Feeding the Blooms
SEGMENT 1 | Lake Erie
Lake Erie’s annual toxic algal blooms are fed by runoff from agricultural land in the Maumee River watershed. Some farmers have taken steps to reduce the amount of fertilizer running off fields. But large-scale dairy and animal farms aren’t always regulated, and manure is a major source of phosphorus and nitrogen—the main nutrients that fuel the blooms..
In the Maumee watershed, by some estimates concentrated animal feeding operations, or CAFOs, produce as much waste as the cities of Chicago and Los Angeles combined.
CAFOs are regulated in Ohio law if they’re over a certain size, but if they’re just under the regulatory threshold, the rules don’t apply, and manure from cows, hogs and chicken makes its way into the Maumee River and then Lake Erie.
Crop farmers have been changing their practices to cut the amount of nitrogen and phosphorus that finds its way to the rivers, but unregulated CAFOs may be making up the difference, according to scientists studying the area.
“We’ve been trying to do it up till this point entirely voluntarily, and we’ve been trying to do this now for 10 years,” says Dr. Jeff Reutter, former director of Ohio Sea Grant’s Stone Lab. “So here we are … We see zero progress.”

High Cost of High Water
SEGMENT 2 | South Haven, Michigan
The Great Lakes have been at or near record-high water levels for much of the past year, and that high water can cost lakefront towns a lot of money. Streets are flooded, marinas are swamped and need repairs, beaches are eroded, and water treatment plants can be threatened.
“The number that we have — approximately $70 million — isn’t complete,” for statewide damage costs to towns, says Herasanna Richards, legislative associate with the Michigan Municipal League.
The group has been tallying the cost of high water to the state’s cities since 2019. Many communities haven’t even been able to estimate their costs, “and so that number has been growing by the day, by the month,” Richards says.
In South Haven, Michigan, alone the total cost to the municipality could top $20 million.
The city is making upgrades and repairs to marinas, and it’s had to protect its water treatment plants. This spring, heavy rains lead to flooding along the river.
“That day, April 30th, I was constantly running around worried. I kept checking all the spots. You lose sleep when that happens,” says Bill Hunter, South Haven’s director of public works.
The floodwater threatened South Haven’s wastewater treatment plant, but the city had installed pumps to remove water from the area in case of a flood.
“They’d only been running for a few weeks,” says Hunter. “And probably if that would have happened prior to the pumps, yes, we would have had sanitary sewer overflows, meaning the sanitary sewer would flood into the Black River and to Lake Michigan untreated. That would be the worst-case scenario.”

When the Dams Break
SEGMENT 3 | Midland, Michigan
There are thousands of dams in the states and provinces surrounding the Great Lakes.
In May, the Edenville Dam near Midland, Michigan, failed — two years after regulators pulled its license to generate power, citing safety concerns. The 21.5 billion gallons of water that had been Wixom Lake poured through the breached dam, toppling trees and destroying roads and buildings. Seven miles downstream, the deluge reached the Sanford Dam, which was quickly overtopped.
When the floodwater finally drained to Lake Huron, Wixom and Sanford lakes were empty, and the town of Sanford was in bad shape. Those failures have raised concerns about dam safety around Michigan and the Great Lakes region.
Two MLive Media Group journalists shared their insights with Great Lakes Now from their coverage of the disaster. MLive’s full coverage is HERE.
