Survey EDS10-STS23

Observers: Ben Histand, Justin Leon

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Outfall height red
  2. Culvert gradient red

Comments: There is a pond upstream with an unknown liquid resting at the bottom. The outlet is torn on the left side if you are looking upstream. No minnow traps were set out because the water is too shallow other than the pond upstream.
