Back in the 1830s, one of the most popular spots for covered wagons crossing the Mississippi River was just north of present-day Natchez. As many as 50 wagons a day would cross, carrying settlers bound for Texas. Many of them tired of the journey, and simply stopped on the Louisiana side and made that spot home.
Often this area was under water, and on one such occasion, Abner Smalley, one of the early settlers, stood high dry on a small strip of land waiting for a steamboat to make its usual landing for a refill of cordwood. The captain cried out to Mr. Smalley, "Well Abner, I see you're waterproof," and that's how the name of this town was born. Present-day Waterproof is two and a half miles from its original location, having moved three times to escape flood waters. This led to the construction of a huge levee which snakes around the town, upon which you can walk and drive for a close view of the river.
