Midland flooding highlights Michigan’s aging stockpile of neglected dams

The rushing waters out of two failed dams near Midland highlight a flood risk that extends beyond the mid-Michigan city.

In fact, the breaches are a wake-up call for the entire state as climate change, long-neglected infrastructure systems and a lack of funding all raise concerns about the condition (and investment into) Michigan’s dams. 

“The dams are very expensive and very old,” said Rebecca Esselman, executive director of the Huron River Watershed Council. “An event like Midland reminds us that the problem is not going away. In fact, it’s only getting worse as time passes.”

Following heavy rains over 36 hours on Sunday and Monday, the Edenville Dam in Gladwin County failed Tuesday, forcing evacuations of roughly 10,000 residents as water rushed into the Tittabawassee River. Located 20 miles northwest of Midland, the dam had been cited for years with safety violations


The 2018 Report Card for Michigan’s Infrastructure from the Michigan Section of the American Society of Civil Engineers painted a bleak picture of the condition of the almost 2,600 dams across the state. It gave Michigan’s dams a grade of “C-”.

According to the report:

  • Almost 300 dams — or 12 percent — have a “high” or “significant” hazard potential rating. 
  • About two-thirds of Michigan’s dams have reached their intended 50-year design life
  • Over the next five years, this number will grow to approximately 80 percent
  • There are 271 Michigan dams over 100 years old 
  • Only 86 new dams have been built in the last 25 years
  • 90 percent of Michigan dam’s with a “high” hazard rating are more than 50 years old 

The statistics are cited by Michigan organizations including environmental groups and trade associations that have been fighting to raise awareness of the need for more consistent dam inspections and repairs. 

The state averages two dam failures per year, according to the Michigan Infrastructure & Transportation Association (MITA), an industry group representing companies that work on roads, bridges and utilities. Among previous breaches: In 2003, the Silver Lake Dam north of Marquette failed, releasing 9 billion gallons of water into the Dead River. At least 1,800 people had to evacuate, and damages reached $100 million.

“We continue to say we need to invest in infrastructure,” said Lance Binoniemi of MITA. “These reports aren’t just to show they’re in bad condition, but that there could be a major failure.”

Michigan attempted to create a roadmap to fix its failing infrastructure with a 188-page report published in 2016 by an infrastructure commission set up by then-Gov. Rick Snyder in the fallout following the Flint water crisis. 

Described as “a 50-year vision for improving the state’s infrastructure system,” the 21st Century Infrastructure Report tackled energy, transportation and water issues. Among the latter: dams. 

“While many of these structures continue to serve a valuable purpose, others are in disrepair, risking failure that can cause significant ecological and economic damage, and threaten public safety,” according to the report. 

“These decades-old dams have deteriorated due to age, erosion, poor maintenance, flood damage, or antiquated design, and they are particularly vulnerable during high water flow events.”

Esselman, of the Huron River council, raised concerns over the cost of dam maintenance, repair and insurance. The solution, according to the 2016 report, would require a $227 million investment in additional state funding over the next 20 years. Esselman said “the dam owners, which are often small cities and towns, are bearing the burden of the cost.” 

Despite the roadmap, state officials still haven’t prioritized dams, Bioniemi said, with legislators showing little response to calls for action.

“We have seen a little progress on the federal side, but obviously not enough,” Bioniemi said, noting investment in the Soo Locks as an example. The state also contributed toward $75 million in recent upgrades to the shipping facility in Sault Ste. Marie.

The situation in Midland, he said, calls into question whether dams should even be privately owned. The failing dams there have been owned by Boyce Hydro, which has sold dam-generated power to Consumers Energy.

Experts say Michigan’s high water levels mean more breaches are possible as climate change contributes to record-setting rainfall levels. The Great Lakes already are at 1986’s record-setting levels with forecasts indicating they may exceed that this year.

“This infrastructure was designed for a certain set of conditions at a particular location,” Esselman told Bridge.

“With climate change, we are regularly seeing sets of conditions that go considerably beyond what the infrastructure was designed to handle.”

The state’s lakes and rivers were full before this week’s rain, which created a regional problem over 36 hours when roughly 8 inches of rain fell in Au Gres and East Tawas—about double what fell in Midland. Rising Great Lakes water means there’s no place for that kind of rainfall to quickly drain, said Jerrod Sanders of Michigan's Department of Environment, Great Lakes and Energy.

While investigations will address the causes of the dam failures in Midland, Sanders said, “ultimately, this is all being driven by unprecedented amounts of rain.”

Sanders is coordinating efforts related to the state’s high water, which in 2019 largely focused on Great Lakes shorelines. However, he said, inland waterways are increasingly becoming a priority.

“The inland high water increase is becoming a much bigger deal as we move into 2020,” Sanders said. 

That means the state is likely to see more infrastructure damage. Some may involve dams, but other structural damage is happening to both public and private property, he said.  “This is a Michigan-wide problem,” Sanders said. 

Meanwhile, dealing with the Midland flooding during the coronavirus pandemic makes the situation even harder, Binoniemi said. But the current focus on COVID-19 doesn’t mean infrastructure needs are on pause.

“This is a clear sign that, yes, the world has been taken over by COVID and every priority has been focused on that,” Bioniemi said. “In the meantime, our infrastructure is still deteriorating and we’re going to have to pay for it eventually.”

Why do you refer to your reporting as "Michigan's nonpartisan, nonprofit news source" when you are clearly pushing the Leftist agenda of "climate change?"

I assume you don’t believe in climate changes. There are indicators throughout the world showing the results of climate change. Air that one needs to islook them up!

Thanks for the timely reporting and background. We have a private dam in Brighton that has been used for nefarious development efforts to enrich some insiders. We need clear, professional administration by a government. Not amateurs seeking to sell off dam property and rig maintenance assessments for profit.

This "emergency" is just one more example of the long term results of fifty years of neglecting the infrastructure of our state and nation, meaning not just the roads and the bridges, but the water and sewer systems, the power grid, and the flood control dams. There are thousands of dams, but only a few were originally and specifically built to control floods downstream. Some, however, although built for other reasons, enabled folks living downstream to occupy and use land which would otherwise have been within an obvious flood plain. And that's what we have in the Midland disaster.
On a larger scale, this is what we get each year in the Missouri River Valley. Many of those dams were originally built to minimize downriver flooding, and to enable irrigated agriculture. But over time, the shoreline became upscale recreational property, owned by many folks who were the movers and shakers in their communities. Flood control means that you need to drain the lake during the winter season, and not refill it until the Spring rainy season is past. That enables it to catch and hold the Spring overflow. But shoreline owners can't wait for that season to crest. No matter who is in "control", there are heavy unpublically spoken expectations to restore these shorelines to full capacity. Unfortunately, our democratically elected officials tend to respond to those expectations, always hoping that nothing bad will ensue.
