Comments:
Lower 800 feet of this segment is likely a straightened "F" stream type, but we did not have access to this area of the river. There was a short area with windrowing at the downstream end of the segment. Segment extremely flood affected (May 2011). Braided even under lower flows. Although Brook Road is not technically a Phase 2 valley wall (state numbered highway), we feel that in this system it is acting as a confining feature (Phase 2 valley wall). Human-caused change in valley width results in a change in valley type from Broad to Narrow, changing confinement ratio from 8.1 to 5.8.
