Tempted to take a dip to cool off in a Surrey river, lake or reservoir? Read our essential safety tips before you do…

When hot weather arrives, it’s tempting to seek solace in natural water bodies like rivers, lakes and reservoirs. 

However, beneath their tranquil surface can lie hidden dangers. In this article, we'll explore the risks associated with swimming in rivers and reservoirs and provide essential tips to ensure your safety.

Beware the undercurrent 

Strong fast-moving currents below the surface often created by the water's natural dynamics can get anyone in trouble, regardless of whether they can swim or not. Getting caught in one can be frightening and exhausting, so like anything to do with water, knowledge is power!

Familiarise yourself with the telltale signs of an undercurrent, such as water that appears darker or more agitated than the surrounding area. Be cautious when swimming near bridges or dams, as these areas are more likely to have strong undercurrents.

Always pay close attention to warning and safety signs. These signs are there for your protection, and ignoring them can have dire consequences.

If you are not a strong swimmer, stick to shallow areas where you can easily reach the safety of the shoreline if you encounter an undercurrent. 

Hidden dangers lurking on the bottom

We’ve all seen the kids jumping off local bridges or weirs, but it goes without saying that this can be extremely dangerous; you should never plunge into the water if you're unsure of its depth, the speed of the current or whether there are obstructions below. It’s often impossible to know what lies beneath - and rivers in particular, can have all sorts of hidden waste or structural supports that can cause injury. Remember, rivers are most definitely not the same as swimming pools.  Without knowing what’s down there, we can never be sure it’s 100% safe. 

Drink, drugs and water: A terrible mix

Shockingly, 27% of all accidental drownings in 2020 involved the influence of alcohol and/or drugs. Remember, if you suspect someone isn’t fit to enter the water safely, there is absolutely nothing wrong with being the voice of reason; it’s the same principle with drinking and driving; it’s totally acceptable - in fact, it’s totally expected nowadays - to actively discourage someone from getting behind the wheel of the car if we know they have had too much to drink. The same applies to swimming - you may just save a life. 

Cold water shock: the silent killer

If you find yourself unexpectedly immersed in cold water or you dive in and are shocked by the cold, your natural instinct may be to thrash about, but it's important to fight that urge. Cold water shock is a silent killer, and it's imperative to remember the advice from the RNLI: 'float to live.' Try to relax and give your body a chance to catch its breath.

Check the water quality

While the beauty of rivers and reservoirs may draw you in, it's essential to consider water quality when deciding to swim in them. Unlike regulated swimming pools, natural water bodies can host a variety of contaminants that pose a risk to your health. These contaminants can include bacteria, algae, and pollutants from runoff, sewage, or industrial waste.

Before heading to a river or reservoir for a swim, check local water quality reports. Many environmental agencies provide regular updates on water conditions, including the presence of harmful bacteria or algae blooms. Avoid swimming if the water quality is questionable.

Stagnant or slow-moving water is more likely to harbour harmful microorganisms. Choose areas with flowing water whenever possible, as it is generally cleaner and less likely to contain pollutants.

After swimming in natural water, be sure to shower thoroughly and wash your swimsuit. This can help remove any potential contaminants from your skin and clothing.

Safety equipment for the open water

Whether you're a seasoned swimmer or a novice, it's crucial to be prepared when swimming in open water. Proper safety gear and basic knowledge can significantly reduce the risks associated with natural water bodies.

Wearing a life jacket is especially important if you are not a strong swimmer or if the water conditions are challenging. A life jacket can provide buoyancy and keep you afloat, even in the presence of strong currents.

Swimming alone in rivers and reservoirs is not advisable. Always swim with a friend or family member who can assist you in case of an emergency.

When taking part in water-based activities like paddle boarding or kayaking, it’s a good idea to carry a flotation device, such as an inflatable raft or inner tube, to help you stay afloat if needed. Additionally, bring a basic first aid kit, a whistle to signal for help, and a fully charged cell phone in a waterproof case.

Make sure someone knows where you are

If you are intending to swim in the open water make sure someone knows your whereabouts and your estimated time of return. It's a simple precaution that can make a world of difference in case of an emergency.

Lastly, never push your limits when swimming in natural water bodies. If you feel tired, experience cramps, or notice signs of fatigue, exit the water immediately.

Remember, it's better to be safe than sorry when it comes to swimming in unfamiliar waters.
