Survey SEA17-NPW19

Observers: Elizabeth Flory, Kelly Petty

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Outfall height red
  2. Culvert gradient red
  3. Constriction ratio gray

Comments: Small pool just above inlet. Lots of old logging slash covers first 100ft of stream upstream, some 3ft diameter logs. Some large woody debris steps, fairly low gradient. Slash is covered in moss and forest debris. Shallow, not many pools. Outfall 6ft. Lots of spruce downstream. Too brushy for gradient survey.
