Description
Summary:As dams age, maintenance needs and safety concerns increase. Dam safety officials are placing greater emphasis on automated instrumentation, monitoring and reporting systems. A look at the Tolt Dam near Seattle shows how such systems work. The city of Seattle's power authority, Seattle City Light, completed construction of a new hydroelectric facility to the Tolt Dam in 1995, taking advantage of the considerable head in the Tolt system and bring in the Tolt Dam under the authority of the Federal Energy Regulatory Commission. The new upgraded system includes advance warning capabilities, the automation of daily dam safety monitoring activities, and a new data management plan with associated database.
