Scientists suspect heat stress killed thousands of salmon in Alaska's Koyukuk River last month.

Scientists believe heat stress killed thousands of salmon in an Alaskan river last month.

From July 7 to 11, communities along the Koyukuk River experienced sustained air temperatures of over 30 C, well above the seasonal average highs of less than 20 C.

Shortly after the heat wave, locals began reporting an unusual number of dead chum salmon washing up on the banks of the river.

Thousands.  Does that mean anything in context?  I remember a report that in the one mile south of the Coralville Dam on the Iowa River there were an estimated 450,000 carp.  Killing "thousands" (or all of them) wouldn't even amount to a good start.

BTW, from the article...

Many chum salmon made it to their spawning grounds this year and it's not expected the deaths will have a drastic impact on the overall population.

In the mean time... The PacNW and Northern Rockies are enjoying a cooler than normal summer... Here in MT, my yard is still green and growing, and for the first time in a decade, August was not 'Smoke Month'

So much for their assertions.

And the survivors will breed a new generation that's more heat-tolerant...

Observing the same in North Dakota. We get rain almost daily, temps have not gone over the lower 90s, everything is still green. Looks like we'll get a second picking of Raspberries, too.
