No wind

Flow initially slow downstream but then started going back upstream with translucent 'skeins' across water surface visible. Flow about 5 min. later stopped then started to move slowly downstream for very short period then returned to upstream (possibly coincided with low tide)

Main river channel was flowing extremely fast

Large amount of dead veg. in flow.

Surface covered by large 'slick' moving upstream & downstream under the bridge as flow changed

During monitoring the flow was up stream from 0.10m to 2.00m. It then changed & went downstream at 2.50m  The change in movement was throughout the water column not dependent on depth.
