Questions about Ely Ouse (South Level)
- Which outlets are linked to Ely Ouse (South Level)?

- 23 records report 153 spills in 2025 and 744 recorded hours. All listed records have a usable count. Outlets can discharge at the same time, so the hours are not the time the whole water was affected.

- Which outlets on Ely Ouse (South Level) are linked to a live feed?

- How complete is the monitoring for Ely Ouse (South Level)?
- 1 of the listed records have monitor operation below 90% for 2025. Events can be missed when a monitor is not working, so low counts from those outlets may understate activity.
