A Summary of Environmental Issues that Plague the
Upper Klamath Basin

Abstract
Environmental problems have existed in the Klamath Basin since the late 1980s,
when select fish species were listed as endangered species. Fisheries decline
was exacerbated in 2002, when a large population of sixty thousand fish was
killed trying to migrate to their spawning grounds. One of the reasons is that dams
have been put on the rivers in the Klamath Basin, however no water ways were
made for fish passages. Not only fish are being affected, but also the birds that
use the local wildlife refuge are dying because there is not enough water to
support their migration south
INTRODUCTION
•Since the 1980’ there have been many problems in the Klamath Basin such as
water rights, environmental issues, species going on the endangered list, also
irrigation problems, and very importantly water quality.
During
2001 farmers were out raged because water was not given to a lot of
farmers and the reason was that their was not enough water in the Upper Klamath
Basin to keep water levels normal.
•The reason that fish and wildlife are going on the endangered list is because of
the water in the Klamath Basin. The chemical composition, algae, and water
temperature are the main concerns.
The
farmers protested in Klamath Falls which became the largest cultural event
in the history of Klamath Falls.
•The chemical composition is due to large part from the volcanic soil in the region
which contributes to the high phosphorous and nitrogen in the water.
The
•The green algae and diatoms that are in the Klamath Basin give rise to algal
blooms in the late summer and these blooms will dissolve the oxygen and pH
levels in the water. The fish need the oxygen and pH levels higher to survive.
government eventually gave in because of lawsuits by the farmers and the
water was restored to the farmers which was a mistake.
In
2002 over 60,000 fish died making their way up to spawning grounds in order
to lay eggs.
The
reason the fish died was because a lot of water was used the previous year
and with drought like conditions their was little water in the snow pack and
reservoirs the water level was dangerously low and their were toxins in the water
that killed the fish.
Basic Overview of Water Rights
In 1864 the Native Americans made a deal with the United States government to
70,000 acres of land in order to secure water rights and also to be able to fish
along the banks of the rivers in the basin.
Water quality in the Klamath Basin
Largest Fish Kill Ever in the United States
•The temperature has been increasing for several decades in because of loss of
vegetation along streams and river channels. The loss of vegetation is caused by
many factors such as logging along stream beds, livestock eating the vegetation,
housing developments, and road construction
Another
contributor was that dams were put on the rivers in the Klamath Basin in
1917, these dams were required to have fish passages for the fish to travel
through the dam, however the dams did not have these fish passages installed
and the fish cannot migrate up the river.
Also
the people that came out on the Oregon trail were promised land and all the
water they needed to be able to grow crops.
Now
the state not the government is giving farmers in Oregon permits to use the
water, and there are more than 1000 farmers with these permits.
Last,
the wild life refuge is also needing the water because many birds fly over
and stop at the refuge to use the water.

The Irrigation Problem
Endangered Species
•In 1905 an authorization was given to use another source of water rather using
the snow pack the government started to use a different source of water.
•In order for the land to be used for farming the government had to dike and I
irrigated the flood plain that would accumulate water every spring.
•Another problem was that when the settlers came to farm the land had a desert
setting and the government needed to change the setting, therefore the irrigation
was necessary at that time.
In
1988 the Native Americans became upset when a few of the
fish that they use as a food source are put on the endangered
species list.
Also
salmon fishing was closed earlier than expected because
of the low numbers of fish that were traveling up into the Klamath
Basin.
Conclusions
Many of the problems could have been avoided, however now the government
is now trying to fix this mistake before it has the chance to get worse.
•
Also because of the fish kill a lot of businesses along the Oregon coast have
had 90% set backs in there fishing and crabbing.
•
Also the Government is looking to take some of the dams off of the rivers,
however there are too many unknowns of what could happen if they were
