That report isn’t true. A pump didn’t fail. Several sensors used to report when the reservoir was full, failed over a period of time. The company management didn’t want to pay for the labor to replace those $10 sensors. When the last sensor failed, water was pumped into the upper reservoir until it started overflowing. That eroded the side of the reservoir until it collapsed and it drained.
There were other reasons too. The material used to build the damn was supposed to be only rock, but they used more soil than they were supposed to. It caused setting, which lowered the walls by 2ft in some sections. They adjusted the sensors to kick off the generators at 2 ft lower than they were initially set to. This was all done to mitigate the issue of the sensors floating, until they could do proper repairs during the yearly maintenance window. There was not one smoking gun, but a series of events that caused the failure. They also didn't have a spillway. They have solved most of these issues now.
I love Johnson’s Shut-Ins and the restoration did a great job of rebuilding the park in a way that resembled it’s original look, even moving the river’s boulders back into place.

But it was poor programming on pump. They should have shut off after so many hours when the high level was not reached. Simple programming
interesting engineering question
This. Ameren was to blame for this.

Johnson’s shut-ins renovations has made it one of the nicest and most updated parks. Highly recommend visiting if you get the chance.

Never money to build it right.
Always money to build it again.
Ameren was to blame for this reservoir breach, through and through. Don't let anyone tell you otherwise!!
Johnson Shut-Ins has NOT been restored. This is a lie.
What are you talking about? It’s like the nicest state park in Missouri now.
First newscaster looks rough
Isnt that the reason for those things orange signs that say "if warning siren sounds immediately leave area go up hill 200 steps"?
Yes.
