Description: The Waterbody Identifier (WBID) dataset comprises polyline features representing rivers and streams throughout Arizona. This dataset is primarily generated from the National Hydrography Dataset (NHD) medium-resolution (1:100,000 scale) linework, incorporating foundational data from the USGS 1:100,000-scale Digital Line Graph (DLG) hydrography and supplemental information from the EPA Reach File Version 3.0 (RF3). Key Features and Components: The NHD medium-resolution linework is characterized by: • Unique Identifiers: Assignment of distinct identifiers to segments within the surface water drainage system. • Feature Naming: Association of names with various hydrographic features. • Centerline Representation: Provision of centerline representations for areal water bodies, establishing central flow paths within features such as lakes or wide rivers. • Defined Reaches: Segmentation of water bodies (e.g., lakes) into reaches to facilitate the representation of water flow. Applications and Integration: As an integral component of NHDPlus Version 2, under the management and maintenance of the Environmental Protection Agency (EPA), the NHD medium resolution serves as a robust framework for a range of applications, including: • Map production • Flow modeling • Geospatial data maintenance and stewardship This dataset is designed for integration with other spatial data themes, such as administrative boundaries, elevation models, infrastructure, and transportation networks, to facilitate the creation of comprehensive general reference base maps. Positional Accuracy: The positional accuracy of the 1:100,000-scale medium-resolution data indicates that 90% of well-defined features are situated within 167 feet of their true geographic coordinates. Arizona Department of Environmental Quality (ADEQ) Use: The Arizona Department of Environmental Quality (ADEQ) leverages this dataset to accurately define and identify specific segments of rivers and streams. This enables the agency to conduct precise sampling, comprehensive assessment, and effective application of environmental standards to the state's waterways.
