NI Water is appealing to the public to take care of their dog and ensure they are on a lead when visiting any of its popular visitor spots.
Many of Northern Ireland's most beautiful sites from parts of the Mourne Mountains to the Garron Plateau, are owned by the public utility company and often used by local farmers to graze livestock.
Rebecca Allen, NI Water catchment officer said: "NI Water is proud to host visitors to many of these sites. However, visitors are reminded that the policy across all NI Water sites is to keep dogs on leads at all times - this is to ensure the safety of both your pets and local wildlife.
