Site Comments: This culvert has a break in it. The break is a storm drain. Site runs under Steese Highway/Elliott Highway wiegh station and Elliott Highway.

Survey Date: Jun 10, 2010

Survey EDS10-ELH01

Observers: Mark Eisenman, Justin Leon

Overall Fish Passage Rating: Green

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Sediment accumulation

Comments: Pipe is at an intersection and runs underneath both roads with a bend in the middle. The inlet-end of the pipe above the bend is 153' and the outlet-end section is 108'. This culvert has a break in it for a storm drain. There is heavy sedimentation throughout the pipes. There is rip-rap present at the inlet and outlet. Both upstream and downstream are ditches so the constriction ratio might not be used.
