Sturgis is getting a little more runway before it has to pull the plug on its century-old hydroelectric dam reservoir. City officials say a federally ordered three-foot drawdown of the impoundment, originally supposed to be wrapped up by next Wednesday, will now be finished by Sept. 15. The city plans to start lowering the water on Sept. 8, setting up a tense clash between federal dam safety concerns and downstream environmental worries in this farm-heavy stretch of Michigan.
In a city news release last Thursday, Sturgis said it received a formal extension from the Federal Energy Regulatory Commission that pushes the required lowering into September and buys time to coordinate repairs. City of Sturgis said FERC completed an on-site inspection before signing off on the extra window and that the delay lets local officials better stage the work and give upstream residents a heads-up.
Regulators flagged problems at the embankment
FERC first ordered the drawdown in May after inspectors found ongoing deterioration at the dam’s left embankment, including seepage along the toe and signs that material was shifting near the spillway. WLKM reported that the commission labeled the three-foot lowering an "interim risk-reduction measure." City managers told local outlets they had been working with FERC on long-planned embankment repairs and asked for more time so upstream users would not take the full hit in the middle of summer.
FERC conditions, paperwork and the timeline
According to a FERC letter and city filings, the commission agreed to Sturgis’ request to delay the three-foot drawdown to Sept. 15 but attached several strings, including a limit on how fast the water can be taken down and tighter monitoring requirements, and told the city to file an updated drawdown plan by July 31. As laid out in the city’s public notice, the reservoir will be lowered at a rate of no more than six inches per day, with river levels affected for roughly five miles upstream. MLive and the city’s drawdown notice describe how repair timing and refill restrictions are tied to environmental windows for refilling.
State and farmers push back
The Michigan Department of Natural Resources opposed giving Sturgis more time, arguing that exposed riverbanks might not stabilize before spring rains and high flows, which could ramp up erosion and sediment washing downstream. WLKM reported on the DNR’s objections, and local coverage has pointed out that farmers depend on the impoundment for irrigation. A summer drawdown can leave intake pipes high and dry and fields short on water. Wilcox Newspapers has charted about five miles of upstream impacts and reported that several farms fall within that zone.
What residents should know next
The city’s public notice tells boat owners to move or secure their watercraft and warns that the impoundment will not be refilled between Oct. 15 and May 1 while repairs are underway. Officials expect construction to start in spring 2027 and to last several months, and local reporting says both the work and its price tag will be covered through municipal electric rates. City of Sturgis provides contact information for questions and more details in the formal drawdown notice.
