Site Comments: DOT#19+080

Survey Date: Aug 07, 2010

Survey EDS10-DAL04

Observers: Mark Eisenman, Justin Leon

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Inlet perch
  2. Constriction ratio red
  3. Mechanical damage or joints parting
  4. Outfall height red
  5. Damage associated with ice problems
  6. Culvert gradient gray

Comments: 3 pipes. C1 has no flow and may be acting as an overflow pipe. C2 takes most of the flow. It has an inlet perch and a max gradient at 14 feet from the inlet. C3 is severely damaged at the inlet and no water passes through it there. It does appear to have a small amount of flow, but it must be coming up into the pipe from underneath it. During the survey a fish was seen at the inlet of C3.

Comments: Culvert 2 takes most of the flow and was used as the sole factor in constriction ratio as C1 is set as overflow and C3 is severly damaged at the inlet an no water passes though it.
