Questions about Blyth (N)

Which outlets are linked to Blyth (N)?
The source links 21 outlet records to waterbody GB510302203200. The link comes from the annual return; it does not model where a discharge travelled.
How many spills were recorded for Blyth (N)?
21 records report 475 spills in 2025 and 2,966 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 Blyth (N)?

Which outlets on Blyth (N) are linked to a live feed?
20 of the 21 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 Blyth (N)?
2 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 Blyth (N) is safe?
