Taum Sauk Plant Re-Opens
On December of 2005 the Johnson Shut-Ins State Park had mud, debris, and damage covering the area. The Taum Sauk reservoir failed, dumping more than a billion gallons of water into the park. A treasure of Missouri ruined in just 12 minutes.
Today, the Taum Sauk reservoir is rebuilt with one thing in mind... safety. The new dam has many safety features that the old reservoir didn't. Ameren UE's Vice President of Power Operations Mark Birk said, "The old dam probably had more sand and more fines in it then we would have anticipated it should have."
One of the biggest changes is the design of the reservoir. The reservoir uses roller compacted concrete which is drier and tends to crack less than regular concrete. Ameren UE is confident that this time the reservoir will hold.
Officials also say offering community support was a main priority to Ameren UE from the beginning. The construction also added 1,000 new jobs to help with the $490 million project. About 100, one foot layers of concrete complete the new upper reservoir.
Now the 440-megawatt plant stands tall. Looking out over a Missouri landmark. Johnson Shut-Ins State Park.
