Michigan just had two dams collapse. Michigan has a D+ infrastructure rating from the American Society of Civil Engineers. Michigan has a C- for its dams.
Michigan’s approximately 2,600 dams support water supply, irrigation, hydropower, and in some cases, recreation. There are 140 high hazard potential dams in the state. Hazard potential is not an indication of the dam’s condition, but an indication for the potential for loss of life and property damage if the dam were to fail.
According to the 21st Century Infrastructure Commission Report, $225 million is needed in additional state funding over the next 20 years to manage the aging dams in Michigan.
The 2017 Infrastructure Report Card reveals that the USA made some incremental progress toward restoring our nation’s infrastructure. But it was not been enough. As in 2013, America’s cumulative GPA is once again a D+.
The average age of the 90,580 dams in America is 56 years. As our population grows and development continues, the overall number of high-hazard potential dams is increasing, with the number climbing to nearly 15,500 in 2016. Due to the lack of investment, the number of deficient high-hazard potential dams has also climbed to an estimated 2,170 or more. It is estimated that it will require an investment of nearly $45 billion to repair aging, yet critical, high-hazard potential dams.
