Legal Description: F006N004W13
Region: Interior
Road Name: Elliott Highway

Datum: WGS84
Quad Name / ITM: Livengood B-3
AWC Stream #:
Stream Name: Tatalina River tributary

Elevation:

Site Comments: DOT# 2528+96 and 2528+91

Survey Date: Jun 29, 2010

Survey EDS10-ELH18

Observers: Mark Eisenman, Justin Leon

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Culvert gradient red
  2. Woody Debris
  3. Inlet perch
  4. Sediment accumulation

Comments: This culvert has 2 pipes. C1 is almost completely clogged with woody debris. C2 has a big inlet perch and is also heavily clogged with woody debris. The length of these pipes could not be shot with a laser so DOT placard lengths were used.
