The official waterbody record is a source lookup; its classification is not imported here.
Questions about Middle Brook
- Which outlets are linked to Middle Brook?
- The source links 46 outlet records to waterbody GB112069064540. The link comes from the annual return; it does not model where a discharge travelled.
- How many spills were recorded for Middle Brook?
- 46 records report 1,081 spills in 2025 and 2,577 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 Brook?
- United Utilities operates every listed outlet. Contact the operator or the official pollution service if you see a problem in the water.
- Which outlets on Middle Brook are linked to a live feed?
- 45 of the 46 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 Brook?
- 6 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 Brook is safe?
- No. Event duration data does not measure bacteria, chemicals or current water quality. Use official local water-quality advice for that question.
