Comments: Location: Oilwell Rd. Stream: Stream lies at the base of a steep hill. Extensive ponding: 3' deep, 50' wide, and extends beyond 75' from the inlet. Measurements from the inlet and outlet were problematic due to logs. Gravel from washout is in large pile downstream of outlet. Dense alder and willow growth along stream. Culvert: It appears as if the road had washed out partially and was rebuilt by laying logs over the culvert and then adding gravel. The pipe is heavily embedded. Benchmark is located on tree stump located on the right bank near the outlet (see data form for more info.). Pipe condition=3 (should be replaced).
