What the warnings mean

Any river activity poses a greater risk when there are strong currents, high river levels or cold weather conditions. River flows can increase even during the summer months. Never assume that sunny weather means the conditions are not hazardous.

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.

Strong stream warning

A red sign with white text reading 'Caution: Strong stream'.

Strong stream warning board

When these red boards are displayed, the Environment Agency advises users of all boats not to navigate. The strong flows make it difficult and dangerous.

People in hire boats arriving at a lock where these boards are displayed should stop immediately. Contact your hire boat operator to ask for instructions.

Stream increasing warning

A yellow sign with black text reading 'Caution: Stream increasing'.

Stream increasing warning board

When these yellow boards are displayed, the Environment Agency advises:

  • users of all unpowered boats not to navigate
  • users of powered boats to find a safe mooring

River flows are likely to strengthen, and strong stream boards could be displayed very soon and without further warning.

Stream decreasing warning

A yellow sign with black text reading 'Caution: Stream decreasing'.

Stream decreasing warning board

When these yellow boards are displayed, the Environment Agency advises:

  • users of all unpowered boats not to navigate
  • users of powered boats to navigate with caution

Using navigation marks

When travelling upstream, keep red navigation buoys to your left and green navigation buoys to your right.

When travelling downstream, keep red buoys to your right and green buoys to your left.

You may pass single yellow marker buoys on either side.

In all cases, keep well clear of navigation buoys. Be aware of possible shoals on the inside of river bends.

Dealing with changing river conditions

If you find yourself in conditions where the Environment Agency advises you to stop navigating, please take the advice and stop. Even the most experienced boater can be caught out, so think about those who could be put in danger if they have to help you.

You may find the following measures helpful. Not all conditions will be serious enough to need all the suggested measures.

Moor your boat in a safe place, preferably in a marina or at a recognised mooring. Limited space may be available at some locks. Moor against high banks if you can.

Ensure your mooring lines are fastened to secure fixings such as bollards, rings or even trees. Put out extra lines for more security and allow enough slack for a further rise in river levels. Do not rely on your own mooring pins or stakes, as they might not hold.

If possible, put extra fendering (such as scaffold poles or strong timber posts) between your boat and the bank side. This may prevent your boat drifting onto the river bank and becoming caught up when levels drop.

Make sure you have a safe exit ashore from your boat. If not, consider returning home or finding alternative accommodation until conditions improve.

If you are not able to vacate your boat safely and are running low on essential supplies or have other safety concerns, treat this as an emergency. Dial 999 to ask for evacuation.

Those in hire boats should stop immediately if you are advised to stop navigating. Contact your hire boat operator and follow their instructions.

Please remember your life is more important than your boat.

The Environment Agency does not provide emergency services. We are not able to carry out search and rescue, or provide supplies to stranded boats.
