Washington Hydrography Framework

PROJECT SCOPE

The project scope is defined by several areas of interest. These are: functional capabilities, data products, geographical area, and participant organizations. A brief summary of the project is noted below.

Functional Capabilities - A hydrography database will be established for which the users will have access and update capabilities.

Data Products - The project involves surface waters only. Represented within a routed dynamic segmentation model, it supports: water bodies represented by lakes, ponds, reservoirs, wetlands, bays/ocean, and the shorelines bounding those features; water courses represented by streams, rivers, aqueducts, conveyances, direction of flow, stream routes, stream segments, and river banks; and water feature points represented by springs and seeps. This database will also contain structure for the linear, polygonal and point data needed to support flood inundation information. All spatial information will be organized in a logical hydrography structure based on some delineation of hydrologic watersheds, and will be networked in the appropriate fashion. Two data items within the database will be developed and maintained to facilitate cross-walks to other established hydrography data sets. This project will include a complete set of project and metadata documentation.

Geographical area - The Project will be applicable to the entire state of Washington.

Participant Organizations - The project will focus on the identification of needs of the members or partner organizations and will identify a caretaker organization(s). Partners will establish and agree to a core set of standard features and attributes; and ensure continuing collaborated maintenance of the data set in order to keep it current.
