The National Waterway Network is a comprehensive network database of the nation's navigable waterways. The original data set covers the 48 contiguous states plus the District of Columbia, Hawaii, Alaska, Puerto Rico and water links between. The nominal scale of the dataset varies with the source material. The majority of the information is at 1:100,000 with larger scales used in harbor/bay/port areas and smaller scales used in open waters.This data layer was edited to provide waterways within or adjacent to the state of Washington. It was downloaded from http://www.data.gov/, January 2015. |
