Skeena R discharge & sockeye

Comparing 2007 w 2006

‘What will the sockeye think’?

Maximum (1948?) and mean imposed over ‘Real Time’ at Usk

Some net fishers hope the Skeena sockeye run will be larger than predicted this year – they believe the ‘main run’ holding offshore because of the exceptional (for late July) high water in Skeena from snow melt.

Elsewhere I have shown June 2007 ocean temps cooler than anytime since 2001 --- but sequence similar to ‘tracking’ 2006

 

 

Cool Spring kept snow pack on mountains

In terms of 2006 Skeena R snow melt came later and higher than 2006 (itself an atypical year (La Nina) – here is my 2006 report

 

How atypical are large flows in July

This is from long term data series available on this web site --- I have plotted June, July, and August. July 1976 had late snow melt and might be analogous to July 2007 – note the periods of low water 1978-1983 in August

It would be interesting to ‘see’ if had effect on any Skeena Salmon runs

 

As said before I find Fraser R at Hope to be similar to Usk

Note the July 1976 ‘signal’ is seen on Fraser too. But record ‘late’ freshet seems to be in July 1920, which again might be analog to July 2007

 

 

Here is a previous July 2000 look at Sockeye run timing the fishery and Skeena discharge

And here is page for Skeena discharge dating from 2000

Environment Canada site has the River discharge ‘real time’

 

Conclusions?

This page is simply looking for patterns in relevant databases --- we would have to impose upon the data gillnet and seine catches (as in 2000 page) to take further step and see how affecting timing etc – (if signal were strong enough)
