The End of August
Marsh restoration work continued at a fast pace last week by Ducks Unlimited (Knife River Corporation). Except for a 50’ section at North Bank Lane, Fahys Creek was diverted from the old straight-lined agricultural ditch that served as the creek for nearly 100 years to the newly constructed meandering stream channel. Once fish were relocated and flows diverted from the old Fahys Creek channel the straight-lined ditch was filled and obliterated. Incredibly, several days after the water was diverted into the new creek sea run cutthroat trout, with sea lice attached indicating they had just moved in from the ocean, were already using the new meandering channel. All major agricultural drainage ditches have now been filled and approximately 98% of the new tidal channels have been constructed. Knife River began to place large woody debris in new tidal channels to serve as habitat for fish and invertebrates and to provide habitat complexity. The design and location of the large woody debris was done by Stan Van de Wetering of the Confederated Tribes of the Siletz Indians. Randy Van Hoy of Ducks Unlimited did the engineering of the large wood placement. On the last two days of the month work began on restoring the historic Fahys Creek forested wetland (abandoned cranberry bogs) north of North Bank Lane.

Federal Highways Administration (Tidewater Contractors) began replacement of the 54� Fahys Creek culvert with a 15’ by 10’ plated culvert. The job necessitated closing North Bank Lane to all traffic as a massive hole was dug to place the culvert. The job was complicated by the fact that an artesian spring emerged in the bottom of the construction site with a flow rate of ~40gpm. Over 2,000 cubic yards of earth was removed from the site for culvert installation, which was completed today. Bank stabilization and erosion control (Hydro seeding and wattles) along Redd and Fahy creeks road grade raise shoulders was also completed.

On August 25th Doyon Project Services (Michels Direction Crossings) completed casing the entire second bore under the Coquille River with 10� diameter and ½� sidewall steel casing. The 38’ lengths of casing were butt-welded and pulled through the bore. That evening they began to pull the PVC conduit back through the cased bore and completed the job on Thursday. The drilling equipment departed the job site on Friday, but Doyon Project Service and Michels Power continue to work on the powerline undergrounding. The under river bored conduit has been fused to the floodplain trenched conduit and the remaining trench backfilled. The excavation for the south vaults is complete and the vaults will be set soon. Pulling of the electrical cables through the underground conduits should begin next week.

On August 24th the USFWS conducted an aerial photo flight over the project area to document the construction completed to date. Still photography and video was taken during the flight.
