Tragic Day on Little Muskego Lake: 10-Year-Old Child Dies in Boating Accident Near Idle Isle Park
MUSKEGO, Wis. — A Saturday morning meant for sunshine, family, and fun on the water ended in unimaginable heartbreak when a 10-year-old child lost their life in a boating accident on Little Muskego Lake.
The tragic incident happened on June 7, 2025, just after 10 a.m., near the shores of Idle Isle Park — a beloved gathering spot for Muskego locals and visiting families alike. What began as a typical day on the lake became one that this community will never forget.
A Sudden, Shocking Loss
According to the Wisconsin Department of Natural Resources (DNR), a 74-year-old man was operating a boat on the lake when it collided with another vessel that was stationary at the time. That second boat had three people on board — including the 10-year-old child who was critically injured during the crash.
First responders from the Muskego Police Department and the Tess Corners Fire Department were on the scene quickly and did everything they could to save the child. Emergency care was given immediately at the park before the child was transported to a local hospital.
Sadly, the child passed away a short time later due to their injuries. No other major injuries were reported, but the emotional toll on all involved — including the other passengers and emergency responders — is significant.
A Community Shaken
For many in Muskego and surrounding areas, the lake is more than just a place to spend time — it’s part of the community’s rhythm during the summer. This tragedy has left many reeling and reflecting on how quickly joy can turn into grief.
“It makes me really sad. They were just trying to enjoy a day on the lake,” said Camila Gonzalez, a Milwaukee resident who frequently visits Idle Isle Park with her family. “It could’ve been any of us.”
James Bauer, visiting from Waukesha, echoed those thoughts. “It’s a scary reminder that even on the calmest day, the unexpected can happen. You hope it never does — especially not to a child.”
A Difficult but Important Conversation About Safety
This incident marks the fifth boating-related fatality in Wisconsin so far in 2025 — matching the number of fatalities at this time last year. Officials say this tragic event should be a wake-up call for boaters across the state to review safety protocols.
“Everyone needs to know the rules on the water — who has the right of way, how to handle different situations,” said Lt. Conservation Warden Drew Starch of the DNR. “The lake should be a place of peace and fun, but it’s also a place where things can go wrong fast.”
Starch added that boaters should always:
- Wear life jackets
- Avoid alcohol while boating
- Understand the navigation rules
- Keep distractions to a minimum
Boating education is also a key part of safety. Wisconsin law requires anyone born on or after January 1, 1989, to complete a certified boater safety course before operating a watercraft. Starch emphasized that these classes aren’t just about following rules — they’re about saving lives.
Investigation Ongoing, Questions Remain
At this time, officials are still investigating the cause of the crash. It is not yet clear what exactly led to the collision, and authorities have not commented on whether speed, visibility, or any other factors may have contributed.
The Wisconsin DNR is leading the investigation, with support from the Muskego Police Department. They are asking anyone who may have witnessed the accident or has relevant information to come forward.

Mourning a Life Cut Far Too Short
As of now, the identity of the child has not been publicly released, out of respect for the grieving family. What we do know is that a young life, filled with joy, promise, and innocence, was taken far too soon.
Idle Isle Park has turned somber since the accident. Flowers and handwritten notes now rest near the shoreline — silent, powerful tributes to the child whose life was lost.
For parents, neighbors, and visitors alike, it’s a hard moment to process. That child could’ve been anyone’s — a daughter, a son, a friend from school, or the smiling face on the boat next to yours. This is the kind of loss that doesn’t just hurt one family — it touches everyone.
A Call for Compassion and Caution
As the Muskego community mourns, there’s also a growing hope that this tragedy will inspire others to take boating safety more seriously than ever before.
“We can’t change what happened,” said one local resident quietly at the lake, “but we can learn from it. We can slow down, pay attention, and maybe — just maybe — save the next life.”
Whether you boat regularly or just once a summer, officials are urging everyone to double-check equipment, review safety rules, and have thoughtful conversations with kids and fellow passengers before heading out on the water.
Because sometimes, the smallest actions — a reminder to buckle a life vest, a pause to scan the lake — can make the biggest difference.
Our final Thoughts
What was meant to be a sunny, relaxing Saturday by the lake turned into a nightmare for one family — and a heartbreaking lesson for many more. The child who died at Little Muskego Lake will never be forgotten by the people who loved them or by a community that now carries the weight of this loss.
And as the summer continues, Muskego — and Wisconsin at large — is reminded that safety isn’t just about following rules. It’s about protecting each other, especially the youngest among us, every time we set out to enjoy the waters.
