Be Seen, have support

Swimmers may be able to see boaters but boaters may not be able to see swimmers!

  • Have a safety boat or canoe support displaying a white and blue Alpha flag Blue and white Alpha flag, warning of divers or swimmers in the water.
  • Wear a bright swim cap and tow a bright float.
  • Never swim alone.

Take a look at the photos below. If you were steering a boat, which swimmer is easier to spot?

Be Water wise

Exposure to cool water can rapidly lead to hypothermia

  • Wear a wetsuit to keep you warmer and more buoyant.
  • Enter the water slowly to get used to it.
  • Check the depth and the water bed by walking in carefully.
  • Don't jump in.

Be Informed

Other people use the lakes too! Windermere, Derwentwater, Coniston Water and Ullswater are busy with boats. People on boats may struggle to see swimmers. A collision with any boat can be fatal.

  • Tell someone where you are going and when you expect to be back.

Be Mindful

  • Choose one of the quieter lakes that do not allow boats.
  • Avoid mooring areas, marinas and jetties used by boats, ferry routes and boating channels.
  • Be aware boaters may be in any area of the lake at any time of day or night.
  • Only swim when weather conditions are suitable - remember they can change quickly.

Help native wildlife

Invasive non-native species of wildlife can hitchhike on equipment, footwear, clothing and boats. You may inadvertently spread the aliens even if you just go for a paddle! Every time you leave any water such as a river, tarn or lake:

Check - Clean - Dry

Stop the spread of invasive aquatic species logo

  • Check your equipment and clothing for living organisms. Pay particular attention to damp or hard to inspect areas.
  • Clean and wash all equipment, footwear and clothes thoroughly. If you do come across any organisms, leave them at the water body where you found them or on a hard surface to die out.
  • Dry all equipment and clothing. Some species can live for many days in damp conditions.
