Aging Infrastructure: Dam Safety

While dams have multiple benefits (balanced against financial and environmental costs), they can also present a risk to public safety and economic infrastructure. This risk stems from two sources: the possibility of a dam failure and the damage it would cause. Although dam failures are infrequent, age, construction deficiencies, inadequate maintenance, and seismic or weather events contribute to the possibility. To reduce the risk, regular inspections are necessary to identify potential problems. Corrective action can then be taken to remedy those deficiencies. Congress is often called upon to fund remedial actions, as a way to prevent the larger catastrophes. The 110th Congress will likely see proposals for improving dam safety and may oversee existing safety programs.
