Just read Craig Mathews blog on the Blue Ribbon site http://blue-ribbon-flies.com/blog (post dated 16 Jan, 2011) and he mentioned the whitefish pop had crashed on the Madison. Can't remember the last time I caught one below Quake, although I stick with dries most of the time. Since whities are a pretty good indicator for water quality, this could be of some concern.

Regards,
Scott
