The Elwha dam removals consisted one of the largest dams removed in history due to economical and ecological reasons. This resource contains a river mask prior to the removal in 2011 and three subsequent mask files from 2013, 2015, and 2017 showing the morphological evolution of the channel. The raster data were created using publicly available NAIP imagery. First, supervised classification was performed to classify all water, non-water, water shadow, and non-water shadow pixels. The clear water and shadow water pixels were then reclassified as one, and finally, raster painting was performed on bridge cross sections etc to make sure that the mask accurately shows water pixels for each time period.
