Site Comments: DOT# 868+30 Milepost 13.

Survey Date: Jun 28, 2010

Survey EDS10-ELH15

Observers: Mark Eisenman, Justin Leon

Overall Fish Passage Rating: Green

Tidal: No
Backwatered: Yes

Step Pools: No
Construction Year:


Site Observations:

  1. Culvert gradient red
  2. Culvert gradient gray

Comments: There are 2 pipes here. C1 is submerged and C2 is as well. The water is murky, it was difficult to find the inlet and outlet and it could not be confirmed if there was an apron or not. C1 appears to be fully clogged at the outlet. There is a deep pool at the outlet of C1. No constriction ratio was calculated because this culvert connects a pond to another pond. Also, any other measurements or calculations that are not present are because the pipe was fully submerged and clogged with debris.
