CREATING
NEW INLET
A
new inlet will be constructed 200 feet upstream of the boat ramp at Clearwater
Park and will
flow through part of an old channel of the Middle Fork of the Willamette.
The new inlet will enhance water flow through the Mill Race and improve
habitats for fish and wildlife.

REMOVAL OF MILL POND DAM
The Mill Pond will be drained as much as possible
through the dam outlet and then a diversion
structure will be placed just upstream of the Mill Pond area to divert
the Mill Race flow through a pipe around the Mill Pond.
The pond area will then be graded to construct a meandering channel with
connecting seasonal ponds. Excavated soil will be placed along the banks
to provide a gentle slope for riparian and wetland plantings. Approximately
20 acres of wetlands will be created in the Mill Pond area.
The removal of the dam will provide better water flow along the course
of the Mill Race and allow safe use of this aquatic habitat by many types of fish, including Spring
Chinook salmon.

REMOVING
INVASIVE PLANTS
Non-native
plants such as blackberries and reed canary grass have choked out
many of the native plants along the Mill Race. Removing these invasive
plants and allowing regrowth of native plants will encourage repopulation
of native wildlife. |

RESTORING
RIPARIAN AND WETLAND HABITAT
After removing
invasive species, native plants will be cultivated along the Mill
Race banks and new wetlands will be established at the former Mill
Pond site.
The existing young deciduous forest buffer will be enhanced by planting
conifers and other native species for about 100 feet on each side
of the new channel on public land adjacent to the Mill Race.
Wildlife such as western pond turtles, red-legged frogs, migratory
birds, beaver, otter, and waterfowl will benefit from the created
riparian and aquatic habitat.
