Occasionally I will hear from someone promoting algae from
Klamath Lake (Oregon) that the lake is "pristine" or
"volcano fed".  The reality is that it is eutrophic (dying),
and polluted with runoff from local agriculture. Here's a
quote from a recent article on the subject:

"Saving Klamath Lake: the solution that could slip away"
by Blake Edgar
Published in "Forefront", Spring 2003 issue. Published by the
College of Engineering, University of California, Berkeley, pp. 10-11.

Quotes:

"Snowmelt flowing to the flat high desert of the Klamath Basin once
fed a network of marshes and shallow lakes. Nearly a century ago,
this region that spans the California-Oregon border was chosen for
an ambitious federal farming effort. Dams were erected and canals
excavated. Today, this massive Klamath Project provides crucial water
for cattle ranchers and farmers of potatoes, onions, and alfalfa
on 230,000 acres."

...

"For now, though, no technology exists to detoxify the lake's
sediments."
