Dist from Clackamas R.: 12.8 miles
Upstream fish-bearing length: 1.1 miles

Comments: Natural fish barrier below. Could probably make this a passable culvert by backwatering with some weirs. Scouring on outlet end. Solution – Because of moderate length and moderate jump and slope this would probably not provide adult fish passage. Round culvert, embedded 45 ft long, placed at 3.5% grade. County estimate based on open box culvert.
