This just in from CalTrout - Klamath River Flows [
Ed: just below Iron Gate dam] will see a significant spike tomorrow (Wednesday).
And it turns out, it's maybe for a good cause (ridding salmon of parasites):
Flows will rise from from base of 1600 cfs to 5000 cfs and back to 1600 cfs between noon and midnight Wednesday. These flows are designed to flush fine sediments that harbor polycheate worms"”the intermediate hosts for fish parasites such as Ceratomyxa shasta. As most of you are aware, a large percentage of outmigrating juvenile salmon are infected with parasites which can be lethal.
This flow change is a result of the Klamath Settlement Agreements and in particular the ability to more flexibly manage the river.
