NOAA Floodplain Model 100k - UC only

This shapefile includes modeled main stem and side channel widths for Columbia basin rivers over 8 meters bank full width. Modeled side channel widths under restoration scenarios and historic conditions are also included. Predicted values are average widths for each 200 m reach. Reach lengths can be used to calculate habitat unit areas. The dataset was built using the 1:100k NHDplus and the Canadian Watershed Atlas stream networks. Reaches falling in lakes and reservoirs have been removed from this layer.
