Table A-6. NHDWaterbody Class <br />Attribute Description Type <br /> A numeric code that uniquely identifies a reach. This 14- <br /> digit code has 2 parts: the first 8 digits are the hydrologic <br /> unit code for the subbasin in which the reach is located; <br /> the last 6 digits are a sequentially ordered, arbitrarily <br />ReachCode assigned number. Provides a handle for linking additional esriFieldTypeString <br /> descriptive information to a water body. Theoretically, a <br /> single water body reach may be composed of one or more <br /> polygons. However, in practice, each water body is <br /> assigned a separate reach code (based on discussions with <br /> USGS ersonnel). <br /> Unique identifier associated with descriptive feature type. <br /> Feature types included in this table are: Area of Complex <br />FType Channels, CanaUDitch (2-dimensional), Estuary, Ice Mass, esriFieldTypeInteger <br /> Lake/Pond, Reservoir, Sea/Ocean, Swamp/Marsh, <br /> Streaill/River (2-dimensional), Playa, and Wash. <br /> Unique five-digit code associated with teat description <br />FCode that contains all feature characteristics and values (e.g., esriFieldTypeInteger <br /> "Reservoir: Reservoir T e = A uaculture".) <br />Page 17 of 17 ~IZlverslde Technnlo~yv Inc. <br />4s':rkv Resuurce.s Ergmee: mg end ~C9 nsuNrng <br />
