Icicle Creek Salmon Habitat Conditions* Land Development has affected stream channel movement, off channel habitat, and LWD recruitment. Barriers to migration exist at the Leavenworth Hatchery and possibly at the Snow Creek boulder field. Water withdrawals may contribute to low flow and high summer temperature in lower Icicle Creek. Forest fires have caused increased sedimentation and water temperature in the middle and lower Icicle drainage. *Paraphrased from the Upper Columbia Salmon Recovery Board’s Biological Strategy (22 May 2003)

Salmon Recovery in Icicle Creek Enhance Channel Movement: Increase stream sinuosity and decrease entrenchment (meander reconstruction) Add LWD in the form of rootwads, log jams, and similar structures that mimic natural formations Decommission, modify, or relocate roads, low- priority dikes, bridges and culverts Protect Channel Movement: Follow existing land use and instream work regulations that limit riparian area, floodplain and wetland development Educate the public on the importance of stream channel movement Allow stream channels to develop and flood naturally Manage stormwater runoff from existing and new development and road construction using detention, treatment and infiltration measures

Salmon Recovery in Icicle Creek Enhance Fish Passage Remove, replace, or modify diversion dams Remove or replace culverts Use cost-sharing programs to help landowners screen diversions. Apply BMPs to forest practices Create spawning/rearing/overwintering channels or habitats Remove one or more dams Upgrade stream crossings Remove natural barriers to fish migration Protect Fish Passage Prevent new passage problems Design and construct road culverts consistent with standards and guidelines. Use permits or other approval mechanisms to impose design and construction restrictions on activities that may impede fish passage and access.

Salmon Recovery in Icicle Creek Protect Flow Levels: Establish in-stream flows in priority rivers and streams and uphold them when established Protect and maintain established instream flows by monitoring water use and enforcing laws and regulations. Administer groundwater and surface water right permits and changes consistent with the to-be-established instream flow. Protect groundwater recharge areas from impacts of land development Manage recreation areas to reduce or avoid impacts to riparian habitats

Salmon Recovery in Icicle Creek Enhance Water Temperature Enhance stream form and function Fence livestock out of riparian areas Manage stormwater and road runoff TMDL process (Water Clean Up Plan) Improve riparian buffers Decrease the streams width-to-depth ratio Follow existing regulations Decommission, modify or relocate roads, low-priority dikes, bridges, and culverts Restore perennial upland vegetation Minimize surface water withdrawals through: –implementation of irrigation efficiencies, –quantify legal withdrawals, –identify and eliminate illegal withdrawals, –Lease/purchase of water rights Improve upland water infiltration through: – road decommissioning, –reduced soil compaction, –direct seeding activities, –increasing native vegetation cover Conduct shade restoration activities Enhance wetlands and wet meadows Enhance spring inputs to streams Assess and remedy significant sources of high- temperature inputs to surface waters

Salmon Recovery in Icicle Creek Protect Water Temperature Use State Environmental Policy Act (SEPA) to prevent, minimize or mitigate both immediate and long-term impacts. Implement forest practices regulations. Establish and protect riparian buffers Regulate vegetation removal Implement temperature Total Maximum Daily Loads (TMDLs) Use incentives and technical assistance to implement best management practices; Implement education and enforcement programs.

Salmon Recovery in Icicle Creek Improve sediment delivery Implement a road maintenance schedule Remove, reconstruct or upgrade roads where feasible Improve stream crossings, culverts and road drainage system Reconnect floodplains through dike removal or breaching; Implement in-channel projects Construct detention and infiltration ponds Reestablish natural riparian vegetation Protect sediment delivery In areas with unstable slopes, restrict: – development, –road construction, –logging and, –intensive farming Minimize road density, maintain existing roads Provide and maintain adequate drainage for new roads and existing roads Protect geologically hazardous areas Implement best management practices Avoid soil disturbance
