Description:
Abstract:
Gaging stations were extracted from The National Hydrography Dataset (NHD). NHD is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that comprise the nations surface water drainage system. It is based initially on the content of the U.S. Geological Survey 1:100,000-scale Digital Line Graph (DLG) hydrography data, integrated with reach-related information from the U.S. Environmental Protection Agency Reach File Version 3.0 (RF3). More specifically, it contains reach codes for networked features and isolated lakes, flow direction, names, stream level, and centerline representations for areal water bodies. Reaches are also defined to represent 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 set out by the Federal Geographic Data Committee.
Purpose:
The National Hydrography Dataset combines elements of the DLG and RF3: spatial accuracy and comprehensiveness from the DLG and network relationships, names, stream level, and a unique identifier (reach code) for surface water features from RF3. The NHD supersedes DLG and RF3 by incorporating them, not by replacing them. Users of DLG and RF3 will find the National Hydrography Dataset both familiar and greatly expanded and refined. The NHD provides a national framework for assigning reach addresses to water-related entities, such as industrial dischargers, drinking water supplies, fish habitat areas, wild and scenic rivers. Reach addresses establish the locations of these entities relative to one another within the NHD surface water drainage network in a manner similar to street addresses. Once linked to the NHD by their reach addresses, the upstream/downstream relationships of these water-related entities and any associated information about them can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS). GIS can also be used to combine NHD-based network analysis with other data layers, such as soils, land use and population, to help better understand and display their respective effects upon one another. Furthermore, because the NHD provides a nationally consistent framework for addressing and analysis, water-related information linked to reach addresses by one organization (national, state, local) can be shared with other organizations and easily integrated into many different types of applications to the benefit of all. The National Hydrography Dataset is designed to provide comprehensive coverage of hydrologic data for the U.S. While initially based on 1:100,000-scale data, the NHD is designed to incorporate - and encourage the development of - higher-resolution data required by many users. It will facilitate the improved integration of water-related data in support of the application requirements of a growing national user community and will enable shared maintenance and enhancement.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The accuracy of the attributes of the Digital Line Graph data is

estimated to be 98.5 percent. One or more of the following methods were used to test attribute

accuracy: - manual comparison of the source with hardcopy plots. - symbolized display of the

digital line graph on an interactive computer graphic system. - Selected attributes that could not be

visually verified on plots or on screen were interactively queried and verified on screen. In

addition, softwarevalidated feature types and characteristics against a master set of types and

characteristics, checked that combinations of types and characteristics were valid, and that types

and characteristics were valid for the delineation of the feature. Feature types, characteristics, and

other attributes conform to the Standards for National Hydrography Dataset (USGS, 1999) as of the

date they were loaded into the database. All names on reaches were validated against a March

1999 extract from the Geographic Names Information System. The entry and identifier for the names

match those in the Geographic Names Information System. The association of each name to

reaches has not been methodically checked, and so a name may be applied to the wrong reaches.

Anecdotal reviews indicate that 80 percent or more of the named reaches have the correct name.

Reaches were delineated with a batch procedure and were checked extensively during the visual

pass steps of processing. Based on automated quality assurance/quality control checks performed

at various intervals during the processing, approximately 99 percent of the reaches are delineated

according to standards.

Logical_Consistency_Report:
Logical_Consistency_Report: Points, nodes, lines, and areas conform to topological rules. Lines

intersect only at nodes, and all nodes anchor the ends of lines. Lines do not overshoot or

undershoot other lines where they are supposed to meet. There are no duplicate lines. Lines bound

areas and lines identify the areas to the left and right of the lines. Gaps and overlaps among areas

do not exist. All areas close.

Completeness_Report:
The completeness of the data reflects the content of the sources, which, in the initial release of the National Hydrography Dataset, most often are U.S. Geological Survey topographic maps. Features found on the ground may have been eliminated or generalized on the source graphic because of scale and legibility constraints. In general, streams longer than one mile (approximately 1.6 kilometers) were collected. Most streams that flow from a lake were collected regardless of their length. Only definite channels were collected so not all swamp/marsh features have stream/rivers delineated through them. Lake/ponds having an area greater than 6 acres (approximately 2.4 hectares) were collected. Note, however, that these general rules were applied unevenly among maps during compilation. Some map quadrangles have a much sparser pattern of hydrography than do adjoining maps and these differences continue in the digital rendition of these features. A priority for maintenance of the National Hydrography Dataset is the rectification of these differences. Transport reaches are defined on nearly all features of type stream/river, canal/ditch, artificial path, pipeline, and connector. Waterbody reaches are defined on the subset of lake/pond features that were identified as waterbodies during the development of Reach File Version 3. Most attention in applying geographic names was given to transport reaches that follow stream/rivers and waterbody reaches. Near the international boundaries with Canada and Mexico, only the parts of features within the United States are delineated. Detailed capture conditions are provided for every feature type in the Standards for National Hydrography Dataset (USGS, 1999), available online through <http://mapping.usgs.gov/standards/>.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
cal Survey topographic quadrangle maps. These maps

were compiled to meet National Map Accuracy Standards. For horizontal accuracy, this standard is

met if at least 90 percent of points tested are within 0.02 inch (at map scale) of their true position.

Additional offsets to positions may have been introduced where there are many features to improve

the legibility of map symbols. In addition, the digitizing of maps is estimated to contain a horizontal

positional error of less than or equal to 0.003 inch standard error (at map scale) in the two component

directions relative to the source maps. Visual comparison between the map graphic (including digital

scans of the graphic), and plots or digital displays of points, lines, and areas, is used to assess the

positional accuracy of digital data. Linear features of the same type along the adjoining edges of data

sets are aligned if they are within a 0.02 inch tolerance (at map scale). To align the features, the

midpoint between the end of the corresponding features is computed, and the ends of features are

moved to this point. Features outside the tolerance are not moved; instead, a feature of type

connector was added to join the features.

Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Statements of vertical positional accuracy for elevation of water surfaces are based on accuracy statements made for U.S. Geological Survey topographic quadrangle maps. These maps were compiled to meet National Map Accuracy Standards. For vertical accuracy, this standard is met if at least 90 percent of well-defined points tested are within one-half contour interval of the correct value. Elevations of water surface printed on the published map meet this standard; the contour intervals of the maps vary. These elevations were transcribed into the digital data; the accuracy of this transcription was checked by visual comparison between the data and the map.

Overview_Description:
Entity_and_Attribute_Overview:
The National Hydrography Dataset is a comprehensive set of digital spatial data that encodes information about naturally occurring and constructed bodies of water, paths through which water flows, and related entities. The information encoded about features includes classification by type, other characteristics, a unique common identifier, the feature length or area, and (rarely) the elevation of the surface of water pools and a description of the stage of the elevation. For reaches, encoded information includes a reach code, the date the reach code was assigned, a unique common identifier, the reach length or area, and, for transport reaches, the stream level. Geographic names, and their identifiers in the Geographic Names Information System, are assigned to reaches or, if no reach is available, to features. The data also contain relations among reaches that encode the direction of water flow, metadata, and information that supports the exchange of future updates and improvements to the data.
