Our Klamath Basin
Upholding rural Americans' rights to grow food,
own property, and caretake our wildlife and natural resources.
Research Council Chairman Dr William Lewis Jr., University of
Colorado, spoke regarding the NRC conclusions on suckers....Lewis
explained that the suckers were listed since 1988 because of over
harvest. They stopped fishing in '87 but they did not
recover. The lake has gone from 3' range under natural conditions to
experiencing 6' deep in current dry years.
|With charts and graphs he showed
the habitat and water quality, algae and
chlorophyll. He said that the committee looked
extensively at water levels, and they find 'no hint
of a relationship'. He also said that there was no
relationship between lower water levels and extreme
ph levels. And "the committee cannot support the
idea that water levels effect algae growth.' "It can
not be achieved by lake levels." '92 was the lowest
water year, and they expected it to be the least
favorable for fish. 'The lowest water year produced
the same amount of larvae as other years."...
He said that fish kill information does not support that fish are
dying by changing water level...
He cautioned how much faith we should put into
wetlands regarding the suppression of algae...
He added that we should not count on retiring
agricultural land land for saving suckers...
Lewis responded that the water is always ph loaded,
"the increase doesn't matter if it's always been saturated."...
When asked if it would work to control the
significant part of the ph load, Lewis responded that the lake is
140 square miles...that is not feasible to change....
Tribal biologist Larry Dunsmuir felt
like lake level management was necessary for
emergent vegetation, and Lewis responded that Clear
Lake has no emergent vegetation yet production of
larvae is not shut off in Clear Lake.
