3, the "NHDFlowline" feature classes for the NHD HUC 0408, 0409, and 0410 were clipped to the CRSRA study area. The clipped flowline layers were then merged together and flowline segments which were over the St. Clair and Detroit Rivers and Lake St. Clair were manually deleted. 20230828 The remaining NHD flowline segments were buffered by 30 meters using the 'Buffer' tool (Side Type = Full, End Type = Round, Method = Planar, Dissolve Type = Dissolve all output features into a single feature). Then using the 'Polygon to Raster' tool, the buffered NHD flowline segments were converted into a raster Tiff file (Cell assignment type = Cell Center, Priority field = NONE, Cellsize = 10 meter, Snap Raster = CRSRA DEM). 20230829 Finally, the raster provided in the previous step was reclassified using the 'Reclassify' tool where all cells representing the NHD buffered flowlines were set to '1' and all the other NODATA cells were set to '0' (Mask = CRSRA DEM, Snap Raster = CRSRA DEM). The resulting raster represents the final raster dataset for Parameter 3. 20230829 Raster Grid Cell 13411 8132 1 Universal Transverse Mercator 17 0.9996 -81.0 0.0 500000.0 0.0 row and column 10.0 10.0 meters North_American_Datum_1983 GRS 1980 6378137.0 298.2572221010042 CRSRA_P3_Flowlines.tif Raster layer (TIFF format) that represents the flowlines in the CRSRA, defined by the National Hydrography Dataset.
