Louisville is a seaport, of sorts. The Louisville, Kentucky, “seacoast” is the waterfront along the Ohio River, with that other coastal state, Indiana, just across the water. Barge traffic has moved up and down the river for a couple of centuries, winding its watery way to the Gulf of Mexico.
Most of the waterfront is industrial, or devoted to roads. There are a couple of parks. And a boat ramp, where this sign was found:
Less whimsical is this concrete obelisk, marked off in feet, showing the height of the river above “normal” elevation. At 26.5 feet is a note that this was the height of the 1997 flood. A mark at 29.2 feet shows the 1964 flood level. A mark at 30.1 feet shows the 1945 flood level. And the red arrow at the top points to the air above the 32 foot mark, noting the 1937 flood level, at 40 feet, would be somewhere up there.
