Projects & Plans
Hemlock Dam
Fish Passage and Aquatic Habitat
Restoration Project
The
Mt. Adams Ranger District of the Gifford Pinchot National Forest proposes
to remove Hemlock Dam, and to restore the Trout Creek channel in the area
that is now occupied by the dam and reservoir. Trout Creek is a tributary
to the Wind River in Southwest Washington, and supports Lower Columbia
River Steelhead that were listed as Threatened in 1998. The proposed action
is needed to improve upstream and downstream fish passage for all life
stages of fish at the Hemlock Dam site and to improve aquatic habitat
and water quality in Trout Creek.
Alternatives
Issues
raised during the scoping process led the agency to develop and analyze
the following alternatives:
Alternative A
-- No Action
Alternative B -- Remove the dam and let the river erode
sediments in the reservoir
Alternative C -- Remove the dam and dredge all sediments
from proposed channel location
Alternative D -- Retain the dam, improve deficiencies,
and modify or replace the fish ladder
Alternative E -- Retain the dam, improve deficiencies,
do not modify or replace the fish ladder
