Project Description 12

Project Description Cooperate with landowners to vegetate riparian zones, improving diversity and function, providing shade and preventing stream bank erosion. 13

Project Description Replace the pushup irrigation diversion and stabilize the headcut structure to improve adult and juvenile salmon, steelhead and bull trout passage. 14

Project Description Place root wads, anchored logs, J-hooks and W-weirs to provide safe migration corridors by reducing channel gradient, prevent channel migration, and provide stream bank erosion protection thereby reducing sedimentation. 15

Project Description Educate landowners on management practices that will enhance riparian zones. 16

Project Description Pursue Phase II - Next mile downstream to the Island City Bridge 17

Future Without Project Headcut Could Break Free Resulting in the Following: 22

Future Without Project Severe Headward Channel Downcutting Loss of Channel Complexity Continued Riparian Habitat Degradation Loss of Spruce Street Bridge Massive Sediment Movement and Entrapment (gravel bars) 23
