A dog walker has captured the jaw-dropping moment two fishermen floated dangerously close to a huge 66ft plug hole.
Flo Neilson was walking with her two dogs past the overflow hole at Ladybower Reservoir in Derbyshire when she spotted the pair in the water.
Stunned by the sight, she began filming as they paddled terrifyingly near to the massive hole.
She told the BBC: “It appeared they were floating towards the plug hole whilst still casting their lines, but they were purposely paddling with flippers on their feet.
“It looked a dangerous and risky thing to do, but they seemed to be in control of the boats and had soon moved away after I’d stopped filming.”
Many social media users were also left taken aback by the daring duo’s actions.
One said: “I find the plug hole the scariest thing … even on video.”
Another added: “It drops about 200 feet and then a 90 degree turn and goes along to the river further down with a sluce gate.”
However some also pointed out it was unlikely the men were in danger.
One person commented: “I bet if you put the boat right to the edge it would simply bump against the plug hole and very unlikely to go down. Lip of the plug hole is only a few cm below the waterline.”
Another said: “Just to confirm, these guys are using float tubes, not boats. Their legs are beneath the water.
“They wear flippers like scuba divers. So they’d just hit the wall of the plughole. Be almost impossible to go over the edge.”

Severn Trent, which owns the reservoir, stated: “We’re glad for individuals to use our reservoir for boating and fishing, and boats can be found to rent from the fishery.
“However, we do ask that folks keep nicely away from the plug hole, as clearly that is actually harmful.
“We will be reminding everyone who uses the water to avoid the plug hole area and stay safe.”
