NHD INDEXED LOCATIONS FOR FISH CONSUMPTION ADVISORIES
Description:
Fish consumption advisories and fish tissue sampling stations are reported to EPA by the states. Sampling stations are the locations where a state has collected fish tissue data for use in advisory determinations. Fish consumption advisory locations are coded onto route.drain (Transport and Coastline Reach) feature of NHD to create Point Events and Linear Events. Fish consumption advisory locations are coded onto region.rch (Waterbody Reach) feature of NHD to create NHD Waterbody Shapefiles. In addition to NHD reach indexed data there may also be custom shapefiles (point, line, or polygon) that are not associated with NHD and are in an EPA standard format that is compatible with EPA's Reach Address Database. These custom shapefiles are used to represent Fish consumption advisory locations that are not represented well in NHD.
