Survey MSB11-NKL01

Project Supervisor: Gillian O'Doherty, Alaska Department of Fish and Game — Anchorage, AK
Observers: Abraham Gioffre, Jim Latham

Overall Fish Passage Rating: Green

Tidal: No
Backwatered: No

Step Pools: Yes
Construction Year: 2008


Site Observations:

  1. Culvert gradient red
  2. Woody Debris
  3. Beaver Activity

Comments: Culvert connects a marsh land to a lake. The inlet is clogged with a beaver dam which is blocking nearly all water flow. The substrate/beaver dam at the inlet is too deep to measure. The dwst area is a very shallow ferrous flocculent muck substrate in a marsh area. No stream widths or measurements taken. **Updated site photos collected from 9/30/16 site visit from Sampling Unmapped Streams in the MSB project. Fish sampling information entered into AFFI *** Beaver dam has been removed since 2011 visit. Lots of coho and ninespine sticklebacks upstream.
