White foam is collecting along the stream edge near the footbridge. It stays in patches as the water moves.
22 Sept, 03:40 amOpened an investigation. A photograph alone cannot explain the cause.
No visible foam from the upstream public path. The water surface looks clear here.
22 Sept, 03:58 amAdded a comparison: the visible condition may be local to this reach.
Similar foam patches are visible downstream from the bridge, seen from the public walkway.
22 Sept, 04:12 amAn independent observation supports the original report.
Returned to the same public viewpoint after one hour. Foam is still collecting along the edge.
22 Sept, 04:40 amEstablished persistence over time; this is not a second independent witness.
An unusual strong smell was noticeable from the path. I moved away without approaching the water.
22 Sept, 04:48 amRaised a safety flag. Nearby verification missions were paused.

The original photograph was shared again. It records the same observation, not new evidence.
22 Sept, 04:55 amLinked as a potential duplicate. It adds no independent support.
The clear upstream observation limits the apparent extent. It does not disprove the downstream reports.
Do not treat repeated or duplicate observations as independent support. Resolve uncertainty explicitly in the review.
