• Spawning Habitat is Extremely Limited in Lower Lake Creek– Of 34 transects:
• 19 have spawning habitat• 15 do not
– In the Anadromous Zone (Study Sites 1 & 2)• 4/9 in Study Site 1 have spawning substrate• 3/11 in Study Site 2 have spawning substrate

Analysis Method• Selected potential spawning transects in

Flow WSE was set to HSI of 0.9 to 1.0• Remaining transects had original substrate• All transects kept original weighting• Results reflect All transects in SS (not only
enhanced)

What Looks Promising• Increase spawning habitat
– Reaches 1 (anadromous)• Placement of LWD structures to retain gravel• If needed, gravel recruitment stations• Monitoring enhancement to verify usefulness• Monitoring accretion to verify variation of inflow
What Looks Promising
• Other Benefits– Added LWD = better rearing (cover &
hydraulic complexity)– Added LWD = better holding for spawners
(cover & depth)– Added LWD = more hydraulic jumps, more
frequent and deeper pools– Added Boulder Clusters = better rearing
(cover & hydraulic complexity)
