$180 Million Settlement in Reservoir Failure

On December 14, 2005, the upper reservoir of the Taum Sauk pumped storage plant, a hydroelectric power plant in the Missouri Ozarks, suffered a catastrophic failure. The resulting flood severely damaged the Jonhson’s Shut-Ins State Park and swept away the park superintendent and his family. Fortunately all of them survived.

Last week, the Missouri Attorney General’s office announced a settlement of $180 million between the facility’s owner, Ameren Corp. The failure reportedly was a result of negligence on the part of the company. More details after the break.

27 Years Ago: Bizarre Drilling Disaster at Lake Peigneur

I thought the 17 27 year anniversary of this unique geological disaster was occasion enough for another look. On November 21, 1980 a Texaco oil rig was drilling an oil exploration well from Lake Peigneur in Southern Louisiana when the drill stem punched into the third level of the nearby Diamond Crystal Salt Company as a result of a miscalculation (understatement!). The lake, approximately 2.5 BILLION gallons, drained into the mine taking the drilling platform with it and another 11 barges, trees, and some of the surrounding terrain. As if that weren’t enough, the Delcambre Canal which normally flows from the lake into Vermillion Bay actually reversed flow for several days and filled the mine and the lake with salt water. It also temporarily created Louisiana’s tallest waterfall at 164-ft (see photo at left). Read on for more info, video, maps, and links.

The remediation involved some very interesting geotechnical issues.
