The Red River, specifically the Red River of the South, is a massive river that runs through many states. The color red isn’t very appealing, especially when swimming. Is the Red River red? Can you swim in it? Follow along to discover what’s in the Red River and if it’s swimmable.

Some sections of the Red River are salty.

What is the Red River?

The Red River of the South is unique in the southern United States. Interestingly, it was once a tributary of the Mississippi River. However, it’s now a tributary of the Atchafalaya River. It’s 1,360 miles long and has a basin size of 65,595 square miles. This massive river goes through Louisiana, New Mexico, Texas, Oklahoma, and Arkansas. One of the best places to view the Red River is Palo Duro Canyon in Palo Duro Canyon State Park.

Interestingly, parts of the Red River are salty, especially tributaries above Lake Texoma. This is because there used to be an inland sea in the area and now what’s left are salt deposits. The Red River of the South acts as a natural boundary between Oklahoma and Texas. Although the River River is known for its reddish color, it’s not always red. However, it’s redder during flooding as the reddish color comes from the soil. This river has many tributaries and 2 bayous.

The Red River has been used for a long time by Native Americans, the Spanish, and early American settlers. Sometimes, it’s confused with the Red River of the North. But, that river is shorter, only stretching about 550 miles. This river was also the site of the Red River War. It was a war against indigenous Americans, to take their land and relocate them.

Can You Swim in the Red River?

If you’re thinking of swimming in the Red River of the south, take precautions and swim at your own risk. There are a few swimming holes in the river that are safe, but most of the river is harsh and winding. You can easily get swept away by its rushing waters. Sadly, there have been reports of people drowning in the Red River or falling in and never being found. Because of the rushing currents, it can be dangerous and hard to search. The floors are murky and the depth changes frequently without much warning. If you ever fall into a rushing river, try to remain calm. Panicking only worsens the situation and can tire out your muscles. Instead, follow the river’s flow as it can lead to a river bank.
