Comments: Location: Oilwell to Brody Rd. Stream: Ponding present a short distance upstream; then stream forms narrow channel and is overgrown with willows. Bank undercut was 6-24". Substrate is gravel downstream and soft silt upstream until channel forms and is then gravel. Culvert: Outlet is squashed and rolled over below water surface; has a small hole on top. The inlet has rust all the way around with a 3" hole 10" from the end. Pipe condition=3. Not embedded.
