Site Comments: Mile 0.0. Located adjacent to driveway. Concrete sidewalk at site. Can see culvert to Snake River d/s of site

Survey Date: Oct 12, 2005

Survey SEW05-TR21

Project Supervisor: Dave Ryland,
Observers: Dave Ryland, Jason Cheney

Overall Fish Passage Rating: Gray

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Other, including vibrations, cavitation, etc.
  2. Constriction ratio red

Comments: u/s channel- U-shaped, deep and incised, high water during survey, sand/silt/small gravel substrate. Both inlet and outlet contain deep accumulation of rocks, otherwise channel is deep both in adjacent channel reaches and inside pipe. Outlet profiled, see elevations. Water may be too shallow at inlet and outlet at low water to allow fish passage.
