  Score STD (7.5) Historic (7.5)
7.1 Channel Degradation 8 C to B No
7.2 Channel Aggradation 8 None No

7.5 Channel Evolution Model F  
  Channel Evolution Stage III  
7.6 Geomorphic Stream Condition Poor  
7.7 Stream Sensitivity Very High  
7.5 Channel Adjustment Processes Narrative  
  Extreme planform change with major widening and aggradation. Higher terrace on RB indicates historic incision while lower terrace likely indicates more recent incision. Stream is functioning in a diminished floodplain at lower elevation, and further incision could result in an F-type stream and higher instability.
