Geological Survey https://doi.org/10.5066/P9UAA4HY The US Geological Survey (USGS) created the Flowlines 10-meter raster dataset as the third parameter in the Western Lake Erie Restoration Assessment (WLERA) which covers the southwestern shore of Lake Erie. WLERA is a part of the USGS's Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) initiative where coastal areas around the Great Lakes are identified and ranked for potential wetland restoration. Derived from the National Hydrography Dataset's (NHD) Flowlines, this layer represents the network of rivers and streams directly connected to southwestern Lake Erie. Please refer to the process steps and https://glcwra.wim.usgs.gov/ for further explanation on the methods. Version 2.0 of this dataset was created with more recently released input data. For information on the changes between versions 1.0 and 2.0, please see the Release History text file. The surface drainage network connected to southwestern Lake Erie is represented with the WLERA 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 datasets in WLERA Composite 2024 (Jaenicke et al., 2024) were created with more recently published datasets than the WLERA Composite 2016 release (Saarinen, 2016). The foremost among these is the digital elevation model (DEM) which was used to create the study area boundary, the hydroperiod, the dikes and the index composite layers. The elevation data was created from 3DEP DEM tiles published between 2015 and 2019. Updated versions of the following datasets were also used in the creation of WLERA Composite 2024: National Wetland Inventory (NWI) data published in 2023, National Oceanic and Atmospheric Association (NOAA) water level measurements from 1993-2023, Soil Survey Geographic Database (SSURGO) data published in 2022, National Hydrology Dataset (NHD) published in 2023, Protected Areas Database (PAD-US) data published in 2022 and National Land Cover Database (NLCD) data published in 2021. The methodology of the project has largely stayed the same between the WLERA Composite 2016 and WLERA Composite 2024 data release. The notable exception is that there were additional steps used to create the index composite. After the index composite was created using the input parameters and the composite model, a boundary cleaning routine was used to reduce the amount of data noise or lone grid cells present within the index composite. The index composite layer was also reviewed by USGS ecologists after the model was executed and before the data were published, to ensure the accuracy of the results. Based on this review, index composite values returned from the model that did not highlight restorable wetlands were removed from the final dataset. 202406 publication date Complete None planned -83.7447 -82.0833 42.1282 41.2615 ISO 19115 Topic Category environment geoscientificInformation inlandWaters USGS Thesaurus river reaches hydrology wetland ecosystems natural resource management hydrology water quality remediation Marine Realms Information Bank (MRIB) keywords lake lakeshore wetland wetland restoration stream river hydrology resource management water quality Common geographic areas Great Lakes Ohio Michigan Lake Erie Western Lake Erie None.

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), Transportation Investment Generating Economic Recovery (TIGER) dataset U.S. Geological Survey 2016 application/service Geonarrative map website for GLCWRA study https://glcwra.wim.usgs.gov/ Kurt P Kowalski Justin A. Saarinen 2016 dataset https://www.sciencebase.gov U.S. Geological Survey Previous release of data. See "Supplemental Information" for more context. https://doi.org/10.5066/f74t6ghx 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 Western Lake Erie 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.

Using ArcGIS Pro 3.0.3, the "NHDFlowline" feature classes for the NHD 4-digit Hydrologic Unit Codes (HUC) 0410 and 0411 were projected to UTM Zone 17 and then clipped to the WLERA study area. The clipped flowline layers were then merged together and flowline segments which were no longer connected to Lake Erie were deleted. 20230823 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). A new field called 'Value' was added to the interim polygon layer, and each polygon was assigned a value of '1'. Then using the 'Polygon to Raster' tool, the buffered NHD flowline segments were converted into a raster TIFF file (Value Field = Value, Cell assignment type = Cell Center, Priority field = NONE, Cellsize = 10-meter, Snap Raster = WLERA DEM). This interim flowline raster contained cells with values of either '1' or 'NoData' (255). 20230823 Finally, the interim flowline raster created in the previous step was reclassified using the 'Reclassify' tool where all NODATA cells were set to '0' (Mask = WELRA Study Area, Snap Raster = WLERA DEM). By specifying the WLERA Study Area as the mask, we ensure that no raster cells outside of the boundaries of the Study Area would be reclassified but would remain NODATA. The resulting binary raster represents the final raster dataset for Parameter 3 (Flowlines). 20230823 Raster Grid Cell 9327 13625 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 WLERA_P3_Flowlines.tif A raster dataset (in geoTIFF format) representing areas near NHD Flowlines with connection to Lake Erie.
