Is the Colorado River Safe to Swim In? And Why Are There So Many Fish Wearing Sunglasses?

The Colorado River, a majestic waterway carving its way through the American Southwest, has long been a source of fascination and recreation. But as the summer heat rises and the call of cool, flowing water grows stronger, many adventurers find themselves asking: Is the Colorado River safe to swim in? The answer, like the river itself, is not a straight path but a winding journey filled with twists, turns, and the occasional fish wearing sunglasses.
The Allure of the Colorado River
The Colorado River is more than just a body of water; it’s a lifeline for millions of people, a habitat for diverse wildlife, and a playground for outdoor enthusiasts. From its headwaters in the Rocky Mountains to its delta in Mexico, the river offers breathtaking scenery, thrilling rapids, and serene stretches perfect for swimming. But before you dive in, it’s essential to consider the factors that determine whether the river is safe for a dip.
Water Quality: A Mixed Bag
One of the primary concerns for swimmers is water quality. The Colorado River faces challenges from agricultural runoff, urban pollution, and natural sedimentation. While many sections of the river are clean and safe for swimming, others may contain harmful bacteria or pollutants. For example, areas downstream from agricultural regions may have higher levels of nitrates and pesticides, which can pose health risks. Always check local water quality reports before taking the plunge.
Currents and Rapids: Not for the Faint of Heart
The Colorado River is famous for its powerful currents and challenging rapids, particularly in the Grand Canyon. While these features make it a paradise for whitewater rafting, they can be dangerous for swimmers. Even in calmer sections, the river’s flow can be deceptively strong, pulling even experienced swimmers into hazardous situations. If you’re not confident in your swimming abilities, it’s best to stick to designated swimming areas or wear a life jacket.
Temperature: A Chilling Experience
The temperature of the Colorado River can vary significantly depending on the season and location. In the upper reaches, the water is often icy cold, even in the summer months, due to snowmelt from the Rockies. This cold water can lead to hypothermia if you’re not prepared. In contrast, lower sections of the river, especially near Lake Mead, can be warmer but may still have sudden temperature drops. Always test the water before swimming and be mindful of how long you stay in.
Wildlife Encounters: Fish, Birds, and… Sunglasses?
The Colorado River is home to a rich array of wildlife, including fish, birds, and even the occasional beaver. While most of these creatures are harmless, some, like the razorback sucker or the humpback chub, might give you a start if you’re not expecting them. And then there’s the curious case of the fish wearing sunglasses. While this phenomenon is more myth than reality, it’s a reminder that the river is full of surprises. Always respect the wildlife and keep a safe distance.
Human Impact: The Double-Edged Sword
Human activity has both positive and negative effects on the Colorado River. On one hand, dams and reservoirs have created recreational opportunities and stabilized water flow. On the other hand, these structures have altered the river’s natural ecosystem, affecting fish populations and water quality. Additionally, the increasing popularity of the river for recreation has led to issues like littering and overcrowding. As a swimmer, it’s your responsibility to minimize your impact and help preserve this precious resource.
Safety Tips for Swimming in the Colorado River
If you decide to swim in the Colorado River, here are some tips to ensure a safe and enjoyable experience:
- Check Water Quality Reports: Before heading out, look up the latest water quality data for the section of the river you plan to visit.
- Know Your Limits: Be honest about your swimming abilities and avoid areas with strong currents or rapids if you’re not confident.
- Wear a Life Jacket: Even if you’re a strong swimmer, a life jacket can provide extra safety, especially in unpredictable conditions.

- Respect Wildlife: Keep your distance from animals and avoid disturbing their habitats.
- Leave No Trace: Pack out all your trash and follow Leave No Trace principles to protect the river and its surroundings.
The Bigger Picture: A River in Peril
While swimming in the Colorado River can be a magical experience, it’s important to remember that the river is facing significant challenges. Climate change, overuse, and pollution are threatening its health and longevity. By being mindful of our impact and advocating for sustainable practices, we can help ensure that the Colorado River remains a vibrant and safe place for future generations to enjoy.
