Service Description: The Water Mask is a grid file indicating all surface waters; including, lakes, rivers, streams, wetlands, estuaries, and nearshore ocean waters, as mapped in the 1:100,000-scale. The Water Mask is created using grid analysis to combine the surface water features of two datasets. First, the surface water features from the 2016 National Land Cover Database (NLCD). Features included are 'Open Water' (code 11), 'Woody Wetlands' (code 90) and 'Emergent Herbaceous Wetlands' (code 95). Source data used was NLCD2016 version 1 (see NLCD metadata for more information). Second, the flowline and waterbody features as represented in the catseed grid from the National Hydrography Dataset (NHD) Plus version 2. Source data used was NHD Plus Version 2.1 (see NHD Plus Version 2.1 metadata for more information). A cell value of 1 in the grid indicates that the cell represents surface water. The combination of these two datasets into a grid represents surface water and is referred to as the Water Mask.
