Comments: Location: Oil Well Road to Tribal Council Road. Stream: Stream lies in an open marsh that it drains. Substrate is mixed rocks. Due to ponding upstream of inlet, flow measurements were done downstream of outlet; rocks were problematic. Washout gravel formed a gravel bar 6ft in diameter downstream from the pipe. Bank undercut ranged from 0.5-2.5'. Culvert: Upstream ponding and erosion resulted in 1" stream depth in pipe. Outlet is supported by logs (1' diam.), extends 6' from roadside and is perched. Pipe condition=4-5. Not embedded.
