Site Comments: Mile 64.4. On curve. Pull out to SE corner of x-ing. Confluence with Fox River 150' d/s

Survey Date: Jul 01, 2006

Survey SEW05-COR06

Project Supervisor: Dave Ryland,
Observers: Dave Ryland, Kyle Negri

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Mechanical damage or joints parting
  2. Culvert gradient red
  3. Constriction ratio gray

Comments: Pipe crushed at inlet and outlet so invert elevations approximate. Culvert may have been a pipe arch, estimate opening to be approx 3' x 5'. Both inlet and outlet are turned down.
