Dedicated to restoring and
maintaining a healthy
Stillaguamish River Watershed
since 1990

The mission of the Stillaguamish Watershed Council
(SWC) is to maintain a healthy, functioning Stillaguamish
Watershed by providing a local forum in which agencies,
organizations, communities, and the public can engage in a
collaborative watershed based process of decision making
and coordination.

Port Susan Bay Restoration
Sponsored by The Nature Conservancy

The Nature
Conservancy worked
for over 10 years to
design and implement
a dike removal and set
back project in Port
Susan Bay. As a
result, over 100 acres
has been returned to
tidal influence.

The Nature
Conservancy
removed the dike
labeled in red on this
map and built a
new, set back dike
along the area in
green. As a
result, over 100
acres has been
returned to tidal
influence, and is
providing new
habitat for fish and
shorebirds.

Stormwater Wetland Site
Sponsored by The City of Arlington

The City of Arlington's
new Stormwater Wetland is
an innovative new tertiary
treatment facility, designed
to filter out chemicals and
toxic substances before the
water is returned to the
Stillaguamish River.

Cherokee Creek Fish Passage Restoration
Sponsored by Stillaguamish Tribe of Indians

The Stillaguamish Tribe, in
conjunction with the Family
Forest Fish Passage
Program, replaced a culvert
that was blocking fish
passage on Cherokee Creek
with a new bridge. As a
result approximately 1 mile
of new habitat is now
accessible to all species of
Pacific salmon and trout.

Jim Creek Bank Restoration
Sponsored by the Stillaguamish Tribe of Indians

The Stillaguamish Tribe of
Indians sponsored a
riparian restoration project
on Jim Creek that involved
stabilizing a bank with
natural logs and
slash, planting a buffer
with native vegetation and
installing fencing that
keeps livestock out of the
creek. As a result, the
water in Jim Creek
downstream will be
clearer, cleaner, and more
friendly for fish.

North Fork Riparian Restoration

Indians, in conjunction with
Forterra, purchased and
restored about 35 acres on
the North Fork
Stillaguamish. Dilapidated
structures were demolished
and removed, and a riparian
buffer was planted with
native vegetation. The
Tribe has plans to install
engineered log jams at this
Location site in the future.

Blue Slough Reconnection

This project reconnected
2500 feet of remnant side
channel that has been
disconnected from the
mainstem North Fork
Stillaguamish since the
1930s. This project
removed a 2-3 foot layer
of "muck" and enough bed
material to put the channel
at the elevation of the
river. The final phase of
construction installed new
corrugated metal culverts
to connect the slough to
the river at both ends
allowing continuous flow
through the channel.

North Meander Reconnection Project
Sponsored by Snohomish County

The North Meander project
increases side-channel
slough habitat by 1.8
hectares - an increase of
18.5% over existing
amounts - or 8% of the
historical loss in lower
river, by reconnecting 3,300
feet of side channel. 300
pieces of large woody
debris were placed for
complex edge and cover. A
box culvert and a bridge
were installed to reconnect
the channel.

Eagle Creek Barrier Removal and Riparian Restoration
Sponsored by the City of Arlington
This project directly
addresses the degraded
conditions by working
with the private
landowner to repair and
restore the first 1000’
(12%) of the stream’s
riparian corridor, and to
provide for fish
passage to the upper
9000’ of stream
corridor through the
removal of two
collapsed culverts &
enhancement of native
riparian vegetation
largely with native
conifers and riparian
shrubs.

Riparian Enhancement Inmate Crew

The Stillaguamish Tribe has
partnered with the Snohomish
County Department of
Corrections to establish a
Riparian Enhancement Inmate
Crew. Minimum security
inmates participate in this
program, helping with a variety
of restoration projects
throughout our watershed. They
control dangerous invasive
weeds and plant thousands of
native plants each year.
