Survey EDS10-STS24

Observers: Ben Histand, Justin Leon

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Inlet perch
  2. Outfall height red
  3. Culvert gradient red
  4. Constriction ratio red

Comments: There is an inlet perch caused by boulders in front of it. This stream appears to be semi-dammed upstream for water trucks. Water is piling up at both sides of the inlet. There is a large outlet pool.
