Comments: Creek is a tributary to Switzer Creek and the confluence is only about 20 to 30 feet downstream of crossing. Adult Coho seen downstream in Switzer Cr near confluence. Upstream culvert inlets have been covered by slash. Upstream creek runs into a lot of old slash and stumps. Unclear if all this woody debris is creating an instream barrier. All culverts appear to be perched over 4 inches, but site would need to be surveyed to verify. Site does appear to be a barrier to fish passage.
