Site Comments: On the campground road. Site is downstream from STS16.

Survey Date: Jul 22, 2010

Survey EDS10-STS17

Observers: Ben Histand, Justin Leon

Overall Fish Passage Rating: Gray

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Mechanical damage or joints parting
  2. Structural Problem
  3. Constriction ratio gray

Comments: Water piles up to the left of the inlet if you're looking downstream. Water pours into the culvert after this. There is a 5 foot mitered section at the outlet and a 5 foot mitered section at the inlet. The outlet is bent up. Water surface measurements were used to calculate the gradient through the pipe.
