Minnesota’s Lake Alice Drains in Days After Valve Failure, Leaving Dead Fish Behind

In the “Land of 10,000 Lakes,” the count just slipped, at least for now.
Lake Alice, a 26-acre pocket of water tucked into Minnesota’s eastern edge, has all but vanished. Where ripples once carried bluegill and bass, there’s now only a thin trickle, the cracked lakebed glinting under the August sun.

Scattered across it: a grim scatter of fish that never made the escape.

For one local, the disappearance didn’t register at first. Out for a Sunday stroll with a dog through William O’Brien State Park, they expected the same familiar view. Instead, they found themselves walking directly across the lakebed. “I walked into the lake bed … because how many times will you get to do that?” they said, still shaken. The place they’d known all their life was suddenly gone.

A valve that wouldn’t close

Minnesota’s Department of Natural Resources (DNR) says the unraveling started with the lake’s water control system, a concrete structure designed to feed the St. Croix River while keeping Lake Alice’s levels in check.

Last month, staff opened the lake’s valve to ease overflow after water began pressing against its dike, the earthen wall meant to hold floods at bay. The release worked, until it didn’t. When the valve was opened again last Friday to lower another spike in water levels, the mechanism jammed wide open. By the next day, Lake Alice was spilling itself into the St. Croix without restraint.

In less than a week, nine feet of water was reduced to scattered puddles, matted algae and wet sand replacing the reflective expanse. The fish that stocked the lake so well yellow perch, largemouth bass, bluegill didn’t stand much of a chance.

A community trying to save what’s left

Some residents couldn’t just watch. Over the weekend, a few made small-scale rescue attempts, scooping the surviving fish from shrinking pools and ferrying them to the St. Croix River. It was a race against the sun and oxygen depletion.

One resident described seeing the last holdouts, fish twisting and thrashing in shallow water, their survival clock ticking fast. “To see that there’s 26 acres of animals just dying around you and there’s nothing for you to do about it was sobering,” they said.

For a fisheries researcher, scenes like this hit on multiple levels. It’s not only the loss of the fish themselves, but the abrupt collapse of the ecosystem from the plankton in the water column to the predators that worked its edges. It’s weeks or months of recovery for the waterbody, and years before its fishery could return to form.

No quick refill

The DNR estimates that Lake Alice’s water levels will stay low for four to six weeks while crews repair the faulty valve. Until then, the lake will remain closed to water-based activities like swimming, canoeing, and fishing.

Visitors to the park can still walk the perimeter path, but the draw isn’t what it used to be. The smell of decaying fish now greets those who come too close, something one local noticed before even reaching the shore. “I smell dead fish,” was the first thought after stepping from the car.

The ripple beyond the shore

This time of year, Lake Alice usually pulls in swimmers, anglers, and picnickers eager for its calm waters. Now, the St. Croix River, unaffected by the lake’s draining is the nearest alternative for summer recreation. While that’s a convenient option for visitors, it’s no replacement for the unique character Lake Alice offered.

Incidents like this also serve as a stark reminder that even small, routine adjustments to water control structures can carry huge consequences. The balance between preventing floods and preserving a lake’s ecosystem is delicate, something aquarists understand well when managing even a few gallons in a tank. In the case of Lake Alice, that balance tipped overnight.

For now, the “Land of 10,000 Lakes” lives on with 9,999, waiting for one of its smaller gems to return. Whether its fishery will bounce back quickly depends on stocking efforts, water quality recovery, and how fast aquatic vegetation reclaims the lakebed. Nature is resilient, but it’s rarely on a human schedule.

Until the repairs are done, Lake Alice is less a destination and more a lesson, a reminder of how connected mechanics and biology truly are. One stuck valve was all it took to drain decades of life from a basin, leaving behind a shoreline of silence.
