Rivers are unique and vital waterways that offer various activities for the outdoor enthusiast. They’re also vital ecosystems and waterways that significantly contribute to human infrastructure and development.
Hydroelectric power is a huge resource for most communities, and it wouldn’t be possible without rivers. Drinking water, wastewater removal, and agriculture are just a few of the other things that waterways like rivers support.
Whether you’re in search of scenery, swimming, or kayaking, the United States delivers a lot of great recreational spots for people to enjoy. One of the most gorgeous sights on this planet is looking through a body of water.
When a normal body of water is murky, you look at the water. When the water is crystal clear, you look through it straight to the bottom and see all the things in between.
So, what if you have a love of rivers and a love of clear water? Where can you find both? What are 6 of the clearest rivers in the United States?
1. San Marcos River in Texas
Not only is this water clear, but it is also extraordinarily clean. It is ten times cleaner than the FDA drinking water requirements. This is because the San Marcos River is fed by freshwater springs near the city of San Marcos.
The water is constantly 72 degrees, so recreation at varying spots along the river is popular. There are parts of the clear water that are rapids while others are lazy. It offers a bit of choice for everyone, from tubing to white water kayaking.
Eight endangered animals live here, including the fountain darter and the Texas blind salamander. It has one of the most diverse ecosystems in the American southwest. It is dealing with an invasive species issue, with 48 documented species having been introduced to the area.
2. The Mad River in Vermont
Warren Falls is one of the highlights of the Mad River in Vermont. The Mad River also contains first-class water pools and other great recreational spots along its banks.
The water is almost crystal clear but has an emerald twinge to it. That doesn’t stop visitors from being able to see to the bottom. There are brook trout, brown trout, and rainbow trout to be fished from the waters of the Mad River.
The Mad River is a tributary of the Winooski River, which eventually flows into Lake Champlain.
3. Guadalupe River in Texas
The Guadalupe River is in central Texas. There are several dams along this river. The upper part of the river in the hill country is where it is crystal clear. The water is swifter near its origin, and the bottom is made of limestone, which means there’s hardly any sediment. An aquifer called Edwards Aquifer feeds all the channels that merge with this river.
The lack of sediment and spring-filled water makes for a crystal-clear environment. It is home to the Guadalupe round-nose minnow. About a mile southwest of the river, a rare white-nosed coati has been spotted.
4. Black River in Missouri
There are pools located along the east fork of the Black River in Johnson’s Shut-Ins State Park that are famous for being crystal clear and fun. The Upper Black River before Clearwater Lake is clean and clear as well.
The Black River is part of the Ozark River system, fed by fresh springs. The river’s stone encasement keeps it free from sediments. The three forks diverge in the Mark Twain National Forest and come back together in Arkansas.
The pools on the east fork of the Black River are technically still part of the river, but the water gets trapped in the ancient worn nooks and crannies of rocks along the banks. These rocks and barriers form sloping falls and slowly moving pools of water that are some of the clearest in the United States.
Recreational watersports on the east fork of the Black River begin below these pools because the river is not navigable through the pool area.
This river is home to wildlife, including eastern spiny softshell turtles, longnose gar, crayfish, red ear slider turtles, map turtles, and bullfrogs. Smallmouth bass is a popular catch for fishermen.
5. Comal River in Texas
This river is only two miles long, and its entire length is within the city of New Braunfels. It has a rocky bottom which helps make it one of the clearest rivers in the United States.
The Comal River meets up with the Guadalupe River, but it is distinctly different. It is one of the tributaries that are fed by the Edwards Aquifer into the Guadalupe. The name of the spring feeding the Edwards Aquifer is the Comal Springs. It is considered a river because it is fully navigable, and the locals of New Braunfels hold this river in high esteem.
The fountain darter lives here, and it is only one of two home locations left in the wild for this fish. The other is the San Marcos River, which we’ve already explored on our list of 6 clearest rivers.
6. Smith River in California
The Smith River’s origins are in the Klamath Mountains. It then makes its way through Del Norte County in Northern California before meeting the Pacific. This is California’s only undammed river. It is environmentally protected in various ways, and almost no human development has been allowed. Salmon and steelhead are found in abundance.
The surrounding forest is an old forest that hasn’t been damaged by human industry. There are huge redwoods to be seen on the Smith River. The water has remained almost crystal clear because of this and the surrounding geology.
Almost no sediment exists in this river. There are green and blue stones along the river bottom that shine in the right sunlight through the clear water. This makes the water turquoise.
