Description
The project restored fish passage access to ~1.5mi of habitat for coho salmon and ~3mi for steelhead trout in the Scott Bar Mill Creek watershed. The project improved stream channel geomorphology and removed culverted and ford crossings (complete passage barriers). Additionally, the Mill Creek channel was realigned to reduce the channel slope from 12% to 6% starting at the confluence with the Scott River and working upstream. This was completed by excavating a new 200ft channel consisting of large rock, logs with root wads, and engineered streambed material. Placement of 10 channel structures provided habitat complexity to 0.1 acre of streambed. The new channel transitions into the existing channel profile. A concrete ford crossing was demolished and replaced with a 70ft prefabricated steel bridge supported on concrete abutments capable of conveying 100yr flow event.
All FY18 and FY19 PCSRF funds were spent within the appropriate award periods.
Project Benefit
Expected benefits include volitional coho access to 3 miles of intrinsic spawning and rearing potential restricted by 2 passage barriers at the mouth. Creating fish-passage will provide seasonal thermal refuge for migrating and rearing coho juveniles, as well as shelter and velocity breaks during periods of high water within the mainstem Scott River. These benefits will increase coho productivity in the Mill Creek watershed and further enhance the Scott River population.
