Brush Lake State Park

Brush Lake State Park is the only state park in the northeast corner of Montana.

Brush Lake is a deep lake (65 feet) in a closed basin and the site of National Science Foundation research on climate change. The lake boasts 45 feet of sediments showcasing 10,000 years of pollen and mineral depositing helping to tell the story of climate, and its changes, since the Ice Age.

Looking to camp?

Brush Lake State Park is 280-acres and its water quality is theorized to be more ocean-like than freshwater like - making it an ideal swimming location in the summer months. Both deep and incredibly clear, Brush Lake’s beaches are surrounded by grass fields and spring wheat during the summer.

Due to its close proximity to Canada, during Prohibition liquor was easy to come by and kept the Brush Lake Summer Resort in business. There was also a dance hall! After the Prohibition era, church and scout groups used the lake, but in the years before it became a state park, Brush Lake wasn’t the popular destination it once had been. Today the area where the dance hall once stood on the south side of the lake, is now privately held.

In Eastern Montana, it is not uncommon to see the Aurora Borealis during solar events, especially during the fall and winter. Brush Lake's northern latitude and remote location make it a "stellar" destination for your next stargazing or northern lights viewing adventure. As a dark sky location, Brush Lake is guaranteed to bring some of the best night sky views in the area.

Because of the high alkali content, Brush Lake does not support a significant fish population. But in contrast, it showcases a distinctive aquamarine blue color. The lake attracts many varieties of birds including various species of ducks, gulls, and many others. Brush Lake has become a great location for bird watchers worldwide.
