Comments:
Segment is adjacent to ponds. Segment has been altered through windrowing up on banks preventing floodplain access. Berm on left bank. 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. Diversion is bringing water from the channel to the pond. 2015 ASSESSMENT NOTES: In 2015, impacts observed during the Phase 2 assessment were very similar to those recorded in 2011. The water withdrawal and associated berms and windrowing were still the primary stressor to this segment. Additional bank erosion was observed in the windrowed sections in 2015, which suggests that the river may be beginning to widen. The headcut that was present in 2011 was not observed in 2015. The cross section was nearly identical in channel dimensions between 2011 and 2015. Similarly to 2011, geomorphic condition was fair in 2015 and habitat condition was also fair.
