Mission—To restore and protect the natural, cultural, and historic resources of the Sandy River basin

SLIDE 3

Sandy River Basin Partners

SLIDE 4

State of the Sandy

 10 year progress review: Dam removal;

restoration; fish; people

 ‘Seven steps’ toward a healthy future

SLIDE 5

Sandy Undammed

SLIDE 6

Restoration Actions

 Prioritized sub-

basins

 Actions

addressing limiting factors

 In-stream

complexity, riparian, passage/floodpla in connectivity,

thers

SLIDE 7

Sandy and the Estuary

 Sandy Delta (

among working partners)

 Oxbow side

channels (sea lions reported)

 Beaver Creek

Partnership and Mt Hood Community College Salmon Safe Retrofit

SLIDE 8

Subbasin Priority:

Salmon River

 2.1 side channel

miles restored in 2.5 mile reach

 67 logjams,

~2000 large wood pieces

 Increased

juvenile, spawning densities

SLIDE 9

Subbasin Priority:

Still Creek

SLIDE 10

Monitoring:

Biological (+ social) Response

Missing Pieces

 Stream

temperature profiles

 Sub-basin adult

return analyses

 Demographics:

distribution, age, ethnicity

Seven Steps:

Coping with Urban Impacts

MHCC Salmon Safe Retrofit 24 projects 1 Billion gallon intercept goal

SLIDE 20

Seven Steps:

Climate Adaptation

SLIDE 21

Hydrology 2080



Shifting snow levels – 8% snow dominant vs 45% current



20+% increased storm intensity



Additional debris from retreating glaciers



Infrastructure risk: 450 houses w/in channel migration hazard zone

SLIDE 22

Seven Steps:

Climate Adaptation This Week

SLIDE 23

Cold Water Refuge

 EPA study: Sandy

2-3 degrees cooler than Columbia

 CRITFC study:

intensive instream +riparian planting can temper climatic stream heating

 Conservation plan

under development

Median temperature change (Climate + Veg + Width) = -2 °C Justice, White and McCullough
