Baker River (Washington) only known sustaining population of Sockeye salmon in the Skagit River drainage basin. The Washington Department of Fish and Wildlife (WDFW) has determined the Baker River sockeye to be genetically distinct from other sockeye salmon. As of 1992 the condition of the population was listed as "critical". In 1985 only 92 adults were found to return to the river. Since the 1990s, however, the population has recovered somewhat, in part due to improvements in the smolt trapping and transportation system. 20,235 fish were counted in 2003 and since 2010, the numbers have been between 10,000 & 30,000 fish counted per
Fish species of Aravaipa Canyon itself. Various methods are used to survey the type and abundance of fish species present at each location. The most common of these is seining, a method that involves dragging a long net through the water and catching many fish at a time. This is best done by two individuals (one on either side of the net) who run downstream, scooping up the fish that are attempting to swim upstream against the current. Another form of seining involves the same two people on either side of the net, but this time they plant the edges of the net into the
