Survey KEN17-KSH02

Observers: Maggie Schaffer, Elise Idle

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Constriction ratio gray
  2. Culvert gradient red
  3. Compound gradient in pipe

Comments: Culvert information and assessment data collected and submitted by USFWS. Stream splits into 4 channels downstream at about 30 feet from outlet. Lots of fish. Looks like upstream culvert on old road grade has been removed, but the remnants of the old culvert are still in the creek. Elevations erroneous could not be used to rate.
