Questions about Queen Street Bridge/CSO
- Who operates Queen Street Bridge/CSO?
- Yorkshire Water is the operator named in the annual record. The permit reference is 27/24/0453.
- Where does Queen Street Bridge/CSO discharge?
- The source names River Ouse as the receiving water. This does not show how far a discharge travelled.
- How many times did Queen Street Bridge/CSO spill in 2025?
- The 2025 return records 23 counted spill events and 20.8 hours of recorded discharge. Spills are counted with the 12/24-hour method, so this is not a count of every start signal.
- Can I trust the 2025 figures for this outlet?
- The monitor worked for 84.1% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
- Is Queen Street Bridge/CSO discharging right now?
- This record is linked to a company live feed. The panel above shows the latest report we hold, with its date. That report can be old, and the monitor can be offline, so check the date before relying on it. A report that no discharge is taking place is not a water-quality result.
- 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.
- What kind of outlet is Queen Street Bridge/CSO?
- The annual return lists the asset type as “SO on sewer network”, which means storm overflow on the sewer network. The return places this overflow on the sewer network.
- How does Queen Street Bridge/CSO compare with other overflows?
- Queen Street Bridge/CSO recorded 23 spills in 2025. That is more than 67% of the 14,239 overflows in England with a reported figure, and ranks 4,513th nationally. Among Yorkshire Water overflows it ranks 864th of 2,176; the median Yorkshire Water overflow recorded 16 spills. On the Ouse from River Nidd to Stillingfleet Beck waterbody it ranks 19th of 41. Ranks compare counted spill events only. They do not compare volume or harm.
- Does zero spills mean the water was safe?
- No. A zero means the annual return recorded zero counted spill events for this outlet and year. It is not a water-quality test, and pollution can come from other sources.
