Heat blamed for Klamath fish kill
Published Thursday July
Thousands of dead fish
were found belly up on the Klamath River
southwest of Klamath Falls this week, the
apparent victims of poor water conditions
brought on by hot weather.
Dead fish were found on
a seven-mile stretch of the Klamath River below
Lake Ewauna and in irrigation diversions on the
river. The number of dead suckers were estimated
to be "several thousand" suckers, said Rae
Olsen, Bureau spokeswoman.
Suckers can tolerate 75-degree water for quite some time, but it still harms their health, he said.
Fish die-offs are common
summertime occurrences that happen because of a
combination of low water and high temperatures.
When temperatures go up, the water quality goes
down because oxygen levels are lowered by
decaying algae, Smith said.
The die-off won't change
how much water the Bureau releases from Upper
Klamath Lake, Olsen said. Officials are required
to conserve water in Upper Klamath Lake, where
water quality is also poor and fish die-offs are
a possibility during the summer.
Only cooler temperatures
will help prevent fish die-offs. Temperatures
are expected to cool slightly over the weekend,
the National Weather Service said.
