Description: The department, federal agencies, and nongovernment organizations operate counting projects to count the numbers of migrating fish (primarily salmon), using weirs, sonars and counting towers in a number of streams throughout Alaska. This tool is used by the various fisheries divisions for a variety of management objectives. This website has compiled counts from a number of different sources to provide inseason and historical data.This site does not include all of the sites in the state, only those for which inseason data is readily accessible. All counts for the current year are considered preliminary data and subject to change.
