Havre sits in the Hi-Line region of north-central Montana, and the fishing around it is almost entirely lake-based — four stillwater options that don't get the crowds you'd find near Glacier or the Missouri River corridor. Grassy Lake, Dry Lake, Lake Thibadeau, and Martin Lake are all within reasonable reach of town and offer the kind of low-pressure fishing that's increasingly hard to find in Montana. These are prairie lakes, which means the scenery is wide-open and wind-exposed rather than postcard-mountain, but the tradeoff is that you're often the only rig in the parking area. Expect warm-water and cold-water species depending on the lake and the time of year — this isn't designated wild trout or gold medal water, so manage expectations accordingly, but anglers who put in the time on these lakes consistently find fish. A small boat, kayak, or float tube opens up more water on all four lakes, though bank fishing is workable. If you're driving up from elsewhere in Montana specifically to fish, pair this with a stop at the Havre area's other public lands to make the trip worth the miles.
Frequently asked questions
What species can I expect to catch at these lakes near Havre?
The lakes around Havre — Grassy Lake, Dry Lake, Lake Thibadeau, and Martin Lake — are prairie stillwaters that typically hold species like perch, walleye, pike, and in some cases trout depending on stocking cycles. Check with Montana Fish, Wildlife and Parks for current species composition at each specific lake before you go, since stocking status and populations shift year to year.
When is the best time of year to fish these lakes?
Spring and early summer are generally the most productive windows on Hi-Line lakes, as water temperatures are still cool and fish are actively feeding after ice-out. Late summer can slow things down as surface temps rise, but early mornings and evenings remain your best bets. Ice fishing in winter is also a legitimate option on these lakes when conditions allow.
What time of day should I be on the water?
First light through mid-morning is consistently the most productive window on these prairie lakes, especially in warmer months when midday sun pushes fish deeper. Evening can also be solid, particularly for predatory species working the shallows. Wind picks up on the Hi-Line by afternoon most days, which can make boat control harder and fish less active near the surface.
Do I need a boat, or can I fish from shore?
Bank fishing is possible at all four lakes, but a small boat, kayak, or float tube will meaningfully expand your options by letting you reach deeper structure and cover more water. If you're fishing from shore, focus on points, inlets, and any visible weed edges where fish tend to concentrate.
What license and regulations do I need?
You'll need a valid Montana fishing license, available online through Montana Fish, Wildlife and Parks or at local sporting goods retailers in Havre. Regulations vary by water body and can include specific size or bag limits, so pull up the current FWP regulations for Hill County before your trip rather than assuming standard statewide rules apply across all four lakes.
