Federal Tax ID The volcanoes, earthquakes, and crumpled mountain chains, that border the Pacific, are the result of buckling edges of great plates of the Earth's crust under compression. Upper Klamath Lake is free of adverse bacteria, heavy metals, pesticides, herbicides, insecticides and fungicides.

The lake receives an average days of sunlight per year which provides a perfect growing environment for the world's richest strain of wild AFA blue-green algae, scientifically known as Aphanizomenon flos-aquae.

The alkaline lake water provides more than 60 times the nutrients needed for the algae to grow to its full potential each year. Under the right conditions, AFA algae can reproduce every 20 minutes, which provides a plentiful abundance of this organic, high life-force, miracle super food.

The dam has a height of 7 meters 23 feet. Most of the wetlands that used to surround the lake were drained in the early 20th century for agricultural purposes, damaging the wildlife and habitat. Before the 20th century when the marshes and wetlands were drained, the region supported abundant wildlife. The wetlands also used to protect water quality in the Upper Klamath Lake. Since many of these critical habitats were drained, the lake went from eutrophic to hypereutrophic, due to more nutrients coming to the lake from agricultural runoff.

This resulted in blue-green algae blooms on the lake. By turning the water into an opaque green color, these algae blooms reduce recreational activities on the lake. The dominant alga is Aphanizomenon flos-aquae, a blue-green alga which forms large colonies.

It begins to appear in late spring and continues to increase by late summer. In early fall, these algae die, and the decomposition of the large biomass leads to the depletion of dissolved oxygen and unpleasant odors. Another cause for concern is the amount of dissolved oxygen in the lake: the state standards are violated on a regular basis, which means that fish are endangered as well.

The hypereutrophic state also leads to an overabundance of midges, which swarm and are a serious nuisance to people around the lake. In , due to this decline in water quality, the US Fish and Wildlife Service FWS put the shortnose sucker and the Lost River sucker, two fish species that used to be abundant in Upper Klamath Lake, on the federal endangered species list.

Consequently, a dredging project that would have damaged water quality even more was abandoned by the government. In the summer of the entire Oregon was in a drought, which increased environmental concerns about the lake.

To protect the sucker population, the BOR stopped withdrawing water from the lake, which resulted in protests from the farming community. Starting with , the FWS monitors the lake regularly because of water shortfalls, which not only endanger fish in the Upper Klamath Lake, but salmon in the Klamath River as well. The future of Upper Klamath Lake is of national interest, because of the conflict between farmers who are supported by federal subsidies and programs and environmental groups.
