Alaska Anadromous Fish Streams

This dataset represents streams from the Alaska Department of Fish and Game "Catalog of Waters Important for Spawning, Rearing, or Migration of Anadromous Fishes." This dataset represents the combination of several regional datasets produced by the Alaska Department of Fish and Game. This dataset is intended to be used with the Alaska Anadromous Fish Points dataset. The individual shapefiles from which this dataset was compiled were produced for general visual reference and to aid users in generating various natural resource analyses and products. The shapefiles depict the known anadromous fish bearing lakes and streams within Alaska (from the mouth to the known upper extent of species usage). It incorporates data from a variety of sources including: USGS Digital Line Graph (DLG) and National Hydrography Dataset (NHD) hydrography data; Alaska Department of Natural Resources hydrography layer; and Alaska Department of Fish and Game shapefiles for the "Atlas" and "Catalog". Alaska Department of Fish and Game updates the Anadromous Streams data regularly. Note that stream numbers, locations, extent of cataloged habitat or species utilization of a given stream may change from year to year. Data for the shapefiles are current as of the 2007 revision of the "Atlas to the Catalog of Waters Important for the Spawning, Rearing or Migration of Anadromous Fishes" and the "Catalog of Waters Important for the Spawning, Rearing or Migration of Anadromous Fishes" effective June 1, 2007.
