1 Chelan County Lead Entity Presentation SRFB 2005 Salmon Habitat Grant Cycle

3 Upper Columbia Salmon Recovery Plan Lead Entity Strategy is the Salmon Recovery Plan Plan is draft and has been adopted by citizen committee Projects address needs identified in Plan Projects reflect restoration priorities in watershed plans Recovery Plan implementation strategy being developed

4 Chelan County Lead Entity Projects

5 Leavenworth Fish Screen Sponsored by City of Leavenworth SRFB Request $71,770 Tributary Fund Request $12,665 Project of Concern

10 Concern This project uses a technique that has not been considered successful in the past Response Discuss appropriate design

11 Questions?

12 Gagnon Property Off Channel Habitat Project Sponsored by Chelan County Natural Resources Department SRFB Request $366,325 Tributary Fund Request $65,000 Project of Concern

13 Objective The Gagnon Project reduces habitat limiting factors by creating approximately.56 acres of off- channel high-flow (>3,000 cfs) refuge and rearing habitat while connecting 0.5 acres of currently isolated high-flow habitat; directly benefiting juvenile Chinook, Steelhead, and Coho. The project also includes 1.39 acres of riparian restoration.

15 Site Location

16 Concern The application should state that as part of the project a pump test will be done to confirm the presence of sufficient hyporheic flow to support flow at the alcove outlet Response A pump test will be conducted

17 Concern The applicant is strongly encouraged to do rigorous monitoring throughout the year to determine fish use Response Chelan County in coordination with the RTT are currently preparing project monitoring protocols

18 Concern Pond photos in report indicate high probability of temperature and DO problems during summer. Are there water quality problems in the pond? Response Water quality will be sampled during the pump test Elevated water temperatures or DO due to ponding are expected to lower following the completion of the perc channel

19 Concern Will predation be an issue? Response The pond has been designed to avoid fish stranding The riparian planting component of this project will restore 1.39 acres of riparian habitat to back channel habitats providing cover and refuge from predators.

20 Concern An overall concern exists with all of the off-channel projects being considered in the lower Wenatchee River because they appear to provide short-term engineered solutions Response Chelan County watershed wide restoration approach

21 Questions?

22 Entiat Instream Habitat Improvements Sponsored by Chelan County Natural Resources Department SRFB Request $212,500 Tributary Fund Request $37,500 Not a Project of Concern

23 Nason Creek Oxbow Reconnection Project Sponsored by Chelan County Natural Resources Department SRFB Request $106,247 Tributary Fund Request $19,000 Not a Project of Concern Not a Project of Concern

24 Skinney Creek Culvert Replacement Sponsored by Chelan County Natural Resources Department SRFB Request $64,592 Tributary Fund Request $11,399 Project of Concern

25

26 Upper Skinney Creek Culvert Upstream Downstream Corrugated metal Squash pipe W=1.90m H=1.40m Problem Outfall drop 32cm Culvert failure due to insufficient cover and excessive loads

27 Concern Will DOT provide matching funds? Why didn’t the DOT take care of this (culvert) when the previous work was done? Response This culvert is not the responsibility of the state. It is beneath a private road.

28 Concern Why didn’t the proponent apply for funds to remedy the downstream barrier first? Response Chelan County has applied to the Tributary Fund for funds to replace the downstream culvert Our intent is to replace the upper and lower Skinney Creek culverts concurrently

29 Concern Skinney Creek is an intermittent steam

30 Concern Skinney Creek appears to be a low priority intermittent stream. Why are passage efforts being focused here? Response Skinney Creek is a high priority stream because There is a known occurrence of Adult spawning Endangered summer steelhead There is a known occurrence of juvenile steelhead/rainbow rearing There is a known occurrence of spring Chinook rearing to the lower Skinney Creek barrier Bulltrout have recently been documented spawning in the parent creek, Chiwaukum, and there is potential for Bulltrout rearing or high flow refugia here. Dept. of Transportation has made a substantial effort to replace 3 barrier culverts upstream and it is the counties responsibility to replace the downstream culverts In the Upper Columbia Salmon Recovery Plan under “Short term Restoration Actions” it states “Increase connectivity along Skinney Creek” In the Wenatchee Watershed Management Plan Habitat Schedule it states “address passage barriers at Skinney Creek near mouth “ as a high priority Within the more arid eastern Cascades, small systems like Skinney creek are important for providing critical high flow refuge areas, predator escape cover, and summer rearing and overwintering habitat

31 Questions?

32 Beebe Springs Restoration Project Sponsored by Lake Chelan Sportsmen’s Association Project of Concern

33 Mill Creek Culvert Replacement Sponsored by Chelan County Natural Resources Total Project Costs $100,478 Total Request from the Tributary Fund $17,731 Not a Project of Concern

34 Site 11 Sponsored by Chelan County Natural Resources Department SRFB Request $92,659 Sponsored by Chelan County Natural Resources Department SRFB Request $92,659 Tributary Fund Request $16,351 Project of Concern

35

36 Concern This backwater channel may have low fish utilization Response This project will address the lack of refuge in the Lower Wenatchee River

37 Concern What is the possibility that the structure resulting from this design would persist and not fill back in? Response Expect minor sediment accumulation Backchannel will be constructed at a slight grade to promote scour of a thalweg

38 Concern The proponent should also consider a side channel project at this site rather than a backwater alcove Response Study will examine a flow through side channel

39 Concern These kinds of projects should be short- term fixes while long-term restoration progresses Response Chelan County watershed wide restoration approach

40 Questions?

41 Peshastin Creek CMZ Assessment Sponsored by Chelan County Natural Resources Department SRFB Request $106,460 Tributary Fund Request $18,787 Not a Project of Concern

42 General Discussion and Closing Comments
