Lake Michigan Water Levels in 2026: What Lakefront Owners Need to Know About Erosion Risk
Anyone who lived on the Lake Michigan shoreline through 2019 and 2020 remembers what high water looks like. Bluffs collapsed. Decades-old seawalls failed. Beaches disappeared in a single storm. The lake then drew down through 2022 and 2023, and the headlines moved on. Owners with intact walls breathed out. Owners watching their bluff retreat at half a foot a year started thinking they could wait.
That instinct is the most expensive mistake we see along the lake. The lake cycles. It always has, and the long-term records from the U.S. Army Corps of Engineers Detroit District and NOAA's Great Lakes Environmental Research Laboratory document multi-foot swings on rolling 5 to 8 year intervals. Spring 2026 is the kind of window when the right shoreline owner can do permanent work at lower cost, with a faster permit, and with the structure ready before the next high cycle. Below is the read-out we share with clients across Michigan, Indiana, Illinois, and Wisconsin.
Where the Lake Sits Right Now
Lake Michigan and Lake Huron are hydrologically a single lake at 577 feet International Great Lakes Datum 1985, with the connection at the Straits of Mackinac. The Army Corps publishes one combined monthly bulletin for Michigan-Huron. The current level reads close to the 1918-2025 long-term mean, which puts the lake well below the high-water datum used for regulatory shoreline assessments and several feet below the 2020 monthly peaks.
What that means in real terms on the shore:
- Beaches are wider than they have been in five years on most stretches.
- Toe-of-wall conditions are accessible for inspection and repair on most properties.
- Wave run-up is reaching seawall caps far less frequently outside major storm events.
- Ice formation through last winter sat lower on the wall than the 2019-2020 winters did.
That picture is calmer than the recent past. It is not permanent. The lake bottom does not change. The wall does not move. The water level is the variable, and the variable is doing what it always does.
How the Cycle Has Moved Since 2020
Looking at the Army Corps monthly mean tables, the Michigan-Huron cycle since 2020 has run something like this. The 2020 monthly peak landed in the upper end of the historical range, well above the long-term mean. By summer 2022 the level had dropped roughly two feet. Through 2023 and 2024 it stabilized close to the long-term mean. The current 2026 reading is in that same near-average band.
Compare that to the previous big cycle. The 2013 monthly low was below the historical low of record. By 2020 the lake had risen more than five feet from cycle low to cycle high. That move took seven years. The bluff loss, the seawall failures, and the insurance claim spikes all clustered in the back half of that rise.
Here is the same pattern simplified for a lakefront planning conversation.
| Phase | Approximate level vs long-term mean | Risk profile for shoreline owners |
|---|---|---|
| 2013 cycle low | Well below mean | Beaches expanded, low erosion pressure, deferred maintenance widespread |
| 2017 to 2018 mid-cycle | Above mean and rising | Wave run-up reclaimed beach, owners scrambled for permits |
| 2019 to 2020 cycle high | Near record-high | Bluff collapses, wall failures, emergency armoring, multi-month permit backlogs |
| 2022 to 2023 draw-down | Back near mean | Repair window opened, contractors caught up, permit queues normalized |
| 2026 current | Near long-term mean | Planning window: best conditions to fix wall, drive sheet pile, place stone |
The lesson the Lake Michigan record keeps writing is that the work owners do during a near-average year almost always pays off. The work owners try to start during a high-water year almost always costs more, takes longer, and gets compromised by the conditions.
Why a Lower-Level Year Is the Right Time to Build
Three factors line up favorably during a near-average year that disappear during a high cycle.
Construction Access
Driving steel sheet pile, placing stone, or rebuilding a tieback system requires reach to the toe of the wall. When the lake is high, that toe is underwater and barge work or coffer-dam work becomes the only option. Costs jump. When the lake is closer to mean, much of the work can be done from land or barge in shallower draft. Heavy equipment can stage on the beach without conflicting with the active wave zone.
Permit Timing
State agencies (Michigan EGLE Part 325, Indiana DNR, Illinois IDNR, Wisconsin DNR) and the U.S. Army Corps of Engineers all run faster permit cycles when the application is for proactive repair than when it is an emergency response. Emergency armoring permits during a high cycle are real but they often carry conditions, time limits, and re-engineering requirements. Standard permits during a calmer year are cleaner and usually faster.
Material and Crew Availability
During the 2019-2020 high cycle, sheet pile lead times stretched and qualified marine crews were booked months out. Coastal engineers were maxed. None of that is true right now. Crews are available. Materials are stocked. Quotes hold for weeks instead of days.
The combination is unusual and worth using. We have seen complete seawall replacements in 2026 quoted at meaningfully lower cost-per-linear-foot than the same scope quoted in late 2020. The water level is the structural reason.
