YORKSHIRE Water is urging visitors to its reservoirs to take care throughout the spring and summer.
The start of lighter evenings and warmer weather sees a rise in people heading into the countryside.
And Yorkshire Water says that whilst it is keen for the public to enjoy its sites, visitors are encouraged to behave responsibly.
People are reminded that swimming in reservoirs is prohibited, as is the use of disposable barbecues on Yorkshire Water land.
Visitors are asked to take litter home, and to keep dogs on leads.
Ranger teams will be out and about speaking to visitors.
David Spencer, lead ranger with Yorkshire Water, says: "We want people to enjoy coming to our reservoirs but it's important that those who do don't take risks that could impact the natural environment and wildlife, or put them in harm's way.
"Parents should stay alert to their children being tempted to enter the water. Sadly, we’ve seen incidents in recent years when people have lost their lives in reservoirs.
"Also, following the Countryside Code and ensuring you take litter home, keep dogs on leads, park considerately and be friendly to other visitors will help make trips to our reservoirs enjoyable for everyone."
