Drones, Algae and Fish Ears: What We’re Learning Before the World’s Largest Dam-removal Project — and What We Could Miss

Scientists studying conditions on the Klamath River hope to help recovery efforts here and around the world, but they still lack dedicated funding.

Oceans & Clean Water

HAPPY CAMP, Calif.— Laurel Genzoli is trying to psych herself up to change into shorts, grab her kayak and head to the banks of the Klamath River. But it’s cold — somewhere in the 40s. Summer has swung quickly to fall, and the sun is fighting a losing battle with the thick morning mist that has blotted out the triangle tops of the pine trees.

But cold or not, it must be done.

It’s late September, and Genzoli, an aquatic ecologist, is wrapping up a last day of “summer” research on the Klamath River in Northern California. The day’s task, which begins at a campground in the small town of Happy Camp, is collecting dissolved oxygen sensors that she’s covertly left at seven different locations along more than 100 miles of river, which have been gathering data all season.

The information she’s collecting is part of her research for a Ph.D. at the University of Montana, but it’s also part of a much bigger scientific effort involving multiple state and federal agencies, tribal scientists and other university researchers.

Genzoli carries her kayak to the river.

They’re on a tight deadline.

The Klamath is a river in peril, plagued by dangerously poor water quality and collapsing salmon populations. That could start to change as early as 2022, when four dams are likely come down on the river — the biggest dam-removal and river-restoration project in history. Dam removal is expected to help solve many, but not all, of the river’s challenges, and understanding the change that does happen is crucial to planning the next steps for improving the river’s health.
