Strong Stream Advice

The Environment Agency issues Strong Stream Advice (SSA) to inform river users when river levels are increasing and when locks are being prepared to discharge flood water. Notice boards, flags and lights are displayed prominently on riverbanks to inform boaters of the status of the river and red flags are also raised at several boat clubs. Environment Agency currently issue SSA on the River Ancholme, River Nene and River Great Ouse (Bedford Ouse).
