According to the plan, PacifiCorp would transfer ownership of the dams to the newly formed Klamath River Renewal Corporation, which would tear down the dams with funds from the power utility and the state of California. “If PacifiCorp wanted to try to keep their dams and get a new license, they would have to somehow mitigate these algal blooms to the point where they were compliant with the Clean Water Act, and they weren’t sure how they could possibly do that,” Tucker said.

The toxins produced by freshwater blue-green algae do not appear to bioaccumulate in fish and other edible aquatic life in lakes and rivers to the degree that they can in some seafood. On sites that are prone to BGA blooms, we work with the Environment Agency and others to try to identify ways to reduce this in the future. The UK Centre for Ecology and Hydrology have a range of images showing the different forms. Unfortunately there is no way of knowing which clumps of BGA are going to produce toxins and which aren’t. Healing the Klamath means unspooling the bitter legacy of manifest destiny, and returning the river to a more natural state. The outcome of this risk assessment helps us to create a monitoring regime, which varies from weekly visual inspections to taking daily oxygen readings if it’s a site we’re particularly worried about. Parties say they are optimistic that they will be able to keep PacifiCorp on board, given the much steeper cost of continuing to operate the dams. This made it harder for the regional power utility, PacifiCorp, to continue operating the hydroelectric dams that were fueling the algal blooms. “These reservoirs have become liver toxin factories, just pumping this stuff out.”. “I would like everyone who has had a stake in this process to recognize that our way of life and our connection to our place and to our relatives and our identity as a people is at stake,” Saxon said. “This isn’t our livelihood. “Every day, I pray for clean water, and it’s just disheartening when you go outside, and you smell that smell, and you see the river,” Saxon said.

The microorganisms that gobble up cyanobacteria remains consume huge volumes of oxygen during their feast, leaving fish to suffocate. This can drastically reduce the amount of oxygen available for fish and other aquatic creatures, which sometimes kills them. “In terms of large-scale policy, there isn’t right now any explicit policy in California that’s addressing the drivers of harmful algal blooms,” said Keith Bouma-Gregson, an environmental scientist who co-leads the freshwater harmful algal bloom program for the California Water Resources Control Board.
