A woman was rescued from the River Uck near Uckfield Rugby Club yesterday after she went into the water to help her dogs.
Firefighters used water safety equipment to reach her and the dogs, then the woman was left in the care of an ambulance crew.
A spokesperson for East Sussex Fire and Rescue Service said: “Following the successful rescue from the River Uck ESFRS would like to remind everyone of the dangers of being in, or near, water.
“Water temperatures are dropping rapidly now, and hypothermia is a very real danger to anyone not wearing the appropriate clothing.
“Another real issue is the unseen dangers beneath the water’s surface that are not readily visible. With the murky consistency of the Uck you cannot see objects in the water and it is difficult to work out how fast the water is flowing.”
The fire service said it strongly advised people to avoid entering the water to rescue pets.
“If you come across a person in danger, in or near a body of water, dial 999 immediately with as much information as to the exact location as possible and please remember the Shout, Reach, Throw principle to assist the person in trouble, but keep yourself safe.”
