Waterways Used by Ohio & Mississippi Valley Settlers to Ship Goods South

Primary Route

Settlers used the Ohio River → Mississippi River corridor as the main southbound highway for flatboats, keelboats, and later steamboats.

How It Worked

1. Farmers in Ohio, Kentucky, Indiana, Illinois loaded flatboats (broadhorns) with corn, wheat, whiskey, pork, tobacco.
2. Drifted downstream with current (no upstream return – boats sold for lumber at destination).
3. Entered Mississippi River at Cairo, IL (confluence).
4. Continued to Natchez, New Orleans – major export entrepôts.

Resulting River Towns

• Ohio River: Pittsburgh, Wheeling, Marietta, Cincinnati, Louisville, Evansville.
• Mississippi River: Cairo, Memphis, Vicksburg, Natchez, New Orleans.

Keelboats & Steamboats (Post-1811)

• Keelboats: poled/sailed upstream (slow, expensive).
• Steamboats (Fulton's New Orleans, 1811): two-way trade; cities boomed.

Strategic Impact

This waterway tied the trans-Appalachian West to Gulf/Atlantic markets, enabling the economic integration that made the Erie Canal and later railroads viable.
