Comments

although several large undercuts were noted, as well as frequent debris jams, these were clearly related to Irene impacts and we were reluctant to tally any as refugia at this stage; likely that several of them will qualify better with channel evolution and stabilization. Given 2.8 pct slope (GIS calculation) its conceivable that reference should be Step-pool, but riffles also appeared relatively well-formed; large woody debris is playing an important role in sediment storage and step formation.
