Questions about Middle Level

Which outlets are linked to Middle Level?
The source links 24 outlet records to waterbody GB205033000050. The link comes from the annual return; it does not model where a discharge travelled.
How many spills were recorded for Middle Level?
24 records report 357 spills in 2025 and 2,942 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.
Who is responsible for the outlets on Middle Level?
Anglian Water operates every listed outlet. Contact the operator or the official pollution service if you see a problem in the water.
Which outlets on Middle Level are linked to a live feed?
24 of the 24 records are matched to a monitor in a company live feed. A link does not mean the monitor is working now. Use the status filters above to see the latest report for each outlet, with its date. The rest show annual figures only.
How complete is the monitoring for Middle Level?
3 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.
Does this show if Middle Level is safe?
No. Event duration data does not measure bacteria, chemicals or current water quality. Use official local water-quality advice for that question.
