Site Observations:

  1. Culvert gradient gray

Comments: Near road #2360. Nice habitat upstream and downstream, stream splits 250ft upstream. Confluence with Log Jam Creek 100ft downstream. No barriers. Large woody debris and pools. Some bedrock control. Shallow water depth though barrel of culvert, looks like channel has moved to sides of culvert.
