Any river activity poses a greater risk when there are:

River flows can increase even during the summer months. Never assume that sunny weather means the conditions are not hazardous.

We (the Environment Agency may display warning boards at locks to inform river users of the conditions. Read the explanations of what these mean for you. Do not take risks and never underestimate the power of the river.

A red sign with white text reading 'Strong stream advice. Do not attempt to navigate. Locks discharging floodwater'.

These signs are displayed when river flows are above normal levels, making conditions unsafe for navigation. Water currents may be too fast for safe manoeuvring, and headroom may be restricted at some locations.

During these periods, some locks are ‘reversed’ to discharge floodwater. Reversed locks are closed to navigation, and red LED ‘X’ lights are activated at the lock. These warn boaters to keep well clear of the lock. Some marinas and boat clubs may also display red flags.

We strongly recommend that you do not attempt to navigate during these periods.
