WATCH: Police chief, 66-year-old man, and dog rescued after falling through Mantua Reservoir ice

MANTUA RESERVOIR, Utah (ABC4) – Dramatic body camera video shows officers saving 66-year-old Larry Magnum and his dog’s life after falling through the ice in Box Elder county.

Mantua Police says Magnum was making his way across the frozen lake to fish when the ice broke beneath him. He was clipped into a sled by webbing and carabiners, which immediately sank, pulling both his dog and himself into the frigid water.

Magnum then grabbed the dog, a malamute mix, put him on his shoulders, and started treading water.

Mantua Police Sgt. Josh Jefferies tells ABC4 that, “a person saw the man fall into the water and called 911.”

Mantua officers say it reminded them of the Navy Seals water challenge except in ice-cold water, carrying a dog, and being clipped to a sled.

Utah Highway Patrol Trooper Castillo was first on the scene, with Police Chief Michael Castro arriving a couple of minutes later.

Chief Castro grabbed a small flotation device and rope from his car and both officers went on to the ice.

Chief Castro and Trooper Castillo moved quickly, working together to help get a rope out to Magnum. While trying to get the man out, the ice broke below the chief, and he also fell into the water.

According to Sgt. Jeffries, Chief Castro, and Trooper Castillo didn’t stop trying to get to Magnum out, even though the chief was in the water.

Trooper Castillo held the rope, the chief climbed out of the water, then freed the Magnum from the sled, got the dog back onto the ice. After that series of events, the officers were then able to get the Magnum above the ice.

The Brigham City Fire Department Ambulance, Rescue, and Fire Chief arrived with special ice rescue equipment and dry suits to complete the rescue and get all three men and the dog off the ice.

Mantua Police said the Magnum suffered minor lacerations and mild to severe hypothermia. The dog also suffered lacerations and hypothermia.

Both the dog and Magnum are expected to make a full recovery.

Following his harrowing rescue, Larry Magnum warns “the public to be careful because ice isn’t thick enough and it’s not always safe.”
