Site Comments: None

Survey Date: Jul 05, 2010

Survey EDS10-LIV01

Observers: Mark Eisenman, Justin Leon

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Compound gradient in pipe
  2. Constriction ratio red
  3. Culvert gradient red
  4. Structural Problem
  5. Mechanical damage or joints parting
  6. Outfall height red

Comments: The inlet of this culvert is bent up severely and no water passes through it. The end section of the inlet has been ripped away. The pipe is separating, allowing water to pass through the separated spots as well as underneath the pipe itself. The outlet of this pipe is releasing water too fast. There is a compound gradient within the pipe.
