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
