Pumped hydro is really cool. Also really bad when it fails:

> ... catastrophic failure of a triangular section of the reservoir wall and the release of 1 billion US gallons (3,800,000 m3) of water in 12 minutes. The sudden release sent a 20-foot (6.1 m) crest of water down the East Fork of the Black River.

> A broad swath of dense forest was washed away and scoured to bedrock by the escaping flow.

A tidbit that will be interesting to any programmer or engineer: one of the causes of the failure was that the high-water gauges were moved to above the height of the dam wall because someone was annoyed by false positives.

Taum Sauk is unusual in that the dam fully surrounds the upper reservoir (i.e. the lake was made from scratch), although certainly all types of dam can fail.

All types of dams can be shittily maintained:

Sounds like they hired Homer Simpson to operate the plant.
