Clear Water
As we entered yet another lock yesterday (Since entering the
Trent-Severn Canal, we’ve gone through 18 of the 45 locks in the past two days.),
I (Brenda) noticed little shells attached to the lock walls. Were these tiny things “aquatic invasive
species?”
While traveling with Canadians in the Rideau Canal, we
learned from them how dirty (polluted) the Saint Lawrence River once was…that
is (according to the Canadian boaters) until the appearance of zebra mussels (an
aquatic invasive species). They said the
zebra mussels over the course of several years cleaned up the river and, now
that their food source is gone, the zebra mussels are dying and disappearing,
leaving the river water clean and clear.
As much talk (and effort and $$$ expended) has taken place in Minnesota
about how to prevent the spread of aquatic invasive species in our lakes and
river systems, it seems there’s room to learn more about the little
critters (versus aquatic invasive plants) and their life cycles….could there be a “natural” means to rid them of
our waters? Are there potential benefits
to “waiting them out?”
Last night we tied on a wall in Hastings, Ontario. Hastings is a little town with a hardware store
and a couple of restaurants and convenience stores. We’ve traveled 52 of the 241 miles on the
Trent-Severn Canal. We’re reminded of
our Minnesota lake country at every turn.
Ontario offers some of the most beautiful boating grounds we've seen--like Minnesota and Washington! This, too, is "cabin country" or "lake culture." |
Rotary is alive in Cambellford, Ontario! |
This picture turned out blurry, but you get the idea of these tiny mussel shells clinging on the walls of the lock. |
