Comments:
Downstream end of Dickerman Hill Rd. rip-rapped heavily previous to Irene (2009); bridge area likely "cleaned out" at that time. Base of reach at confluence with First Branch Mainstem was windrowed post Irene (2011). Though these alterations may contribute to reduced sinuosity, it appears that slope and confinement also contribute to reduced sinuosity; have thus used +/-2 w/d ratio 'fudge factor' to class as C-type stream (current w/d of 11.4 is within range of E-type stream). Segment is on a likely glacial alluvial fan, though current valley is more entrenched; believe degree of entrenchment is more post-glacial than historical.
