3. HISTORY Due to channelization in the 1950’s, Okanagan River has been reduced by 15 miles/24km and only 4.3miles/ 7 km remain in a natural state
Managed dykes have reduced riparian area and associated vegetation by 88%
CCT and ONFC propose to develop a plan to prioritize restoration options of the 17km of channelized sections that will increase salmon habitat
4. OKANAGAN SOCKEYE
Okanagan River supports 50% of the remaining sockeye production in the Columbia Basin
Canadian Fisheries Authorities estimate less than 5000 sockeye will return to the Canadian mainstem to spawn in 2003
Okanagan Sockeye is a candidate for COSEWIC listing
5. SALMON RECOVERY GOALS
Provide a long-term vision for the river and options for implementation through habitat protection and restoration
The plan will be based on a long-term self-sustaining ecosystem approach that emphasizes natural processes and benefits all species
6. PROPOSAL OBJECTIVES Create a plan to restore the channelized section of the Okanagan River to produce an increase in sockeye salmon habitat that will outline:
Identified protection and restoration locations and methods
Prioritized areas for restoration
Benefits, costs, risks and steps required for implementation
7. PROJECT DESCRIPTION Compile and record relevant information and knowledge
Rank options for protecting and restoring river habitat with costs, benefits and risks of each option considered
Fisheries Authorities and critical stakeholders will prioritize the options
Finalize the plan
8. OBJECTIVES Long-term self-sustaining ecosystem based approach that emphasizes natural methods and benefits all species
Habitat Plan will interconnect the various initiatives currently underway
Provide a conceptual foundation so work can be carried out in a logical manner
9. PROJECTED OUTCOMES FROM HABITAT PLAN Secure riparian parcels to set back or remove dykes
Replace existing VDS with rock pool/riffle complexes to develop spawning platforms
Add riparian vegetation and habitat complexing with LWD
After initial implementation, complex habitat would develop naturally, spawning gravels would be collected and silts redistributed to floodplains
10. BENEFITS TO SOCKEYE Reduced velocity and increased hydrological variability
More natural migration route
Additional spawning areas
Provide escape and cover
11. PARTNERSHIPS
ONFC and CCT have been working cooperatively in salmon restoration partnerships
Okanagan Basin Technical Working Group (OBTWG) – Okanagan Nation Fisheries Commission, Department of Fisheries and Oceans, Ministry of Water, Land and Air Protection
OBTWG and Douglas County Public Utility District working cooperatively on habitat restoration and mitigation projects
