Comments:
Three head cuts present. Braided system. Stream is cutting down through deposited features. Old logging practices have left debris that is holding back sediment and not stream is cutting through the deposits. It is recommened to determine the meander width ratio and the wavelength ratio to help assess the stability of the reach. This was not done as part of Phase 1. 2015 ASSESSMENT NOTES: In 2015, debris jams were more numerous and larger than those noted in 2011. Multiple flood chutes have formed as a result of these jams. No headcuts were observed within the segment during the second assessment. Bank erosion was more abundant in 2015 than in 2011. Geomorphic condition was again fair in 2015, while habitat condition came out as good.
