The term 'fundamentally swapped' is vague. I wonder if the salinity levels remained uniform across the lake or if it created a stratified layer.

That stratification point is wild... especially considering how those salt domes are structured. I wonder if the pressure differential during the collapse actually forced salt water up into the freshwater table...

The 'corporate error' usually boils down to bad surveying. When you are dealing with subsurface salt deposits, a few feet of miscalculation on a map is the difference between a project and a sinkhole.

The recovery effort was actually quite a feat of engineering. Seeing how they managed to stop the flow and stabilize the area is a testament to quick thinking under pressure.
