Site Comments: DOT# 3073+88

Survey Date: Jun 29, 2010

Survey EDS10-ELH19

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. Culvert gradient red

Comments: The mitered piece at the outlet of this culvert is starting to separate. No stream widths were taken and no constriction ratio was calculated because this culvert connected a pond to a pond. An adult arctic grayling was seen going upstream through this culvert.
