  Comments significant dozing post-Irene makes it difficult to know if overall reach reference is plane-bed (slope of ~2.7 pct and Narrow valley for much longer segment B are a fit) or whether this is solely a result of channelization and dredging. Several constructed weirs were placed post-Irene to arrest headcutting resulting from dozing, which account for subdominant step-pool features.
