Water quality
Clean water means more fish. We care about the water we fish, so here's where sewage is going into it near you, straight from the water companies' monitors.
Why it matters to anglers
- Sewage feeds algae that use up the oxygen fish need to breathe. Low oxygen drives fish away and can kill them.
- Polluted estuaries are where many sea fish grow up. Bass, flounder and mullet use them as nurseries, and fewer young fish now means fewer to catch later.
- Shellfish beds close, and bait dug from polluted mud can carry bacteria. Wash your hands before you eat, and cover cuts.
- Water quality is usually worst for a day or two after heavy rain, when overflows are most likely to run.
Where this comes from
Storm overflow data comes from the water companies' monitors (in England, through the National Storm Overflow Hub) and is usually within an hour. A monitor can show a discharge that didn't happen, or miss one, and some are offline. Overflows cover England and Scotland; bathing waters cover England only for now.
