Description: This is a Washington State extract downloaded from the USGS in March 2019 and projected into WA State Plane Coordinates North. Strahler Stream Order has been added. NHDFlowline is the fundamental flow network consisting predominantly of stream/river and artificial path vector features. It represents the spatial geometry, carries the attributes, and contains linear referencing measures for locating features or “events” on the network. Additional NHDFlowline features are canal/ditch, pipeline, connector, underground conduit, and coastline.
The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. This high-resolution NHD, generally is developed at 1:24,000/1:12,000 scale, but many areas of Washington State have been improved to 1:4800 scale. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee. Stream Orders in Washington State range from 1 to 10. The smallest headwater streams are a 1, and the Columbia River is a 10.This feature class contains a BETA version of Water Type attached to the Skagit and Samish River Basin NHDFlowlines. This Beta version of the Water Type is the result of a pilot project. The field is for users of NHD who want access to Water Type and who are not under Forest Practices rules. The Water Type uses Shorelines Master Program type S streams and Fish Presence Data from both WA Dept Natural Resources and WA Dept Fish and Wildlife.
Description: Fema Flood Dataset for Whatcom County, WA including the 100 Yr Floodplain & Floodway. The Fema 100 Yr Floodplain are areas that will be inundated by a flood event having a 1-percent chance of being equaled or exceeded in any given year, as derived from FEMA Flood Insurance Rate Maps. A "Regulatory Floodway" means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height. Communities must regulate development in these floodways to ensure that there are no increases in upstream flood elevations.

Description: Watershed boundaries for Water Resource Inventory Area 1 were delineated for the 2514 Watershed Planning Project and are a composite of computer generated and human interpreted surface water Delineations. They are based on the USGS Watershed Boundaries Map (January 2000). They are a composite of the following agencies’ data: USGS, Whatcom County PDS, Whatcom County Conservation District, City of Bellingham, City of Everson, Lummi Natural Resources, US Forest Service, and British Columbia MELP. Drainage boundaries were verified with WA-DNR and WDFW SSHIAP 1:24,000 scale hydrography, USGS 7.5 minute quadrangle maps, 1991/1998 orthophotos, and field collected information.

Description: This is a Washington State extract downloaded from the USGS in March 2019 and projected into WA State Plane Coordinates North. Waterbodies such as lake/pond features are represented in NHDWaterbody. They portray the spatial geometry and the attributes of the feature. These water polygons may have NHDFlowline artificial paths drawn through them to allow the representation of water flow direction. Other NHDWaterbody features are swamp/marsh, reservoir, playa, estuary, and ice mass.

Description: This is a Washington State extract downloaded from the USGS in March 2019 and projected into WA State Plane Coordinates North. Strahler Stream Order has been added. NHDArea contains many additional water-polygon features. One of the more important is the stream/river feature. It represents the areal extent of the water in a wide stream/river with a basic set of attributes. These polygons typically encompass NHDFlowline artificial paths that represent the stream network. Artificial path carries the critical attributes of the stream/river, whereas NHDArea represents the geometric extent.

Description: Watershed based boundaries for Water Resource Inventory Area 1 were delineated for the 2514 Watershed Planning Project and are a composite of computer generated and human interpreted surface water Delineations. Drainage was included for Padden to reflect regulatory overlay district that was created for the area outside the City of Bellingham municipal boundary. A Samish drainage boundary was also included for regulatory purposes. Boundaries are predominantly based on the USGS Watershed Boundaries Map (January 2000). They are a composite of the following agencies’ data: USGS, Whatcom County PDS, Whatcom County Conservation District, City of Bellingham, City of Everson, Lummi Natural Resources, US Forest Service, and British Columbia MELP. Drainage boundaries were verified with WA-DNR and WDFW SSHIAP 1:24,000 scale hydrography, USGS 7.5 minute quadrangle maps, 1991/1998 orthophotos, and field collected information.

Description: Water Resource Inventory Areas (WRIA) for Washington State at 1:24,000 scale. WRIAs were formalized under WAC 173-500-040 and authorized under the Water Resources Act of 1971, RCW 90.54. Ecology was given the responsibility for the development and management of these administrative and planning boundaries. These boundaries represent the administrative under pinning of this agency's business activities. The original WRIA boundary agreements and judgments were reached jointly by Washington's natural resource agencies (Ecology, Natural Resources, Fish and Wildlife) in 1970. This dataset has been selected for just the WRIA 1 Boundary and reprojected to WA State Plane North NAD 83 for use within Whatcom County, WA.
