We're camping along the Chetco River in Oregon and noticed a lot of algae in the water and on the river banks. This surprised me because the river, though not really swift, is in constant motion. I thought algae blooms were still-water phenomena.
Anyway, did some Googling and found that dangerous blue-green algae (actually a bacteria called Cyanobacteria) blooms occur in this area, and I guess all over, typically from June through September. This algae can be especially dangerous for pets that swim in it. However, found a simple blue-green algae test, but also want to know if anyone has run across this stuff in their travels.
