Barrier Type
|
full obstruction to juvenile RB velocity barrier/ hanging culvert barrier to adults under high flow |
Prescription
|
install larger diameter open bottom arch culvert in stream channel a bridge should be considered due to the high water volume, channel width and velocity. |

Comments:
-moderate spawning potential downstream
-the road surface appears to have been eroded by a high water event which overtopped the culverts.
