Written By: Samantha Justice, P.E. Dams and Spillways Are a Critical Part of U.S. Infrastructure With estimates of 84,000 structures nationwide, dams and spillways are essential for controlling flooding, water distribution and management, and providing hydroelectric power. Unfortunately, these structures cannot last forever. The average age of dams and spillways in the US is 57 years, seven years over the typical 50-year lifespan of these structures. Aging infrastructure can lead to serious consequences if safety precautions are not taken, or measures are not implemented to address identified problems in a timely manner. The most important measure that any dam manager can apply is continual inspection and upkeep. The US Army Corps of Engineers Infrastructure Report Card rating for 2021 was a C-, and the health of dam structures was a significant part of that low rating. State and federal regulations provide a framework for the assessment and maintenance of dam and spillway structures-at a minimum yearly audit inspections that identify areas that need repair or replacement are required. Performing these repairs can help extend the lifetime of dams to help keep essential services in place without excessive cost or increased failure potential. Understanding Areas of Concern for Existing Structures The… Read more »
