Birch Creek 3DHP

The USGS has updated the 3D Hydrography Program (3DHP) web service. This updated service includes the first new hydrography data published by the 3DHP and aligned with 3D Elevation Program (3DEP) data.  The updated data, in the Okanogan River area of Washington State and the Birch Creek watershed in Alaska, are integrated with older data migrated from the retired National Hydrography Dataset.  As additional 3DHP data are processed the NHD-based data will be replaced.
