Threat to Lake Almanor & Butt Valley Reservoir
A diverse coalition of Northern California residents and the Almanor Fishing Association is taking on the role of
environmental protector by opposing a proposal to withdraw huge quantities of cold water from 90-year old Lake Almanor.
Serious damage to the environment and fishery at Lake Almanor and the nearby Butt Valley Reservoir will occur. Both these
lakes have developed reputations for trophy Rainbow Trout and German Brown.
In the case of Butt Valley Reservoir, trophy trout there feed on the pond smelt that pass through the Prattville intake tunnel. The thermal curtain would severely reduce the pond smelt and have a negative impact on the trout food supply in the reservoir.
Also, PG&E intends to install two thermal curtains to hold the cold water pumped from Lake Almanor which could possibly
damage not only the fishery but the very important insect hatches and lake environment.
At Lake Almanor, the removal of cold water – up to 50% during the summer months according to PG&E – would push the
“thermocline” (where trout favor the temperature) down about 10 feet, forcing the salmonids (trout & salmon) into an area
nearer the bottom where the dissolved oxygen is inadequate. Currently, when the lake temperatures increase, the fish
migrate to the colder springs and into the rivers flowing into the lake at the north and northwest ends of the lake. The studies
conducted in June reported that even now dead salmonids are seen near springs, leading to concerns that the area is already
insufficient to support the fish migrating to seek colder water during summer. The lake's famous and very important “hex
hatch” could be compromised.
THE FIGHT IS NOT OVER YET !!!!!
BUT WE'RE WINNING WITH YOUR SUPPORT !!!!!
