Service Description: The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, 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, much like addresses on streets. 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 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.

Description: This dataset has be derived from the National Hydrologic Dataset (NHD). The derivation and modification process has been performed by AGRC to provide a general puposes feature class of water bodies for cartographic purposes. Four fields have been added to this feature class (FType_Text, FCode_Text, InUtah, IsMajor, and Submerged) and features have been split at the state boundary.
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. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) 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.
Data released to the Receiving Agency (RA) remains the property of the originating data source (see Source_Information) and cannot be reproduced for sale by the RA without the written consent of that data source. Redistribution of datasets unchanged as obtained from the AGRC and without fee is allowed. Any hardcopies utilizing these data sets shall clearly indicate their source. If the RA has modified the data in any way, they are obligated to describe the types of modifications they have performed on the hardcopy map. RA specifically agrees not to misrepresent these data sets, nor to imply that changes they made were approved by the AGRC.The Utah Automated Geographic Reference Center (AGRC) has adopted the following spatial data disclaimer to be explicitly included or referenced in all geospatial data, mapping products, and services created or hosted at AGRC including the contents of State Geographic Information Database (SGID). This product is for informational purposes and may not have been prepared for, or be suitable for legal, engineering, or surveying purposes. Users of this information should review or consult the primary data and information sources to ascertain the usability of the information. AGRC provides these data in good faith and shall in no event be liable for any incorrect results, any lost profits and special, indirect or consequential damages to any party, arising out of or in connection with the use or the inability to use the data hereon or the services provided. AGRC provides these data and services as a convenience to the public. Further more, AGRC reserves the right to change or revise published data and/or these services at any time.Furthermore, it is the official policy of the AGRC:
· that the adopted disclaimer be used on all hard copy maps produced from geospatial data, and that the date and source of the data be included on the map;
· that spatial data producers be allowed to extend the adopted disclaimer with additional language further defining the limits of their liability;
· that a more robust disclaimer may be used in conjunction with any and all geospatial data published on the Internet, on a separate page preceding access to the data, with an accept/reject option for users;
· that standardized metadata be included with any distribution of all geospatial data; and
· that the disclaimer above may be used as a blanket disclaimer for documents containing a number of small maps.
