Comments:
Alluvial fans above and below waterfall, at least 7 different major flood chutes several of which may have been the active channel over time. Valley width increases toward base of slope. Berming/straightening at base likely to increase erosive power on opposite bank of Mainstem across from culvert at base of reach; may eventually trigger mass failure under Rte. 110. Berming/straightening also increases the chance of the culvert plugging with debris.
