Comments: Location: Oil Well Road to 1200 Rd. Stream: Channel is braided upstream of pipe and narrows to one channel at 125'. The streambanks are very vegetated. The substrate is mixed rock sizes. Some vegetation growing in the pipe. Bank undercut ranged from 4"-10". Rocks in the channel interfered with stream flow measurements; taken at 125ft upstream. Culvert: Pipe condition=5 (good) The pipe had minor dents on the edges and rust all across the exterior. Not embedded.
