The Elochoman Hatchery has been shut down since early 2009. At that time all infrastructure was left in place. This included the water supply system on Clear Creek that was used for incubation. The hatchery grounds have been severely pilfered and degraded and currently represent a hazard to fish and wildlife. This project removed the intake system which included the removal of a full spanning concrete dam, removal of 275 feet of an access road and supply pipe that ran to the intake, bank restoration/vegetation to match existing upstream and downstream conditions, installing large woody debris (bank structures and in-channel placement), and removing an old derelict timber bridge spanning Clear Creek at the downstream end of channel work.

The intake system included a full spanning concrete dam with a three step concrete weir-pool fishway. The wooden stop logs were no longer in place and the fishway had not been operational for some time. The intake structure was approximately 6 above the existing channel grade and was a full barrier to fish passage. The screening material at this intake were not compliant with NMFS/WDFW standards. The water right for this intake had been lost as a result of not using it for the past 10 years. The access road to the intake structure ran adjacent to Clear Creek, tightly confining the floodplain. The road fill material was be pulled back and removed from the site to provide 3-6 foot floodplain bench and a more gradual (2:1 or shallower) bank slope. Additional wood will was added to the channel in 8 locations, including 11 logs with root wads and 10 additional logs without root wads. Approximately 90 cubic yards of streambed material was added to the channel where the dam was removed and where the road was pulled back. The area was planted with 450 potted plants and 1,500 live stakes. A total of 340 linear feet of channel and 420 feet of stream bank were restored/revegetated. This project also included the removal of three pipeline valves located on a downstream landowners land.

Project Benefit    

Remove current intake structure on Clear Creek which blocks fish passage of wild winter steelhead, listed chum and coho salmon. Adequate habitat exists above blockage that could be utilized more fully now there is full passage. Rearing and spawning habitat increased with the addition of streambed material and LWD.
