Well is was about to happen soon enough.

Found this posted on the TCO Fly Fishing web site.

ANGLERS VISITING OUR AREA.........SPECIFICALLLY THOSE OF YOU WHO HAVE JUST FISHED THE DELAWARE RIVER (OR OTHER STREAMS IN NY'S CATSKILL REGION) OR MARYLAND'S GUNPOWDER, PLEASE CLEAN YOUR BOOTS AND WADER WITH A DILUTED BLEACH SOLUTION, OR HOT WATER (OVER 140 DEGREES f) AND LAUNDRY DETERGENT--IT MUST SOAK FOR AT LEAST A HALF HOUR. DIDYMO HAS BEEN IDENTIFIED IN THESE WATERSHEDS. Or even better yet, get a second pair of boots and waders to wear only in infected waters. It's the only sure way not to spread Didymo. .............BE RESPONSIBLE-DONT SPREAD DIDYMO TO THE insert stream name here!!

Just hope people who fish the Delaware River system don't spread it to the rest of the Northeast.
