Comments: Location: Oil Well Road to Tribal Council Road. Stream: The stream formed a pond fro ~40' upstream and then went subterranean w/ overgrown vegetation. No stream flow measurements were taken--the stream was too shallow and it merged with another stream 30' downstream of the pipe. Culvert: Two overflow pipes were dry, overgrown with vegetation and were well above local stream surface in area. The left had a 1' hole on top with road surface gravel inside and the right was squashed. The functional pipe was perched. Pipe condition=3 (functional, with rust and abrasion showing). Not embedded.
