Lakes/Reservoirs

Water Bodies such as lake and reservoir features are represented in this layer pulled from the National Hydrography Dataset (NHD). These data were used to erase areas of lakes and ponds from every raster metric in the project dataset. This dataset is a subset of vector polygon NHD water bodies, encompassing the project boundary and converted to a raster grid at 30m resolution.
