Comments:
Though valley is narrowed by human activities, including historic dam mid-reach, overall the reach appears semi-confined naturally. Pinch points (confined) are at bedrock grade controls and stream is overwidened in these areas, bedrock outcrops are common along LB. Ice scour and tree damage common. Geo. Springston research indicates northern limits of glacial Lake Hitchcock 'finger' likely in DS portions of this reach. Possible that plane bed stream type is a departure from reference riffle-pool, but field observations, slope (1.1 pct by GIS) and natural confinement lend to coarse plane bed as reference.
