Part I — The scene

Every monitored outfall on the Exe, in one view.

339 storm overflows feed the Exe and its tributaries. Colour is state, not decoration — coral means discharging with no rainfall recorded.

Part II — The evidence

When the discharge line rises and the rain line doesn't.

We cross every discharge against the nearest rainfall gauge. No rain, still discharging — flagged automatically.

Nothing is currently discharging with no rainfall recorded at its nearest gauge.

Part III — The record

Every spill day for one outfall, the way a chart should show it.

MELDON RD · CSO · CHAGFORD · each square is a day. Deeper coral means longer discharge; the reddest days had no rain recorded.

Part IV — The named

The outfalls discharging longest, ranked.

By total discharge hours this year. The coral figure is the share with no rainfall recorded at the nearest gauge.
