Alerts
Get an email when something fires
Subscribe to Truth Engine flags for a stretch of water you care about — your local river, the canal you fish, the overflow upstream from where you swim. We'll email when it fires, with the evidence and a one-click route to take action.
Free for citizens. Bulk subscriptions for angling clubs, paddle clubs, hire centres and parliamentary briefings — email data@rivertruth.uk.
How alerts work
The Truth Engine runs every hour
After each run, we scan your subscriptions and email you for any newly-raised flag that matches your scope and severity threshold.
We dedupe within 6 hours
If the same overflow keeps flapping, you get one email — not ten. Different overflows on the same scope still each get their own email.
One-click unsubscribe
Every alert email contains a signed unsubscribe link that deletes the subscription instantly — no login required.
We never share your email
Used only to send the alerts you ask for. No marketing, no third-party sharing. Read the methodology on the About page.
