How to read it
Every spot page shows the same three readings, plus any flood warning in force. Together they tell you whether the river is likely to be carrying sewage, running high, or about to.

01
Storm overflows upstream
United Utilities, Thames Water and Yorkshire Water monitors report every overflow that is discharging. We trace every monitor upstream of a spot, tributaries included, and summarise the last 48 hours and 30 days.

River level and trend
Environment Agency gauges read the river every 15 minutes. The latest reading, the change over 3 hours and where it sits in the gauge's typical range. High and rising means fast, cold water.

Rainfall nearby
Totals from the nearest rain gauge over 6 hours, 24 hours and 3 days. Rain is what triggers overflows and lifts levels, so it is the earliest signal you get.

Flood alerts and warnings
When the Environment Agency has a flood alert or warning in force for a spot's stretch of river, the spot page shows it in their own words, with a link to the latest on GOV.UK.
