Vegetative protection or natural rock 

prominent (60-80%) AND/OR 

Depositional features contribute to 

stability. The bankfull and low flow

Slightly incised, few areas of active 

erosion or unprotected banks. Majority 

of banks are stable (60-80%). 

Vegetative protection or natural rock 

prominent (60-80%) AND/OR 

Depositional features contribute to 

stability. The bankfull and low flow

has access to bankfull benches, or 

newly developed floodplains along
