Water Temperature in Iowa City: General Trends and Swimming Opportunities

In Iowa City, Iowa, the Iowa River runs through the heart of the city, offering some opportunities for water-based activities. However, similar to other rivers in the area, swimming in the Iowa River is generally not recommended due to strong currents and water quality concerns. During the summer months, the river's water temperature can rise to around 70°F to 80°F (21°C to 27°C), which might seem inviting, but the water quality often fluctuates with rainfall and runoff from surrounding areas, affecting its safety for recreational swimming.

The Iowa River's flow can be swift, especially after storms or during spring runoff, making swimming dangerous in many areas. While there may be some calm spots where people might wade or cool off, the current risks and water quality are significant concerns. Additionally, pollution, including bacteria from agricultural runoff, can compromise the water's cleanliness and make it unsafe for contact recreation.

Though the Iowa River might not be ideal for swimming, Iowa City offers alternative ways to enjoy water activities. Local parks, lakes, and swimming pools provide safer options for swimming, including the popular Coralville Lake located just outside of Iowa City, which is known for its designated swimming areas. For those looking for a river experience, kayaking, canoeing, and fishing on the Iowa River are popular activities and can be enjoyed with proper safety precautions.
