Inspections, Evaluations and Modifications for Corps of Engineers Dams

by Arthur H. Walz, Jr., US Army Corps of Engineers, Washington, United States,



Document Type: Proceeding Paper

Part of: Geotechnical Practice in Dam Rehabilitation

Abstract:

The Corps of Engineers owns and operates 580 dams in the United States. As these dams become older (199 are over 50 years old), dam safety and modifications play an increasing role in their operation. Seepage and overtopping remain the major causes of failure for large dams in the United States. The periodic inspection and evaluation program allows our engineers to monitor their performance and design remedial modifications as required. In the past two years $94.4 million was spent on major dam safety modifications at six projects. Another $19.0 million was spent on minor construction related to dam safety at 20 projects.
