The Mississippi River is the second longest river in the United States, after the Missouri River. Its drainage basin covers most of the Midwestern United States and parts of the southern United States. It also forms part of the boundary between the United States and Canada. The Mississippi River has many tributaries, but the longest is the Ohio River.<\/p>\n

The Ohio River is the longest tributary of the Mississippi River. It is formed by the confluence of the Allegheny River, which flows from Pennsylvania, and the Monongahela River, which flows from West Virginia. The Ohio River is approximately 981 miles (1,579 kilometers) long and is the second longest tributary of the Mississippi River, after the Missouri River. It is also the second largest river in the United States, behind only the Mississippi.<\/p>\n

The Ohio River is an important transportation route and is used by barge traffic, fishing boats, and pleasure craft. It also serves as an important source of drinking water for the many cities and towns that line its banks. In addition, the Ohio River’s vast freshwater reserves are used to provide power for industry along the river and in its valleys.<\/p>\n

The Ohio River is home to numerous plants and animals, including some that are listed as threatened or endangered. Fish species such as American shad, carp, smallmouth bass, and walleye can all be found in the Ohio River. In addition, the river supports a wide variety of birds, amphibians, reptiles, and mammals. The river is also home to hundreds of species of insects, including the caddisfly, mayfly, stonefly, and dragonfly.<\/p>\n
