Aging Dams and Clogged Rivers: An Infrastructure Plan for America’s Waterways

Friday, October 21st, 2016
FIGURE 1 Number of dams per age range, by 2020

Functional or not, the dams that dot the country cannot simply be ignored or forgotten. Indeed, these dams pose a significant safety problem: ASCE classifies nearly 4,000 dams as “deficient.” Furthermore, these structures continue to block an estimated 600,000 miles of rivers in the United States. A new analysis by the Center for American Progress for this report demonstrates that dams and reservoirs have modified the flow of 71 percent of Western rivers by length and that Western rivers are 66 percent more fragmented than they would be in their natural state.

Jim Pawloski

Jim Pawloski is President of the Association of State Dam Safety Officials. He has been a dam safety engineer with the Michigan Department of Environmental Quality since 1989. Jim spent five years with STS Consultants (now AECOM) prior to joining the State of Michigan.

“…What we’re trying to do with the Association of State Dam Safety Officials is to improve the condition of dams and improve the safety of dams and the safety around dams.
