Riparian Habitat – Key Elements
• A mix of native trees and shrubs, typically adapted to seasonal flooding
such as: Oregon ash, cottonwood, red alder, red-osier dogwood, red
elderberry as well as sedges, rushes and ferns.
• Rocky outcrops including basalt outcrops and bluffs which provide
unique habitat for insects, amphibians, and rare plants.
Riparian Habitat Desired Outcomes
• Restore native trees and shrubs
along the Willamette
• Protect and restore rocky outcrops
by removing buildings and structures.
• Provide important habitat for
migratory birds and other wildlife.
• Improve water quality through
filtration, stormwater attenuation,
woody debris, and leaf litter inputs into
the river.

Protect and Restore Misty Rock Bluffs
Riparian Habitat link to other Key Goals
• Public Access:
Protection of rocky outcrops and riparian areas provide scenic views for the
public. Restoring native vegetation will provide a natural feeling to portions
of the highly developed site and increase wildlife watching opportunities.

• Cultural and Historic Interpretation:
Protection of rocky outcrops are likely to be areas of significant cultural
importance to the tribes.
Riparian Habitat link to other Key Goals
Native Fish Habitat
Key Elements
River shoreline with a
mixture of habitat
elements important for
native fish.
The Willamette Falls
area is the gateway for
all migratory fish.
Native Fish Habitat –Desired Outcomes
• Restore shoreline habitat
complexity, including
alcoves and inlets for cool
water refugia and off-
channel habitat during
periods of high river flow.
• Provide important resting
and movement habitat for
anadromous fish species.
Historic Shoreline
Tail Races
Alcoves
• Cultural and Historic Interpretation:
Salmon fishing and lamprey harvest
are culturally important to the tribes.
• Access: Interpreting salmon and
lamprey life cycles are likely to be key
parts of any interpretation program.
• Economic Development: Restoration
jobs could provide additional jobs and
revenue for the community.
Links to other Key Goals
Water Quality Key Elements
• Springs and seeps that provide
cold water input to the River.
• The 54 cfs water right could be
returned to in stream flows for water
quality and fish habitat.
• Surface water (primarily treated
stormwater) could provide additional
flows through historic side
channels and alcoves.
• Healthy water quality (clean and
cool water) is important to native
fish and other wildlife that use the
site.
Water Quality –Desired Outcomes
• Improve water temperature and chemistry above
existing conditions at the site.

A Quiet Day
Vision Report and Master Plan adopted last
night by Oregon City Council
Next Steps – Willamette River Walk
• Public access out to view
the Falls should happen
before anything else on
the former Blue Heron
mill site.
• Thus, the community and
project partners have
identified the opportunity
for a public walkway
along the Willamette
River
