Brush Lake is a deep, clear lake with beaches surrounded by grass fields and spring wheat.
This mile long lake offers public access for swimming and is ideal for wildlife viewing, motorized boating and water skiing.
The Northeast portion of the lake includes a day use area with a boat ramp, dock and picnic area, along with a 12-site campground which consists of (10) electric campsites and (2) double campsite with electricity.
Due to the high alkali content of it's crystal clear waters, Brush Lake does not support any significant fish life.

Aquatic Invasive Species
Help protect Montana's waters
AIS can be easily spread from one waterbody to the other. Anglers, boaters, construction workers, pond owners, gardeners, seaplane pilots, field workers - virtually anyone who works or plays in or around water can unknowingly transport these pests on their boats and equipment. It takes only one mistake to potentially infest a new water body.
