Legal Description: F009N016E05
Region: Interior
Road Name: Steese Highway

Datum: WGS84
Quad Name / ITM: Circle C-1
AWC Stream #:
Stream Name: Jumpoff Creek

Elevation:

Site Comments: None

Survey Date: Jul 27, 2010

Survey EDS10-STS34

Observers: Ben Histand, Justin Leon

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Road bank erosion
  2. Culvert gradient red

Comments: There are pieces of culvert scattered upstream of this culvert. Downstream of this culvert the creek bed can be seen, but it is almost completely dry. No stream widths were taken here because the channel is in flux and there would be no consistent widths.
