The Bighorn River, spanning Wyoming and Montana, is a prominent waterway known for its striking landscapes and abundant fishing opportunities. The river's water temperature is influenced by its source in the Bighorn Mountains and the regulated flows from reservoirs like the Yellowtail Dam. In summer, temperatures in the river's upper stretches often range from the mid-50s to mid-60s Fahrenheit (12-18°C), while lower sections warmed by the sun can occasionally reach the 70s (21-24°C). During winter, the water temperature drops significantly, especially in unregulated sections, often hovering near freezing.

Swimming in the Bighorn River is possible but not a primary activity due to the river's flow characteristics and recreational focus. Many sections of the river are fast-moving, with varying depths and a cold current that may not be comfortable for extended swimming. The river is much more popular for fly fishing, as it is renowned for its trout populations, and for rafting and kayaking, which take advantage of its scenic canyons and steady flows.

For those looking to cool off, there are calmer stretches along the riverbanks where wading or a quick dip might be enjoyable in summer. However, swimming enthusiasts often prefer nearby lakes or reservoirs like Bighorn Lake, which offer warmer and more tranquil waters. The Bighorn River remains a destination for those seeking adventure and natural beauty, with activities like boating and fishing taking center stage.
