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.

Aerial retardant avoidance area for hydrographic feature data are based on high resolution National Hydrographic Dataset (NHD) produced by USGS and available from the USFS. Forests and/or regions have had the opportunity to modify the default NHD water representation (300ft buffer from all water features) for their areas of interest to accurately represent aerial fire retardant avoidance areas as described in the 2011 Record of Decision for the Nationwide Aerial Application of Fire Retardant on National Forest System Land EIS. These changes have been integrated into this dataset depicting aerial fire retardant avoidance areas for hydrographic features. The following process was used to develop the hydrographic areas to be avoided by aerial fire retardant. Initially, all intermittent/ephemeral and perennial features were buffered by 300 feet by the Forest/Region units. Subsequently, Forest/Region units may have extended these buffers locally based on their requirements. There may be overlapping features that have been created during the buffering process, so one must dissolve features before calculating any area values. Data is symbolized by FCODE. Using the FCODE attribute, streams/rivers/waterbodies are categorized into perennial and intermittent/ephemeral types. Avoidance features (streams and rivers) with FCODES 46003 and 46007, as well as features (lakes and other waterbody) with FCODES 39001, 39005, 39006, 43614, 46601 are considered intermittent/ephemeral features. All other FCODES are considered to be perennial features. All underground and covered water features (e.g., pipelines) are excluded. When symbolizing this information, perennial features should be drawn on top of intermittent/ephemeral features to give the proper message. Data displays at scales larger than 1:1,250,000. Data uses a Web Mercator projection.

Classified Flowlines, 20190426 (1:2,400) - Shows classified drainage flowlines as streams, rivers, canals, ditches, artificial paths, connectors and pipelines for all watersheds in Indiana.This layer is derived from the local-resolution National Hydrography Dataset (NHD), and provides currently available data as of April 26, 2019. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. Also, high-resolution NHD, generally developed at 1:24,000 to 1:12,000 scale, adds detail to the original 1:100,000-scale NHD. The local resolution NHD is developed at 1:2,400 scale, and adds even more detail to the NHD. This dataset is complete and includes data for all of the following thirty-eight HUC08 subbasins in Indiana: Auglaize (0410007), Blue-Sinking (05140104), Chicago (07120003), Driftwood (05120204), Eel (05120104), Eel (05120203), Flatrock-Haw (05120205), Highland-Pigeon (05140202), Iroquois (07120002), Kankakee (07120001) Little Calumet-Galien (04040001), Lower East Fork White (05120208), Lower Great Miami (05080002), Lower Ohio-Little Pigeon (05140201), Lower Wabash (05120113), Lower White (05120202), Middle Wabash-Busseron (05120111), Middle Wabash-Deer (05120105), Middle Wabash-Little Vermilion (05120108), Middle Ohio-Laughery (05090203), Mississinewa (05120103), Muscatatuck (05120207), Patoka (05120209), Salamonie (05120102), Silver-Little Kentucky (05140101), St. Joseph (04050001), St. Joseph-Maumee (04100003), St. Mary’s (04100004), Sugar (05120110), Tippecanoe (05120106), Upper East Fork White (05120206), Upper Great Miami (05080001), Upper Maumee (04100005), Upper Wabash (05120101), Upper White (05120201), Vermilion (05120109), Whitewater (05080003), Wildcat (05120107).The following is excerpted from metadata provided by the IDNR: "In order to meet the USGS NHD data model for flowlines, all new flowlines resulting from the Indiana NHD local resolution upgrade project that could not be categorized (artificial path, canal/ditch, coastline, connector, pipeline, stream/river perennial, stream/river intermittent, or underground conduit) were given an FTYPE of Stream/River and an FCODE of Stream/River (46000). Water may or may not be present outside of rain events and may or may not exhibit channelization typically associated with streams. Those features are considered to be 'Unclassified Flowlines'. Records from the reprojected NHDFlowline feature class where FCODE = 46000 were extracted out of this dataset. All records from the source NHDFlowlines where FCODE 46000 can be found in this 'Classified Flowline' dataset."

This layer was developed by the Natural Resources Department of the Atlanta Regional Commission. The dataset contains polygonal hydrographic features including lakes, ponds, reservoirs, swamps, and marshes in the Metropolitan North Georgia Water Planning District.Original data were captured from the NHDWaterbody geospatial data layer included in the High Resolution National Hydrography Dataset Plus (NHDPlus HR). Features in the NHDWaterbody geospatial layer that intersected the Georgia State boundary were selected and spatially joined to Georgia county boundaries and the WBDHU8 geospatial data layer found in the U.S. Geological Survey's Watershed Boundary Dataset. Layers were spatially joined using the Largest Overlap matching method. The spatial join was removed upon calculating values for the COUNTY_FIPS, COUNTY_NAME, HUC8_ID, and HUC8_SUBBASIN attributes. The CLASS attribute was created to identify Lakes equal to or larger than 10 acres as Major and less than 0.5 acres as Minor. Data in the HYDRO_CAT and RESERVOIR_TYPE attributes were sourced from values encoded in the Feature Code (FCode) field of the NHDWaterbody geospatial data layer.Attributes:FEATURE = Type of hydrologic featureCLASS = Class used to identify major and minor waterbodiesGNIS_ID = A permanent, unique number assigned by the Geographic Names Information System (GNIS) to a geographic feature name for the sole purpose of uniquely identifying that name application as a record in any information system database, dataset, file, or documentGNIS_NAME = The Geographic Names Information System (GNIS) assigned proper name, specific term, or expression by which a particular geographic entity is known.HUC8_ID = 8-digit hydrologic unit code used to identify subbasins in the hydrologic unit systemHUC8_SUBBASIN = Subbasin name of the 8-digit hydrologic unit code in the hydrologic unit systemCOUNTY_FIPS = County Federal Information Processing System (FIPS) codeCOUNTY_NAME = County nameHYDRO_CAT = Hydrographic feature categoryRESERVOIR_TYPE = Type of reservoirACRES = Area of the feature in acresELEVATION = The vertical distance from a given datumGlobalID = A type of UUID (Universal Unique Identifier) in which values are automatically assigned by the geodatabase when a row is createdlast_edited_user = User to last edit featurelast_edited_date = Date feature was last editedShape = Feature geometryShape_Length = Length of the feature, which may differ from the field measured length due to differences in calculation.
