Comments:
Historic incision causing widening, aggradation, and planform adjustments. Beavers and lack of forested buffer exacerbating processes. Cross section resurveyed in 2014 by Bear Creek Environmental. Surveyed cross section 45 feet upstream of 2009 location due to bank slump at 2009 location (indicating widening). Cross sectional area in 2014 was lower than in 2009 but was consistent with upstream areas. A higher width to depth ratio (14.9) indicates that perhaps the channel is a C in some areas.
