Overall Fish Passage Rating:
Construction Year: 2012
- None of this type
Comments: Replaced with a stream simulation design in October of 2012 and bioengineering work on the channel was completed in June of 2013.
|ID: 1||Structure Type: Circular pipe (Corrugated steel)||Fish Passage Rating:|
Comments: Downstream constructed channel shows signs of head cutting . Coir logs have been undercut and some look that they might fall into creekwith more erosion. Upstream water surface flat and held by large boulders at inlet. Looks like some of the substrate inside the culvert has been washed out.
No stream width data available.
