When were the extreme temps causing poor survival?
I realize DFO has been cut back and are short staffed but why the late info?
Where have you been???? This not new. Look at the date on this notice:
Category(s):
RECREATIONAL - Salmon
Fishery Notice - Fisheries and Oceans Canada
Subject: FN0678-RECREATIONAL -Salmon - Non-retention of Coho and Chinook Salmon in Region 1 - Puntledge River
Coho and chinook salmon returns to the Puntledge River are forecast to be lower
than average in 2011. Local hatchery staff have indicated that hatchery coho
smolts experienced extremely high rearing mortality in 2008 due to high water
temperatures and unfavorable rearing conditions.
At this time returns are uncertain therefore the daily limit for coho and
chinook salmon will remain at zero (0) in the Puntledge River until further
notice.
This is an update to page 8 of the 2011-2013 BC Freshwater Salmon Supplement.

The hatchery has been battling high temperature kills for YEARS... thats why the endangered summer run chinook are incubated and reared at Rosewall. As far as the coho, in an attempt to offset losses in the upper Puntledge rearing channel, (just below the lake where it is greatly affected by warm surface temperatures) the hatchery changed their strategy and has cut thier smolt program drastically. More adult coho are allowed to spawn in the lake tributaries and fry hatched at the lower hatchery are released into the lake and inaccessible tributary streams to the lake. Fry have a much lower survival rate than hatchery smolts, so returns are almost impossible to predict with precision . But there is a limit to how many fry can be reared in the lake and streams adjacent to the lake. The Provincial Fisheries people have expressed concerns that too many coho may affect trout populations in the lake. That is still a discussion in progress.
The hatchery manager Darcy Miller is very approachable. If you want more info, give him a call at the hatchery and set up a time for a chat.
