On several sites there are threads about Didymo and how bad the stuff is. It seems Didymo likes cold, clear streams with faster flows - kinda like trout 
Well one of the regulars here at the shop just came back from the White River and he was told Didymo is in the White and that he should dry and or bleach his gear before wading in any other waters.
Here's a fact sheet you can read with more info.

Deadly Algae, Didymo, Found In Vermont Waters
The world is shrinking! We are a society of outdoor recreation and as humans we love water. Today, when we can easily toss a canoe or a kayak on top of the car and move about to more and more rivers with more and more launch sites, we see increased numbers of people using the waters. Fishing is easier with greater access and with the ability to fish the waters of Vermont today and wet a line in New Zealand tomorrow, it is safe to say that the world is getting very tiny.

I am sick at heart to hear of didymo in the White. While I have been a fly fisher for almost all of my life, I really cut my teeth living on that river from 1988 to 1992. It was and hopefully will remain a beautiful river with beautiful fish which taught me much of what I know about our passion. |

Nasty stuff for sure. I wonder how much of it is transplanted by animals vs. fishermen? We can all do the right things by using the right type of wading boots, cleaning and drying them, etc. but how do you control the beasties? From the sounds of it, it doesn't take much to transplant this stuff  |

Ya know...I have read alot of stuff about this and all the "lets ban felts" and such...but honestly...IMHO
The best way to help stem the spread, is for folks not to go to these infested waters in the first palce, and if they must because they are the home water or somethng or other please, don't go somewhere else with your frigged up gear...cripes stay home!
Since I heard the Matapedia had this stuff last year and i was planning on fishing it too...I cancelled...it was too risky...
IMHO everyone in Maine should stay out of the Connecticut and the White and the Matapedia...WTF? Don't we have plenty of our own waters to fish? why even risk it? why go through the hassle of washing your gear on an unneccessary trip to an infested water? I mean you can if you want...but really? is it all that necessary?
cripes ...going up there now is like playing russian roulette...just stay home...
I have heard the suggestion of closing these waters to recreation...and it went over like a lead balloon with the locals and the local government officials...and to a certain extent I can understand why they would think that way...but if they want to stay in there own infected water with thier own infected boats and infected waders and infected reels and infecetd other stuff...that's ok just as long as they stay there...
WE can "voluntarily" keep away...voluntary quarntine....I think as responsible anglers ...we should...the locals keep thier recreational use.....once ingfected it it can't harm them to keep using it (provided they stay put!) But with voluntary quarantine in effect the water is closed to all other's recreation...at least the responsible parties who have enough sense to sdtay the **** away!....
Guides who work the infested water? I feel for them...but ...they should move on to other water....shit happens.. all guides run similar risks...we're all in the same boat...i used to guide atlantic salmon on the Penobscot...but I can;'t anymore...like i said...shit happens...

First Northeast Infestation of “Didymo” Discovered In Vermont
Invasive could threaten Maine’s Pristine Rivers and Streams. Maine to combat potential infestation with strategy of Check, Clean and Dry.
AUGUSTA, Maine – With the discovery of the aquatic nuisance algae known commonly as “didymo” or “rock snot” on the Vermont/New Hampshire Border in the Connecticut River, the Maine Department of Inland Fisheries and Wildlife and the Maine Department of Environmental Protection are alerting boaters, anglers, kayakers, canoeists and others to take action to prevent this new invasive threat to Maine’s waters.
The confirmed discovery in Bloomfield, Vermont is the first official report of Didymosphenia geminata in the Northeastern United States.
Didymo can form extensive ‘blooms’ on the bottoms of rocky river beds, essentially smothering aquatic life forms such as macroinvertebrates (aquatic insects), native algae, and other organisms. Additionally, the physical appearance of the bloom is aesthetically unpleasing, and can reduce the recreational values of a waterbody. Didymo uses stalks to attach to rocks and plants in a river system. The diatom creates these stalks, which can form masses 10-12 inches thick on the river bottom, and trail for lengths of 2-3 feet in the current.
“Didymo can be spread by transporting a single cell, it forms dense mats, which can kill aquatic insect life, essentially starving out fish populations in the area,” said John Boland, Director of Fisheries for IFW. “The ease with which it can be spread is a real concern for anyone who enjoys Maine’s waters. All of Maine’s rivers and streams are at risk.”
Both IFW and DEP are urging anglers and other water recreationists to use these procedures for preventing the introduction and spread of didymo: Check, Clean and Dry.
Check: Before leaving a river or stream, remove all obvious clumps of algae and look for hidden clumps. Leave them at the affected site. If you find any later, do not wash them down drains; dispose all material in the trash.
Clean: Soak and scrub all items for at least one minute in hot (140 degrees F) water, a two percent solution of household bleach or a five percent solution of salt, antiseptic hand cleaner or dishwashing detergent.
Dry: If cleaning is not practical, after the item is completely dry to touch, wait an additional 48 hours before contact or use in any other waterway.
“These steps are more than suggestions,” said IFW’s John Boland. “They’re absolutely essential for preserving the quality of Maine rivers and streams.”
There are currently no known methods for controlling or eradicating didymo once it infests a water body. “Preventing the spread of Didymo is our best defense,” said Tom Danielson, a biologist with the Maine Department of Environmental Protection. “We have tested algae at over two hundred locations on Maine rivers and streams, and it has not yet been detected in Maine’s waters.”
Didymo is generally found in colder, low nutrient, high clarity streams. However, recently there have been discoveries of Didymo in rivers and streams in warmer climates, as well as streams with more nutrients, streams with moderate clarities and even some tannic (tea colored) waters. Didymo is currently found in Europe (Scotland, Poland) and it is spreading throughout the northwestern region of the US. It is also in Quebec, British Columbia and New Zealand.
In the past several years, didymo has expanded its range in the Western United States and has infested rivers and streams in several southeastern states, including Virginia, West Virginia, Tennessee and North Carolina.
In 2004, didymo was discovered in New Zealand. Within 18 months it had spread to 12 rivers on the South Island, forming nuisance blooms at several locations. New Zealand officials have instituted severe penalties for intentional spread of the algae, and are intensively researching control and prevention methods.
If you feel that you have discovered didymo, please contact the Maine Department of Environmental Protection at 1-800-452-1942 or email milfoil@maine.gov.