Ice Damage and the Winter the Wall Just Survived
Ice is the second-largest seawall threat behind direct wave action, and ice damage scales with where the water meets the wall. Lower lake levels through last winter meant ice formed lower on the wall on most properties. We have seen less heave damage on caps and less stress on tiebacks coming out of the 2025-2026 winter than in any of the preceding five winters.
That reduces the urgent repair list this spring on most walls. It also opens a window. Walls that survived the 2019-2020 cycle with hidden damage often show that damage now, when it can be diagnosed without the wave action obscuring the toe. Anything we find this spring is fixable cheaply. The same finding during a high-water year would be a much harder repair.
The decision tree for owners who weathered last winter looks like this: pay for an inspection now, document what's actually there, repair the small items, and engineer the big items so they're ready to bid when the next cycle starts. Waiting until the lake comes up is the path that produces emergency calls.
What Long-Term Records Suggest About the Next Cycle
Predicting the lake is a hazardous business, and any responsible coastal engineer will say so out loud. NOAA Great Lakes Environmental Research Laboratory publishes a six-month forecast each month, and the longer-range outlook shows wide uncertainty bands. What the historical record does say with confidence is that the lake does not stay at average for long. Cycles run on the order of five to eight years between high and low. The last cycle ran 2013 low to 2020 high, then drew down by 2023.
If the lake is currently near average and the historical pattern repeats, the next noticeable rise would begin within the next two to four years. That is a planning horizon, not a panic horizon. It is also not a "we have a decade" horizon.
Owners who treat the next two summers as the build window and the following five years as the high-water defense window have done well historically. Owners who treat the calm year as confirmation the threat is gone have repeatedly paid for that interpretation in emergency repair bills.
What to Do This Spring
Five concrete steps cover most lakefront properties in the planning window we're in:
- Schedule a professional seawall inspection while the toe is accessible. Document cap, face, toe, tiebacks, and drainage.
- Repair small items now. Cracks, joint separation, rip-rap voids, and minor tieback issues fix cheaply during a near-average year.
- Engineer the major items. If the wall is approaching end of life, get the design done and the permit application drafted now so the project is ready when conditions warrant.
- Review the permit picture. Michigan EGLE, Indiana DNR, Illinois IDNR, and Wisconsin DNR all have nuances. The Army Corps Section 10 jurisdiction layers on top.
- Build the binder. Photos, deeds, prior permits, and the most recent survey all matter to insurance and to future buyers if the property changes hands during a high-water year.
None of these steps is dramatic. All of them compound. Owners who run this list in 2026 typically end up with a more durable shoreline at lower total cost than owners who wait for the lake to make the decision.

What is the current water level on Lake Michigan in 2026?
Spring 2026 water levels on Lake Michigan-Huron are running near the long-term average, several feet below the record-high cycle of 2019 and 2020. The Army Corps Detroit District publishes monthly bulletin readings that lakefront owners can pull directly. Levels remain dynamic year to year, and seiche events can swing local readings sharply over a few hours.
Are Lake Michigan water levels still falling?
Levels stepped down from the 2019-2020 highs and have moved within a narrower band since 2023. Forecasts from the Army Corps and NOAA Great Lakes Environmental Research Laboratory project a continued near-average pattern through the 2026 navigation season, with normal spring rise into summer and gradual fall draw-down. The lake has not stopped cycling. It is between extremes.
Should I build a seawall while levels are lower?
Yes, in most cases. Lower lake levels mean better access to the toe of the existing wall, better conditions for sheet-pile driving, and a longer dry-work window. Permit reviews also tend to move faster when no emergency armoring is being requested. Building or reinforcing a seawall during a lower-level year is the right play if the long-term trajectory points toward another high-water cycle, which the historical record strongly suggests.
How fast can the lake rise again?
The historical record shows Lake Michigan-Huron can swing more than four feet between low and high cycles within a 5 to 7 year span. The 2013 to 2020 rise added roughly six feet from cycle low to cycle high. A wet year with heavy lake-effect snowpack and high spring runoff can move the lake up six to ten inches in a single season. Owners who plan for a stable lake usually lose money.
Does ice damage scale with lake level?
Indirectly, yes. Higher lake levels push wave run-up further onto bluffs and across cap surfaces, so winter ice forms higher on the wall and on surfaces that were previously dry. The freeze-thaw stress on a seawall cap, on tieback connections, and on rip-rap voids increases as ice accesses more of the structure. Lower-level years give the wall a winter to recover.
When do I need a permit for shoreline work?
Almost always. Michigan EGLE Part 325, Indiana DNR, Illinois IDNR, and Wisconsin DNR each regulate work below the ordinary high water mark. Federal jurisdiction under Army Corps Section 10 also attaches in most cases. Even minor repairs above the water line often need a notification or general permit. The right move is to engage a coastal engineer or seawall contractor before scoping the work, not after.
