BLM OR Fish Anadromous Arc Hub

FISH_ANADROMOUS_ARC: This feature class is used to determine whether a particular anadromous fish species is present in a stream, which can affect protection buffer widths in land management plans and activities. The data comes primarily from the National Hydro Dataset (NHD), and is from actual observations or from modeled fish presence. While each district carried out their determinations in various ways, generally verification means that the fish biologist or other trained specialist was able to see the fish at the stream. This data is a descendent of the Aquatic Resources Information Management System (ARIMS).
