Service Description: To be used to identify the spatial extent of the fish consumption advisories and fish tissue sampling stations locations. These waters can be linked to the fish consumption advisories and fish tissue sampling stations locations stored in the EPA National Listing of Fish and Wildlife Advisories (NLFWA) database for query and display. The Source_FeatureID field in the event table/shapefile can be linked to the ADVNUM in EPA's NLFWA database.

Description: The Fish Consumption Advisories dataset contains information on Fish Advisory events that have been indexed to the EPA Office of Water NHDPlus v2.1 hydrology and stored in the Reach Addressing Database (RAD). NHDPlus is a database that interconnects and uniquely identifies the millions of stream segments or reaches that comprise the Nations' surface water drainage system. NHDPlus provides a national framework for assigning reach addresses to water quality related entities, such as fish advisories locations. 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. The assignment of reach addresses is accomplished through a process known as reach indexing. 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 NHDPlus flowline features to create point and linear events. Fish consumption advisory locations are also coded onto NHDPlus waterbody features to create area events. In addition to NHDPlus-reach indexed data, there may also be custom events (point, line, or area) that are not associated with NHDPlus. Although these Fish consumption advisories are not represented in NHDPlus, the data created for them are in an EPA standard format that is compatible with EPA's Reach Address Database.
