Stay Away from Weirs and Sluices
Weirs, locks and sluices can be very dangerous – once trapped in them it can become impossible to escape
These videos from the Environment Agency explains why all rowers – no matter how experienced they are – should stay away from weirs and sluices (as well as locks and bridges) to keep themselves and others safe.

Never climb, play or swim in or around sluices. They open and close automatically without warning and when they do, they will sweep you away in a dangerous rush of water.

This video from the Berkshire Fire and Rescue Service demonstrates why swimming near a weir is so dangerous.
If you see someone in trouble in the water, the Environment Agency’s advice is:
- Call 999
- Tell them to float on their back
- Throw them something that floats.
And as explained in the next video about the effects of cold water shock, if you find yourself in trouble in the water:
- Stop swimming
- Lean back and float #FloatToLive
- Gain control of your breathing and then assess whether you can rescue yourself.
