Survey Date: Jun 24, 2010

Survey EDS10-ELH11

Observers: Mark Eisenman, Justin Leon

Overall Fish Passage Rating: Gray

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Structural Problem
  2. Mechanical damage or joints parting
  3. Damage associated with ice problems

Comments: The inlet of this pipe is bent in and up. This looks like prior ice damage. This is backing up water before the pipe. The max outlet pool depth = 1.10ft at 3ft from the outlet. The stream grade seems to be a good habitat. There are not too many drop offs. The length was obtained from the DOT placard. No longitudinal profile was done at this site because it was too steep and there was too much brush. No minnow traps set.
