Comments:
Mostly narrow valley with occasional pinch points (as low as 70 ft), which are commonly bridge or culvert crossings, and alternating intermittent pockets of wider valley. Farm fields at base of reach situated on likely alluvial fan on one corner of northern extent of "First Branch arm" of glacial Lake Hitchcock, a kame terrace largely comprised of sands. Stream has historically incised deeply through these sands, is pinned to LVW and functions in diminished floodplain so was not segmented out. Hard turn to LB just US of farm is at a knoll that is an unusual feature forming an effective valley wall at this point in time (10 ft HAW, drops to 6-7 ft HAW shortly DS), may be composed of less erodible materials than the surrounding sands through which the stream has eroded historically. Stream diverges from VHD mapping (by 200 ft plus, toward the LVW) on US end of this fan, ~900-1000 ft US of the base of the reach - indicative of ability of debris jams and/or sediment plugs to shift stream from side to side in this valley, leaving evidence of old channels and/or flood chutes on opposite sides. Berm on right bank in midsection of reach is mostly remains of bark and tailings from former Meadowbrook Lumber yard pushed to one side and could potentially provide some floodplain access if cuffed out (not clear how restrictive these tailings are).
