Status of the Fishery (as of 09/13/2006)

Brook trout were abundant in Gadwall Lake in the fall of 2006, and they were exceptionally large. However, most of the fish taken were four years old, and few will survive beyond the winter of 2006-2007. Numbers of younger fish available to replace them did not appear to have been high. Anglers fishing Gadwall lake in 2007 and 2008 are likely to see fewer, and smaller, fish than results of the 2006 assessment would indicate.
