Survey CRWP17-Glen2

Observers: Kirsti Jurica, Hoots Witsoe

Overall Fish Passage Rating: Gray

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Constriction ratio gray
  2. Beaver Activity
  3. Culvert is poorly aligned

Comments: Culvert assessment performed and submitted by the Copper River Watershed Project. Majority of water flows through pipe 2. Inlet damage to pipe 2 due to poor alignment with upstream channel. Pipe 1 placed higher than Pipe 2 for flood control. Multiple channels upstream from culvert.
