The hydroperiod dataset was derived from the Lake Ontario Digital Elevation Model (DEM) and Lake Ontario water level records collected at the NOAA station in Oswego, New York and represents the percentage of time the landscape is flooded. The hydroperiod data was used to identify areas which are more likely to be flooded as these areas are better suited to support a wetland habitat. This dataset was created with methodology outlined at https://glcwra.wim.usgs.gov/. |

This dataset is part of the U.S. Geological Survey (USGS) Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) initiative. This dataset represents the percentage of time the landscape is flooded for the Lake Ontario Restoration Assessment (LORA) study area.The GLCWRA initiative identifies coastal wetland areas that have the greatest habitat restoration potential. The data model uses seven parameters to identify and rank wetland restoration areas, resulting in a composite index raster that can be used by ecological managers and planners to assist with the selection of wetland restoration sites. The parameters are Parameter 0: Mask, Parameter 1: Hydroperiod, Parameter 2: Wetland Soils, Parameter 3: Flowlines, Parameter 4: Conservation and Recreation Lands, Parameter 5: Impervious Surfaces, and Parameter 6: Land Use (represents developed areas without impervious surfaces but high societal value). The ancillary data include dikes, degree flowlines, study area and culverts. These data layers are put through an ecological model, which results in a composite restoration index of ranked restoration areas. |
