<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Downloaded from USGS NHD 3DEP program website on 4/9/2026 by Sara Dunlap: https://www.sciencebase.gov/catalog/item/69743a66d4be0260181a1222</SPAN></P><P><SPAN>Data last updated on 1/23/2026</SPAN></P><P><SPAN>The USGS 3D Hydrography Program (3DHP) datasets are an integrated, National, 3D-enabled hydrologic dataset derived from the USGS 3D Elevation Program (3DEP) data. For areas where Elevation-derived Hydrography (EDH) has not yet been collected, 3DHP data is supplemented by hydrographic vector data from the (retired) USGS National Hydrography Dataset (NHD). As further EDH-sourced hydrographic data are collected, they will replace the NHD-sourced data in those areas. 3DHP data ingested from EDH sources includes catchments and flowline network derivative attributes. The dataset is open and non-proprietary. Users should be aware that temporal changes may have occurred since this dataset was collected and that some parts of these data may no longer represent actual surface conditions. Users should not use this dataset for critical applications without a full awareness of its limitations. This dataset is not intended to be used for site-specific and/or regulatory determinations. 3DHP datasets include a three-dimensional (3D) hydrography network generated from - and integrated with - elevation data from the 3DEP to better represent stream gradients and channel conditions, along with waterbodies, hydrologic units, hydrologically enhanced elevation and other surfaces, and more consistent and accurate attributes. The product represents the 3DHP dataset and the schema as of September 30, 2025. Future Annual Staged Product releases will reflect the schema at the time the product is generated and include more EDH-sourced hydrologic data holdings.</SPAN></P></DIV></DIV></DIV>
These data create a scalable 3D-in-part geospatial hydrography framework for general purpose use in geospatial analysis, visualization, modeling, cartography and other use cases

Attributes are not systematically verified. Attribute errors may be present.
Topological tests have not been completed, some disconnected features are possible.
Not all hydrologic features on the ground (e.g. stream/river, lake/pond, etc.) may be mapped, and changes may have occurred since originally mapped. The level of mapping detail varies by geographic area. The USGS jointly manages these data with local and regional data stewards, usually at the State level, and some variations in content occur based on differences in local/regional stewardship.
Horizontal accuracy for source data may be available in the original source product metadata file where available.
Vertical accuracy for elevation data may be available in the original source product metadata file where available.
NHD data were used to populate this initial 3DHP dataset.

Elevation-Derived Hydrography (EDH) is a method used by the U.S. Geological Survey (USGS) to create accurate water flow pattern maps and surface water datasets. EDH utilizes lidar and IFSAR data, human-built features, and landscape classifications. EDH was used for populating the hydrologic unit 19050401 in Alaska.

NHD data was used for the 3DHP 'national backbone', that is to get hydrologic coverage across the Nation. It was created in conjunction with the most current WBD, and 3DEP DEMs to create a hydro-enforced DEM for generation of the catchment raster and feature class, and flow direction/accumulation rasters, and used to compute and assign NHDFlowline Value Added Attributes (VAAs) in 3DHP (more details are available in the product's ReadMe file included as part of this dataset.)
