Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This shapefile represents the rivers thalweg. The thalweg was automatically generated and manually adjusted as needed. Data was processed in reference to NAD83 (CORS96), however the horizontal datum for this dataset is defined as NAD83 (HARN) as the difference is generally small and allows for greater ease of use with data in different datums. The vertical datum is NAVD88, Geoid 12B, and it is projected in Washington State Plane North. Units are in US Survey Feet. Quantum Spatial collected the Tacoma Water Service Area, Green River Topobathymetric LiDAR data for Washington State Department of Natural Resources between 05/27/18 and 05/28/18.</SPAN></P></DIV></DIV></DIV>
