Site Comments: On 29 mile pullout. Remains of an old bridge upstream from this culvert.

Survey Date: Jun 24, 2010

Survey EDS10-ELH08

Observers: Mark Eisenman, Justin Leon

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Outfall height red
  2. Mechanical damage or joints parting
  3. Structural Problem
  4. Constriction ratio red

Comments: This pipe is rusted throughout. No minnow traps were set here because the water level was too low. There are the remains of an old bridge upstream from this culvert. The pipe gradient and the length could not be calculated because of ice blockage and a bend in the pipe but the pipe is red by the outfall height alone. The constriction ratio should be disregarded - there are big pools throughout and no real runs.
