Site Comments: None

Survey Date: Jun 09, 2017

Survey SEA17-CEM01

Observers: Elizabeth Flory, Mark Eisenman

Overall Fish Passage Rating: Gray

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Hydraulic flows exceeded capacity
  2. Culvert gradient gray
  3. Constriction ratio gray
  4. Outfall height gray
  5. Structural Problem
  6. Mechanical damage or joints parting

Comments: Channel split 10ft upstream. Took downstream widths as upstream braided. Downstream widths taken close together in section where braids joined but before another tributary comes in. Lots of large woody debris over creek.
