Derived from the National Hydrography Dataset's (NHD) Flowlines, this layer represented the network of rivers and streams directly connected to the Great Lakes. Please refer to the process steps and https://glcwra.wim.usgs.gov/ for further explanation on the methods. The surface drainage network connected to Lake Huron is represented with the SBRA 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 -84.2819 -82.4770 44.5433 43.1145 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 hydrology natural resource management water quality remediation wetland ecosystems Holocene Common geographic areas Great Lakes Lake Huron Saginaw Michigan 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 Saginaw Bay 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.

U.S. Geological Survey 20200820 vector and raster digital data http://nhd.usgs.gov/ 24000 Digital 20160630 observed NHD 0407 Identified the location of streams and rivers within the study area. Using ArcGIS Pro 3.0.3, the "NHDFlowline" feature classes for the NHD HUC 0407 and 0408 were clipped to the SBRA study area. The clipped flowline layers were then merged together and flowline segments which were not still connected to Lake Huron were 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 = SBRA 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 = SBRA DEM, Snap Raster = SBRA DEM). The resulting raster represents the final raster dataset for Parameter 3. 20230829 Raster Grid Cell 15480 14078 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 SBRA_P3_Flowlines.tif A raster dataset (in geoTIFF format) representing areas near NHD Flowlines with connection to Lake Huron.
