Alaska Department of Fish and Game, Fishery Data Series No. 12-79, Anchorage
Snorkel surveys have been conducted annually since 1997 to monitor the spawning abundance of steelhead Oncorhynchus mykiss in 10 index streams in Southeast Alaska, and were conducted again during 2010 and 2011. These index streams were surveyed by a two- or three-person team using snorkel gear between mid-April and early June. Snorkel surveyors observed peak counts (counts bracketed by lower counts) in nine of the index streams during 2010 and six during 2011. The peak survey counts in index streams during 2010 and 2011 were generally lower, as observers reported average to below average peak counts in most index streams. No “record high” peak counts were recorded in either 2010 or 2011.
