Most of the time, getting checked by a conservation officer on the ice is a quick, polite interaction: show your license, talk about the bite, and get back to fishing. But when a person has a long track record of ignoring the rules, even a “simple” license check can turn into something far more serious.
That’s what happened in Macomb County, Michigan, where state officials said Derek Dermyer, 37, of Washington Township was sentenced to jail time after being caught ice fishing without a valid license on Lake St. Clair. Details were shared in the source post that pointed back to a report and a Michigan Department of Natural Resources press release.
A routine ice-fishing check ended with citations
According to the Michigan DNR, Dermyer was contacted by a DNR conservation officer in December while ice fishing on Lake St. Clair. He was cited for fishing without a license and for fishing while ineligible for licenses.
That second part is where things typically get serious. The DNR said Dermyer’s fishing license had been revoked until Jan. 1, meaning he wasn’t just short a piece of paperwork—he allegedly shouldn’t have been fishing at all during that period.
The history mattered as much as the day on the ice
Plenty of outdoorsmen have seen or lived the minor side of a license problem: a wallet left at home, an app that won’t load in the cold, or a guy who honestly thought his annual was still valid. Those situations usually get sorted out without anyone seeing the inside of a jail.
This one didn’t go that way because the state described Dermyer as someone with a history of “flouting the state’s hunting and fishing laws.” In other words, it wasn’t treated as a one-off mistake—it was treated like a pattern.
A judge handed down real time behind bars
Dermyer was sentenced March 10 to 30 to 180 days in jail, the Michigan DNR said. That’s a wide window, but either way it’s not the kind of outcome most anglers associate with a fishing license violation.
The DNR also made it clear this isn’t common. Lt. Todd Szyska, a Michigan DNR law enforcement supervisor, said in an email, “Although rare, violators are sentenced to jail in egregious cases, like this one.”
Why “rare” doesn’t mean “never” for license violations
Some folks hear “fishing without a license” and immediately think “fine” or “ticket.” And in a lot of first-time or truly accidental cases, that’s often the direction things go. But outdoors laws have teeth for a reason, especially when a person is already revoked or deemed ineligible.
From a boots-on-the-ground perspective, conservation officers aren’t just checking licenses to generate revenue. They’re managing pressure, enforcing limits, and protecting public resources that the rest of us pay into and play by the rules to enjoy. When someone keeps ignoring those rules, the system eventually starts stacking consequences that actually get their attention.
If you’re a law-abiding angler, the takeaway isn’t to worry that a missing license is going to land you in jail. The takeaway is simpler: know your status, and don’t fish when you’re not legal—especially if you’ve had prior run-ins.
Before you ever drill a hole, make sure your license is current and accessible. If your privileges have been revoked or suspended, don’t “test the waters” thinking it’s no big deal. That gamble can get expensive fast, and in extreme cases—like Michigan officials described here—it can turn into a stint in jail.
For most of us, the outdoors is the place we go to get away from problems, not create new ones. A valid license, a clear conscience, and a little respect for the rules go a long way—especially when a conservation officer walks up across the ice and asks to see what you’ve got.
