Interesting *and* scarey. Here's a movie of what it looks like. You
can't help but imagine what it would do to your favorite stream.

Dave,

The latest word I have is that didymo was found above and below the
rte 3 bridge in Clarksville, just south of Pittsburg. Nothing in the
river bewtween the lakes yet, but it would seem to be only a matter of
time. Also, there are so many anglers that fish both the Upper CT and
the Androscoggin, it would seem likely that the Andy is infected too.
I have heard that canoes and kayaks are a bigger threat than fishermen
in spreading didymo, ( I guess because they cover so much more
territory) If this is true, it would be very bad news for the
Androscoggin. You would think that the lodges in the north country
like Lopstick and Tall Timbers would be issuing advisories, but I
haven't heard anything yet.

Further south, I understand there is quite a bit of it present in the
White River, which means the Mascoma, Wells, and Sugar Rivers are also
likely infected. Scary stuff.
