- How many times did Bristol Portway Near Plimsoll Bridge (Pumped) spill in 2025?

- How accurate is the map marker?
- The marker comes from the grid reference in the official annual return, which is accurate to about 1 metres. It shows the recorded outlet position, not the extent of any discharge.
