Taum Sauk began operation in 1963, with an upper reservoir built of earth atop a hill in Missouri. 0000004615 00000 n Initially the generating capacity was 2 x 175 MW turbine-generators, but this was upgraded in 1999 to 2 x 225 MW. The Upper Reservoir was the first hydroelectric facility worldwide capable of remote control that did not require system operation personnel on site. On December 14, 2005, near the end of the morning pumping cycle, both the primary reservoir sensors and the “fail safe” Warrick probes failed to report the critical high water level in the reservoir because the probes had been incorrectly set at a higher elevation than the low point on the parapet. Case History Summary:  Taum Sauk Storage Dam Failure, Lessons Learned, and the Rebuild. 0000069571 00000 n Pumped storage embankment dams should have an emergency spillway or other redundant features to prevent overfilling and overtopping of the embankment. The 2005 Upper Taum Sauk Dam Failure: A Case History J. DAVID ROGERS; J. DAVID ROGERS 1. USSD Annual Conference. Talk:Taum Sauk Dam Failure. 0000080807 00000 n Until repairs on these deflected conduits could be properly executed, several precautionary measures were taken. ABOUT US. New embankment dams should be designed with allowances for settlement. The two original reversible pump-turbine units were each capable of generating 175 megawatts of power. Malfunction – Taum Sauk Dam Failure. (4) Watkins, C. & Rogers, J. This paper will discuss the challenges encountered with the foundation at the Taum Sauk Upper Reservoir Dam and the Wyaralong Dam. 0000074343 00000 n 0000073417 00000 n All rights reserved. To their surprise, they noticed water pouring over one of the edges of the dike in a manner that resembled “Niagara Falls.” System operators immediately worked to manually disable the pumps and control the water level, averting disaster. 96 0 obj <> endobj Many years of successful dam performance does not guarantee future successful performance. �k8Xe� ���0t 0000071531 00000 n xref As a result, the pressure transducers’ ability to report accurate water levels was hindered, and lower water levels were being recorded than actually existed. The disaster at Russia's biggest power plant, which left dozens dead, could have been prevented, according to the head of the Russian Accounts Chamber. Le projet est situé à/en Reynolds County, Missouri, États-Unis, USA. 0000079303 00000 n The committee also gathered information on the KaLoko Dam failure (Hawaii) and the levee failures in New Orleans.
