Stream Keepers
The past month we
have been active clearing the logging road of overhanging branches on the way
to our smolts box and Swan Lake. The water temperature has been around 7c with
no fish moving downstream until last Tuesday the 8th when the temperature
came up to 10c. We had 3 Wild Coho around 85 to 95 mm on the Tuesday then by
the following Saturday the temperature rose to 12c but only one fish in the
box.
No fish at that
temperature could only mean one thing, we had a hole somewhere on the fence and
the fish were getting through bypassing our two pipes. Sure enough the wire
mesh separated at the bottom of one panel with the water pushing open a large
hole. We placed a piece of plywood over the hole until we could return on the
following Tuesday. We repaired the hole then counted the fish in the box, 45
wild Coho and one water beetle. The size of the smolts at 85 to 95 is a result
of the cold spring last year, the fry were late in emerging and did not get
enough thermal units to grow larger over the past year.. Among the 72 we had
last week the 18th of May we had some around 112 to 125mm, these
would be 2 year olds that remained in the lake a extra year and will go to the
ocean for two more years before returning as 5 to 6 pound adults, a amazing journey
while putting on all that weight in just two short years. We expect the numbers
to be steady until the end of June when they all will be heading out to the
Salish Sea. Last month we had a meeting with Environment Canada, Ducks
Unlimited and DFO regarding the estuary at the head of the bay. We met at the
hall in Nanoose in the morning then went for a walk in the estuary then up
Bonnel creek in the afternoon to view the small woody debris log jam, which
formed over the past year. DU had concerns about the stream jumping the bank
and eroding a new channel into their pond. Their was talk of bringing in a
machine to clear it out which I was not too happy with as the machine would
have had to take out some live trees on the bank to access the site. The other
alternative was to walk the machine up the creek, which also would have
resulted in tree removal and damage to the existing habitat. Thankfully the
lady from DFO concurred with me and the decision was made to leave it alone and
allow nature to take it course. On the left bank there is a small channel,
which allows for fish access both up and down stream around the logjam. Over
the summer months we will be salvaging stranded fry from drying pools This is a
great time for the kids to see real Wild Salmon in their natural habitat and do
some thing to preserve our wild Salmon for the future.
