Invasive Rock Snot - Didymo
Stop Rock Snot 
As you may be aware NH waters are now being infected with
a new invasive specie commonly called didymo identified
by NH Fish and Game at:

Didymo is easy to spread by the unaware angler, boater, swimmer
to list but a few recreational groups. Outreach to such people
to inform them of this problem and how to not spread this to
other bodies of waters is of utmost of importance especially
this time of year.
Please review the information available at the link above so that you can recognize Didymo when you see it and avoid spreading it from river to river.
Thank you!
