Tall green trees and other plant life decorate the Arkansas and Louisiana landscapes. As rivers and other bodies of water weave through mountains and forests, holding back the desire to jump in and immerse yourself in your surroundings feels impossible. The Black River-Ouachita River connects these two lush states, flowing into Lake Ouachita. Once used for navigation, the river is part of a network of other tributaries that create the beauty of these southern states.
Before you dive into the tea-colored river, you need to know what’s waiting for you. Let’s discuss the Black River-Ouachita River’s many features to see if it’s safe for a swim.

- States that it connects: Arkansas and Louisiana

Where is the Black River-Ouachita River Located?
The start of the Ouachita is found in Arkansas’s Polk County. The southern-flowing river then moves through Jonesville (LA), meeting with Little River and Tensas. This convergence creates the Black River, which flows into the Red River in Jonesville. To navigate these waters, authorities established the Ouachita-Black Rivers Navigation Project in 1902, designing a waterway with 337 miles to travel.
Water Quality of the Black River-Ouachita River
One of the biggest complaints in this river is the high mercury content. Since the fish in certain sections absorb so much into their body, sourcing food from the river puts locals at risk. Local health officials even released a public statement in 2022, urging consumers not to eat more than 2 meals using fish from the river for their safety.
For anyone who wants to take a swim, swimming in a mercury-rich river isn’t a problem. Regardless of the recreational activity, there’s no danger to humans who just want to swim in the area. Many sources show that – apart from the mercury – the waters of this river offer excellent swimming, fishing, and boating opportunities.
Fish and Animals of the Black River-Ouachita River
Tons of wildlife live along the banks of the Black River-Ouachita River. Some areas are abundant with deer, turkeys, and bears, though these areas rarely see humans. As the local governments maintain their conservation efforts, alligators and bald eagles now inhabit more of the area. The plethora of fish in the Black River’s waters makes it a prime spot to catch something for dinner in moderation. Stay on alert for one of the local predators like alligators or bald eagles.
One of the most abundant fish in the river is the largemouth bass. Typically ranging from an olive-green hue to greenish gray, their dark blotches along their back make them easy to identify. No other bass gets as big as this catch, reaching up to 29.5 inches in length. According to current records, the heaviest one was just over 25 lbs.
The easiest place to spot these bass in the river is to look for the most vegetation along the riverbanks. They tend to be closer to lakes, sheltering them, they need to live up to 16 years. Their diet is primarily made up of other fish, and they have no aggression towards humans. Even if you swim by one, these fish are more concerned with their preferred diet.
The darkness of the Black River makes it the perfect spot for walleye fish. These fish prefer darker areas of the water, swimming beneath the shade as protection from the bright sun. They prefer to only feed with these needs met, so anyone who wants to fish for them will need the right timing. Plus, since they only like to be out when it’s sunny, any swimmer won’t see much of them.
Sometimes called yellow pike or yellow pickerel, this freshwater fish is more commonly seen in northern states. The species varies a lot in appearance in different bodies of water, but the Black River offers the right ambiance.
Western Ribbon Snakes
Louisiana’s rivers have tons of small fish and tadpoles, which is exactly why the western ribbon snake loves it. This snake is one of the most common in the Black River-Ouachita River, focusing on the aquatic wildlife for their meals. It is a type of garter snake, living natively in the United States, Mexico, and Central America.
With a slender black or brown body, these snakes reach up to 42 inches long. While these snakes seem fairly safe without any venom, their bodies are toxic to predators. Still, the strong bite of the western ribbon snake should be enough for anyone to keep their distance.
Within Louisiana’s borders, the Department of Wildlife and Fisheries estimates that the American alligator‘s population is 2 million. With numbers this high, it should be no surprise that they began repopulating the riverbanks recently as the environment improved. This reptile is the largest alligator species in North America, and they’ve been around for millions of years. While males weigh almost 1,000 pounds at 13 feet long, females usually reach 9 feet in length at 400+ lbs.
While local hunting laws allow locals to hunt the alligator, the steady population along the riverbanks makes them a big threat. No one wants to be in the wrong place at the wrong time, and the tannin-rich waters of the Black River conceal them well. Make sure to scan the area for any possible alligators before entering the water.
Many of the local white-tailed deer make an appearance along the river. In Louisiana, researchers show that there are almost 1 million white-tailed deer. Also known as the Virginia deer, this species forages in the nearby forests along the river to get their nutrients.
Since this deer sometimes acts as an opportunistic eater, their diet isn’t exclusively herbivorous. They sometimes eat small mice, songbirds, and similar small animals. Though humans aren’t on the menu, they are incredibly dangerous because of other inherent behaviors. They don’t directly go after humans unless provoked, but most of their dangers come from the many collisions they end up in each year.
