Without intervention, poor fish
and wildlife habitat conditions will
persist, conceivably for centuries
REHABILITATION GOALS
FOR RESURRECTION CREEK
To recover fish and wildlife habitat
by rehabilitating :
• Historic floodplain
• Stream channels
• Riparian areas
14
Increase flood prone to bankfull width ratio
from 1:1 to >6:1.
• Decrease channel slope from 1.7% to 1.3%
• Increase sinuosity from 1.1 to 1.4.
• Increase channel length by 15%
15
Restore fish habitat by increasing:
Restore Fish Habitat
• Pools from 3 to 23 per river mile
• Side channel flow from <1% to 20%.
• Large in-stream wood from 8 to 330
pieces/river mile
• Spawning gravel from 160 to 2,000 yd²
per river mile
Flood Plains &
Riparian Vegetation
• Restore soil to the floodplain.
• Decrease riparian tree densities (thin)
• Restore tree composition to:
¾50% spruce
¾40% cottonwood
¾10% birch and hemlock
• Reestablish ground cover.
16
Restore wildlife habitat by increasing:
• Floodplain coarse wood from 16 to 120 pieces / acre
• Snags from 2 to ~10 per acre
LONG TERM OBJECTIVES
>100 YEARS
Restore the riparian forest to a
mix of old and young trees

NOTES:
1) Excavate toe log trenches perpendicular to flow and into bank below bed
surface at maximum predicted scour depth. 2) Excavate torsion Log trenches 15
&20% to flow and to bed surface elevation. Top of torsion log elevation should
exceed 3-5 year discharge return interval elevation. 3) Place weave additional
trees, logs, large boulders, slash or root-wads in apex of structure. 4) Place ample
slash and small woody debris on the up-stream bank interface of the structure.
