Prescription

 

 

 

replace with larger culvert imbedded in channel at upstream location. Channel presently runs alongside the road.

Form A - Fish Passage - Culvert Inspection - Side 2

 

Comments:

poor culvert placement - creek runs alongside road

channel width of the old channel is < new channel. Run off from sources down to the 16 km mark appears to have increased flows in the channel beyond what would naturally be present
