7.5 Channel Adjustment Processes Narrative  
  The reach was incised and overwidened. The incision is likely due to historic straightening and encroachment along Route 112. Moderate bank scour and bankfull widths typically greater than the predicted curve width indicate that the reach may be widening. Further incision is also unlikely due to grade control and large substrate. We assessed the reach as early stage III with limited potential for further widening or planform adjustment due to the road encroachment.
