Survey Date: Jul 03, 2006

Survey SEW05-COR13

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. Constriction ratio red
  2. Sediment accumulation
  3. Road bank erosion

Comments: Flow splits and passes through two pipes, both surveyed. Two additional overflow pipes between the main pipes were not surveyed and were dry at time of survey. Flow remains in two separate channels until confluence with East Fork Solomon River. Snow during survey.
