Comments: Location: Oilwell Road. Stream: Slow stream flow with moderate ponding upstream and significant gradient changes downstream. Substrate was very soft/silty at inlet and gravel at the outlet. Flow measurements done at 175' with very slow surface flow. Culvert: Three pipes were side by side at this site with only one as an overflow pipe. The center pipe was slightly squashed but functional. Pipe condition= 4-5. Not embedded.
