The Mississippi River is a very big river. 

The river has three main parts. The Upper Mississippi starts at the lake. It has 43 dams to help boats move. Saint Anthony Falls is the only true waterfall here. The Middle Mississippi flows from St. Louis to Cairo. The Lower Mississippi flows from Cairo to the sea.
Many people have lived here for a long time. Native Americans lived along the river for thousands of years. Later, people used steamboats to move goods. Today, large barges carry items on the water. The river is so big that people call it "The Mighty Mississippi."
The Mississippi River is a huge and important waterway in North America. It is the second-longest river in the United States. The river starts at Lake Itasca in northern Minnesota. From there, it flows south for 2,340 miles. It eventually ends at the Mississippi River Delta in the Gulf of Mexico. 
Scientists divide the river into three main sections. The Upper Mississippi begins at the lake and goes to St. Louis, Missouri. It uses 43 dams to help boats travel. One special spot is Saint Anthony Falls. This is the only true waterfall on the entire river. 

People have lived near this river for thousands of years. Native Americans lived along the banks for a very long time. Some groups were hunters, while others were farmers. They even practiced aquaculture, which is a way of farming in water. 
This river covers a massive area called a drainage basin. This basin is 1,151,000 square miles in size. It drains parts of 32 U.S. states and two Canadian provinces. 

Today, the river is still a very busy place. Large ships and barges carry many items across the water. 
The Mississippi River is a massive waterway in North America. It is the second-longest river in the United States. The Missouri River is actually longer. The Mississippi flows for 2,340 miles. It begins at Lake Itasca in northern Minnesota. It ends at the Mississippi River Delta in the Gulf of Mexico. 
The river's name comes from the French rendering of an Anishinaabe name. The word Misi-ziibi means "Great River." 
Scientists divide the river into three distinct sections. The Upper Mississippi runs from Lake Itasca to St. Louis, Missouri. The Middle Mississippi flows from St. Louis to Cairo, Illinois. The Lower Mississippi flows from Cairo to the Gulf of Mexico. 
The Upper Mississippi is heavily managed by humans. There are 43 dams in this section. Fourteen dams are above Minneapolis for power and recreation. The other 29 dams contain locks to help commercial boats. 
The Middle Mississippi section is 190 miles long. It falls 220 feet between St. Louis and Cairo. It is mostly free-flowing with few major tributaries. The main tributaries are the Missouri and Meramec rivers. The Lower Mississippi is much larger in volume. At the confluence with the Ohio River, the Ohio actually carries more water. 
The Mississippi River has a massive drainage basin. A drainage basin is a watershed area that collects water. This basin covers 1,151,000 square miles. It drains parts of 32 U.S. states and two Canadian provinces. 
Despite its importance, the river faces environmental challenges. Since the 20th century, pollution has become a major issue. Agricultural runoff is a primary cause. This runoff contains high levels of nutrients and chemicals. These substances flow into the Gulf of Mexico. This process contributes to a "dead zone" in the Gulf. This is an area where oxygen levels are too low for most life. Managing the river's health remains a complex task for many people.
