Last week I looked at chinook and their
relationship with structure. Here are a few more thoughts.
There are times when chinook are not
related to structure. I mentioned open ocean fish far above the bottom, nursing,
but there are circumstances closer to home. In Saanich Inlet, for instance, chinook
mosey down the Bamberton shore glued to structure until they hit Sheppard
Point. Conventional wisdom would have them bear right and thence to Stone Steps
and McCurdy Point.
When I started fishing in the ‘70s, I
would turn that corner, avoiding the reef that veered out from Sheppard between
the two points to try and catch your gear. Often I would see the old timers
simply carry on in a straight line and cross Squally Reach aimed directly at
the other side and McKenzie Bay (Saanich regulars did not go by the ‘correct’
name of McKenzie Bight).
I thought it was because they were
fishing a full spread of Peetz wire-line rods and it was easier to go in a
straight line, crossing the fishless deep water, and then pick up structure and
fish on the McKenzie side. But I was corrected and told that chinook often
simply went in a straight line there and crossed the deep water, that, in fact,
they caught lots of fish ‘high’ in the water way above the 700 foot depths.
In other words, instead of following
structure, the fish did not change direction and crossed deep water with no
relation to structure. I did not receive a good reason, only that they did so,
and so I picked it up and, yes, caught fish in mid-channel unrelated to
structure.
One explanation seems reasonable to me,
but there would be more. In March to early May, some years Chinook in the 16-
to 22-pound range came into the Inlet and seemed to follow it, swimming around
the structure from top to bottom. My SS Guppy II 24-pounder was one of those
fish. After several years of our catching them and giving creel reports and
heads, DFO eliminated retention for those fish in Saanich and anglers were not
impressed.
It turned out these fish were from the
north and south Nooksack and Samish rivers in Puget Sound, a genetic pool the
Americans were trying to save – and Victoria Waterfront retention was also
closed for this reason. The behaviour we saw was crossing deep water, and
circling the perimeter, but not leaving.
The best explanation is that, as Jimmy
Gilbert and Charlie White put it, Saanich Inlet is a giant, natural fish trap. Wain
Rock to Cherry Point is the opening, and fish migrating south simply pass into
what is an 18 mile long ‘trap’. Genetics made them stay deep in the inlet,
milling around, and not think to migrate back 18 miles to the north to get out
of the trap and off south to Puget Sound. That made them available for a long
time for anglers, and it was well known that they would migrate the perimeter
and each successive day’s angling was hottest ahead of yesterday’s hotspot.
The same structureless pattern often
happens in September. The Cowichan chinook, and, more-so, coho, can be found in
Squally at 250 feet mid-channel, particularly on blue-sky high-pressure dog
days of summer. Still prevails. That is why there is a closure in the Inlet –
to protect the remaining Cowichan fish.
Another example is where migrating
chinook cross deep water pushed by their genes. Some years ago, a young angler
in the Pink Salmon Festival received the biggest fish of his life almost out in
the shipping lanes, fishing with pink hootchies for pink salmon high in the
water. That fish was likely crossing Juan de Fuca to a Puget Sound river. The
same pattern prevails for chinook that hit Tumbo reef off Saturna or Active
Pass. There is thirty miles of deep water that must be crossed to get to the
Fraser River side.
Now, the fishing in deep water would set
up a fish highway that you could follow by GPS marks, provided there was only one opening on our side of
Georgia. Let’s say only Active Pass existed. It would pass all the fish, tens
of thousands in a summer.
Finally, this phenomenon exists even
though chinook tend to stick to shore in the last 100 miles from home. Our late
chinook, the white Harrisons, are typically Island Outfitters leader board fish
in September, into the forties. They are caught on the Owen Point ledge at Port
Renfrew that is a stone’s throw to shore – ditto for Aldridge and Creyke points,
also flood tide waters, in Sooke – even though when passing into Georgia they cross
deep water unrelated to structure.
One last thing: I have often caught
chinook absolutely perpendicular to a point of land. McCurdy Point and Trial
Island are such examples. Tide pushes quicker passing round a horizontal point,
and one would expect the fish to be swept into the downstream eddy. But darned
if they aren’t in the faster water off a point. So fish past a point rather
than hauling your lines and moving, on days the tide will let you pass the
point; days when it won’t, don’t waste time trying to get by, just move.
