The Taum Sauk Upper Reservoir Dam Restoration Project was named the recipient of the Award of Excellence in the Constructed Project. On December 14, 2005, a 700-foot section of the rockfill dike surrounding the Taum Sauk Upper Reservoir near Annapolis, Missouri, failed, releasing 1.4 billion gallons of water. The new Upper Reservoir, completed in late 2009, involved a complete rebuild of the dam, making it the largest Roller Compacted Concrete dam in North America. The project is owned and operated by AmerenUE, Missouri’s largest electrical utility company. The project was designed by Paul C. Rizzo Associates, LLC; Ozark Constructors, LLC, A Fred Weber – ASI Joint Venture, was the contractor; and construction management services were provided by Rizzo.
Use of Hi-Resolution LiDAR in Discovering the Polaris Fault, Martis Creek Dam, Truckee, California, a paper co-authored by Lewis E. Hunter and Ronn S. Rose, Corps of Engineers; Bruce R.
