Klamath Blue Green Algae is a wild, fresh water algae growing in natural abundance in Upper Klamath Lake. The precipitation that falls on the Southern Oregon Cascade Mountains washes tons of mineral-rich volcanic soil into the alkaline lake annually. This mineral-rich water, clean air, and high intensity sunlight make the unique ecosystem of Upper Klamath Lake the most perfect growth medium for A.F.A. Klamath Blue Green Algae is a naturally occurring perennial. Its survival depends on the heartiest strain reproducing itself, and its uncanny ability to communicate environmental and other conditions to each strand in the bloom.
