Tagging of wood and layout of the survey grid began in the summer of 1982. This process was quite time consuming, so the annual surveys did not begin until 1985. Tagging and grid layout were completed in 1986.
In 1994, a road culvert between the clearcut and old-growth reaches was removed, along with much of the road fill used to support it. The culvert was replaced by a bridge. The gaging station is located less than 20 meters below the downstream end of the culvert, and was also redesigned to handle potentially higher discharges. The SITECODE "CT" refers to this culvert reach.
