Flathead Valley Fishing Report for Week of March 18th 2024

March 20, 2024

As we edge into Spring, our mid-March fishing is looking good:

Ashley Lake

There’s a GREAT salmon bite on the west side of the lake, particularly in depths of 60-80 feet! Additionally, there’s a healthy population of perch found closer to the bottom, in the 20-40 foot range.

Bitterroot Lake

Anglers have reported catching large salmon, with some weighing up to 4 lbs. For those after rainbow trout, we recommend fishing in deeper waters of 180-250 feet towards the north end of the lake.

Middle Thompson

This spot is ideal for catching sizable salmon, with some reaching up to 16 inches, along with nice-sized perch and pike.

Upper Thompson

The perch are particularly active in the upper lobe, making it a hotspot for anglers.

Lake Mary Ronan

The perch are biting well in waters 30-35 feet deep, with occasional salmon catches at night.

Lower Stillwater

There’s great action here for both perch and pike with lots of ice.

Flathead Lake

Near the delta, in 20-40 feet of water, anglers using big whole fish as dead bait or large tubes are finding success.

Lake Koocanusa

The lake is fully accessible, with promising spots near the Rexford area or close to the dam. Trolling with PlugIt plugs or flies is highly recommended.

Swan Lake

There are good numbers of lake trout to be found, particularly near the southeast shore, with some weighing up to 10 lbs.

Dickey Lake

The salmon action is excellent here, with a few good-sized trout also in the mix.

Smith Lake

For those who prefer early morning fishing, Smith Lake is offering a good perch bite.

Blanchard Lake

While there are plenty of small crappie, anglers can also find a few nice-sized pike.

We hope this report helps you plan your next fishing adventure.

Happy fishing, and we look forward to seeing you on the water!
