The Red River is a big river. It is in the south. The water looks red. It flows through many states. It is very long. 
The Red River is in the southern United States. It gets its name from its red water. This color comes from the red land nearby.
The river flows through many states. It acts as a border for Texas and Oklahoma.
Some parts of the river are salty. This happens because of salt in the ground. The salt flows into the water every day.
In the past, many fallen trees blocked the way. These trees made a big jam. People had to clear them to move boats. 
Now, the river flows into the Atchafalaya River. From there, it goes to the sea. It is a very busy place for nature.
The Red River is in the southern United States. It has reddish water. This color comes from the red land it passes through. This river is different from the Red River of the North. 
The Red River starts in the Texas panhandle. It flows east and marks the border between Texas and Oklahoma. It also forms a short border for Texas and Arkansas. Later, it flows into Louisiana. 
Some parts of the river are salty. Salt from the ground leaks into the water. This can add 3,450 tons of salt every day. 
In the past, the river was hard to use. A large jam of fallen trees blocked the way. People called this the Great Raft. It took many years to clear the logs. Now, many boats can travel on the water. The river flows through flat lands and big marshes. It is a very important part of the land.
The Red River is a major river in the Southern United States. It gets its name from the reddish color of its water. This happens because the river flows through red-bed country in its watershed. It is often called the Red River of the South. This helps people tell it apart from the Red River of the North. That other river flows near Minnesota and North Dakota into Canada. 
The river begins in two branches in the Texas panhandle. One branch starts where Buck Creek and Prairie Dog Town Fork meet. 
Many people have explored this river over a long time. In 1806, President Thomas Jefferson sent an expedition to see the new lands. He thought the river was very interesting. In 1852, Randolph B. Marcy led another expedition to find the river's sources. Later, in 1815, Captain Henry Miller Shreve brought the first steamboat up the river. 
There are many interesting facts about the water and the land. The river is actually salty in some parts above Lake Texoma. 
Today, the river connects many different places and people. Large cities like Shreveport and Bossier City grew on its banks. 
The Red River is a major river system in the Southern United States. It is frequently called the Red River of the South. This name helps distinguish it from the Red River of the North. That northern river flows between Minnesota and North Dakota into Manitoba, Canada. The Red River gets its name from its reddish water color. This color comes from the river passing through red-bed country within its watershed. The river is a vital part of the southern Great Plains. Its drainage basin, or watershed, covers 230,000 square miles. This basin includes parts of Texas, Oklahoma, New Mexico, Arkansas, and Louisiana.
The river begins in two main branches in the Texas panhandle. One branch starts at the junction of Buck Creek and the Prairie Dog Town Fork in Harmon County, Oklahoma. Specialists have debated whether the North Fork or the Prairie Dog Town Fork is the true stem. Today, the southern Prairie Dog Town Fork is considered the main stem. It is about 150 miles long and forms in Randall County, Texas. It begins where Tierra Blanca Creek meets the intermittent Palo Duro Creek. 
The river follows a winding path through many different environments. It flows east and serves as a border between Texas and Oklahoma. It also forms a short border between Texas and Arkansas. 

There is a unique chemical process occurring in the upper parts of the river. The water is salty in the tributaries located above Lake Texoma. This saltiness is caused by Permian salt deposits, which are mostly sodium chloride. These deposits were buried long ago by deposition. However, the salt continues to leach through natural seeps in the ground. This process sends as much as 3,450 tons of salt into the Red River every day. 
Human history is closely tied to the Red River. Before European contact, diverse Native American cultures lived along its banks. The Lipan Apache lived in the west until the 18th century. Then, the Comanche moved in from the north. The Wichita and Tonkawa people lived in the prairie middle sections. In the eastern Piney Woods, the Caddo Confederacy lived near the lower river. In 1806, President Thomas Jefferson sent an expedition to explore the area. He called the river one of the most interesting waters in the region. In 1852, Randolph B. Marcy led an expedition to find the river's sources. Later, in 1815, Captain Henry Miller Shreve brought the first steamboat up the river. This event helped end monopolies on river navigation in the United States.
The river has also been a site of political and military importance. The south bank once formed part of the US–Mexico border. This was defined by the Adams–Onís Treaty of 1819. The boundary changed after the Texas Annexation and the Treaty of Guadalupe Hidalgo. During the American Civil War, the Red River Campaign took place in Louisiana. This was a failed attempt by the Union to occupy eastern Texas. In 1931, a conflict called the "Toll Bridge War" occurred between Oklahoma and Texas. This was a dispute over a bridge crossing the Red River.
Today, the river supports many communities and industries. Large cities like Shreveport and Bossier City developed on its banks.
