Hello everyone and welcome back to Scary Interesting.

On the channel we've covered horrific industrial accidents before.

We've also covered dozens of dive stories where something disturbing has happened to someone deep in the water.

In this video though, we're going to look at three stories that are at the intersection of these two categories.

And there are few worse things than I can imagine happening

than what happened to the poor souls in the third story.

So as always, viewer discretion is strongly advised.

Along the Chattahoochee River near Columbus, Georgia, the Lake Oliver Dam operates as an important part of the region's power grid.

The dam was completed in 1959 and its construction created the Lake Oliver Reservoir.

Since its establishment, the facility has been owned and run by

Georgia Power and the dam produces power using four hydroelectric turbines. Water from Lake

Oliver is directed through the structure and into those turbines, where its movement

is converted to electricity before continuing on downstream. Although that process sounds

simple enough, making it work requires careful management inside the dam.

Water has to be rooted through internal pipes in a specific sequence, and that sequence depends

on several mechanical components working together.

Head gates regulate when water is allowed into the system, valves then control how water

enters large pipes called penstocks, which carry it directly to the turbines.

Chains are then also used to operate some of those gates.

When everything is functioning properly, operators can control the system with precision.

When something goes wrong, however, sometimes even a single failure can disrupt operations and require direct inspection inside the dam.

Now, before a turbine can be activated, its penstock must be filled with water.
