The Des Moines River, which flows through Iowa and parts of southern Minnesota, experiences varying water temperatures depending on the season and location. During spring, as snow melts and rains feed the river, water temperatures tend to stay cool, often between 45°F and 60°F (7°C to 16°C). By summer, especially in the central and southern stretches of the river, water temperatures can rise to 70°F–80°F (21°C–27°C), providing a more comfortable environment for recreational activities like swimming and wading. However, the exact temperature can fluctuate based on recent weather, water flow, and the time of day.
Swimming in the Des Moines River is less common than in other recreational water bodies, mainly due to its strong currents, variable water levels, and occasional issues with water quality. While certain calm stretches may be suitable for wading or cooling off during the summer months, it’s crucial to exercise caution and follow local guidelines or advisories. Many people prefer engaging in other water-based activities like kayaking, fishing, or boating, which are popular along the river’s length, especially in areas with well-maintained access points and parks.
