Second Week of August
Through traffic on lower North Bank Road in the vicinity of Fahys Creek was closed from August 11-13 as raising of the road grade accelerated in this area. A continuous string of truckers working for Tidewater Contractors delivered fill material from the Dew Valley Quarry. Filling and compacting has been nonstop and the roadbed near Fahys Creek is rising rapidly. In addition, the future pedestrian underpass near the Refuge Office was installed under North Bank Lane. The pedestrian underpass is comprised of an 8’ diameter culvert and is located off of the Refuge overlook parking lot. The large structural plate culvert for Fahys Creek is being fabricated in Pennsylvania. Originally scheduled for arrival on August 16th production was delayed and the culvert is now scheduled to arrive on August 23rd. Although filling and compacting of North Bank Lane will continue this week, one lane through traffic with short delays will be allowed. When the Fahys Creek culvert arrives the road will be closed once again from August 23-31 as the flow in Fahys Creek is diverted around the construction site and the large culvert is installed.

By the end of last week Knife River Corporation had completed filling all the major agricultural ditches with spoils from the new tidal channels, and the channel for Fahys Creek was completed except for the upper connection to the existing channel. Fahys Creek channel is the largest channel to be constructed, ranging from 9 to 22 feet wide, and up to 5 feet deep. By the end of next week, we expect to begin shifting Fahys flow into its new channel. Knife River employees have done a great job in constructing the sinuous tidal and creek channels. We are in the process of tallying the totals, but we rescued and relocated thousands of amphibians (mostly rough-skinned newts) out of the old ditches as they were being filled, representing an astounding population of this 6-inch salamander.

Last weekend we installed an automated time-lapse camera on a 30-foot pole to photograph the construction of the lower Fahys Creek channel and filling of ditches. The camera captured dramatic footage of Knife River crews creating the new Fahys Creek channel. The camera will continue to record activities for another 2 weeks and will ultimately be an important segment of a documentary video about the restoration project.

While lots of activity was going on “behind the scenes� field crews for Doyon Government Service and Michels Directional Crossings were idled all week as the east bore continued to be redesigned. 10� diameter steel casing is being shipped to the project site from the mid-west. Work on the east bore and the undergrounding of the electrical transmission line should be reinitiated next week.
