Cowichan Fence Update

This is the first update for the Cowichan Chinook fence
for 2007.

The fence was installed on 4-6 September with only a few slight struggles to
deal with. One end of the underwater railway rail that the panels are tied
to was bent approximately 2 meters downstream, which had to be straightened
before any panels could be attached. Associated with this was the bulkhead
along the bank that had to be rebuilt. We had to replace one section of the
underwater cable that had worn away, and the brick building where our
equipment was stored had a large hole in one wall where the local
delinquents had bashed their way in. Oh, the telephone line had been cut so
the alarm system was down. Nothing was stolen however.

Just another typical summer of repairs to the Cowichan Fence infrastructure.

As of 18 September, 0800 hrs the count at the fence was 54 adult and 62 jack
chinook and one adult coho. Last year at this time there had been 29 adult
and 18 jack chinook through the fence.

Last year there were extremely low water levels that restricted the upstream
migration of chinook, which would provide some explanation of the low
numbers of chinook last year. Most of the spawners last year were captured
by the hatchery broodstock crew and either kept for brood or transported
upstream to the spawning grounds.

Also, this year the age 3 adults, which is the largest age class for the
Cowichan chinook stock, doesn't have a hatchery component. This was the
reason for low numbers of jacks in 2006.

Finally, if you do not wish to receive these updates, please email me (do
not hit reply all, please) and I will delete you. Also, if there is anyone
you think should receive these updates as well, please let me know and I
will add them to the list. Thanks.

What about the First Nations spearing and snagging chinooks at the end of Boys Rd and in the estuary in September 2006 (I am aware this is their right and I don't dispute this)? The low water last year made for really easy pickings. Are these numbers accounted for in the fence count? Good to hear there are a few more this year :)
