Water Temperature in Stillwater River: General Trends and Swimming Opportunities

The Stillwater River, flowing through the mountainous regions of Montana, is known for its scenic beauty and clear, cool waters. The river’s water temperature is typically quite cold, especially in the upper sections where snowmelt from the surrounding mountains feeds into the river. During the summer months, the water temperature can range from 50 to 60°F (10 to 16°C), offering a refreshing but brisk environment for swimming. In the cooler months, temperatures can drop significantly, making swimming even less comfortable, especially in the more remote and high-altitude stretches of the river.

Swimming in the Stillwater River is possible but less common compared to other water activities like fishing, rafting, or kayaking. The river has several sections with calm waters suitable for wading or short swims, but due to the cold temperatures and fast-moving currents in certain areas, it is not typically a primary destination for swimming. However, in slower-moving stretches, particularly in the summer when the water levels are lower, it can be a nice place to cool off. As always, it’s important to be cautious of changing water conditions and potential hazards when swimming in natural rivers, especially in regions with significant mountain runoff.
