First Stage of Outer Dike Removal Underway
Dike removal was the order of the week and is greatly changing the view of the landscape along the Coquille River. Contractor Knife River kept busy with two backhoes removing the outer dike and up to five 6-wheel dump trucks moving the spoils to fortify the east and west levees, which will protect our neighbors from tidal flooding. By the end of the week, only the southwest section of the outer dike remained to be lowered to the staging elevation. There is a much different feel to the area now with most of the dike removed. The high tide is only a couple feet away from spilling over top into the former pastures. On Friday, we took advantage of the low tide in late morning to install a temporary tidegate in the west dike. This allows us to shift the location of the Fahys Creek outlet, while Knife River begins to decommission and remove the old tidegate and back fill the existing lower artificial channel. Once the stream begins to flow through this new tidegate, it will mark the first time in over hundred years that Fahys Creek will return to the historical mouth location. Assuming we can continue at the current rate of progress, we anticipate the final tidegate and dike removal to occur ahead of schedule, during the week of August 15th. On August 3rd officials from NOAA-Fisheries toured the project site, followed the next day by the Natural Resource Trustees of the M/V New Carissa oil spill.
Tidewater Contractors spent the week burying more utility conduit and installing vaults along North Bank Lane. They are also making some progress on constructing the new Refuge office driveway.
