Filamentous algal bloom, no doubt. Flares up with any imbalance in nutrient load, low flows, warm flows.

The Wynoochee post was right on. This "toilet paper" stuff even happens in Alaska. Anybody fish the early run kings on the Kenai the first two weeks of June in 2001. Couldn't keep a back- trolled/bounced line in the water more than two minutes. One big Killey dump mid-month took care of it in a hurry.
