Question

If you answered thank alot!

Answer 1

I am going to say the Ohio River...

The Ohio River supplies nearly half of the Mississippi's flow, and from Cairo to New Orleans the river is generally 1,000 to 1,600 m (3,000 to 5,000 ft) wide with a navigation channel 3 to 4 m (9 to 12 ft) deep. In this lower course, the river meanders through a floodplain that is 60 to 110 km (40 to 70 mi) wide. Roughly 300 km (200 mi) before it reaches the Gulf of Mexico, the river separates into two branches. At the Old River Diversion, a system of dams, locks, and levees sends about one-quarter of the Mississippi's flow to the gulf via the Atchafalaya River. The remainder flows past Baton Rouge and New Orleans before branching in the river's delta into smaller channels, known as distributaries, which enter the gulf.

The MISSOURI RIVER, draining the Great Plains to the west, joins the Mississippi at Saint Louis. It is the longest tributary, and constitutes more than 40% of the Mississippi system drainage area, while furnishing about 20% of the total discharge. At Cairo, Ill., the Mississippi is joined from the east by the OHIO RIVER.

So while the Missouri is the longest it is the Ohio that has the most volume.

Yes. Most rivers that don't drain into the oceans drains into the Mississippi. That is most between the Rockies and the Appalachians. Guess that could be a bit too broad a statement, as a some Southern Rivers drain into the Gulf of Mexico.

Answer 3

Yes indeed. The Rock River that I live on flows directly into the mighty Mississippi at the Quad Cities.
