Ohio River

The Ohio River is one of the longest rivers in the United States with a length of 1575 km. It begins in Pittsburgh, where the Allegheny and Monongahela Rivers converge, then runs through or borders five more states: Ohio, West Virginia, Indiana, Kentucky, and ultimately Illinois, where it meets the Mississippi. There are at least 20 dams along the river, which assist to service the more than five million people that rely on it for drinking water.

Though the precise order and lengths of these rivers have been questioned (differences typically originate from where the official start is located, or whether or not specific tributaries are included), one thing is obvious: the United States has a wealth of enormous, lengthy, and beautiful rivers. These significant water sources, each distinct in their own right, serve as drinking water, energy suppliers, and irrigation supplies for most of the United States, running from the northernmost corner to the southernmost state and crisscrossing the country.

The Ohio River is a climatic transition zone because its water flows along the outskirts of humid subtropical and humid continental climate zones. It is home to species and plants from both climates. It frequently freezes over around Pittsburgh during the winter, but very infrequently further south toward Cincinnati and Louisville. It is ice-free all year in areas like Paducah, Kentucky, and Owensboro, Kentucky in the South near the Ohio River's confluence with the Mississippi.
