How did Will get the word out to the rivermen? I just don't think that telling the Cincinnati Enquirer would be sufficient.

Warning was issued to rivermen yesterday by Major W. P. Stokey, Engineer in Charge of the Cincinnati District, Corps of Engineers, to beware of Ohio River Dams Numbers 17, 18 and 21. The rise of the river was so rapid at these points that the wickets could not be lowered and navigators are advised not to attempt operation of boats past the dams without knowledge that the stage of the water is sufficiently high to permit clearance. The wickets will be lowered as soon as the river recedes.

The rise of the river was so rapid at these points that the wickets could not be lowered
Here's what Wikipedia says about wickets in dams, and in particular about wickets in dams on the Ohio River:
A wicket dam, Chanoine wicket movable dam, or barrage à hausse mobile is a movable barrier across the width of a river that is used to hold up water and allow navigation under low-water conditions. When the wickets are lowered during high-water conditions, the river flow is unimpeded. A navigation lock is usually constructed alongside the wicket dam. The wicket dam was invented in the 19th century by Jacques Henri Chanoine [fr], an engineer in the French Corps des ponts et chaussées [fr].
Construction of wicket dams primarily occurred in the late 19th and early 20th centuries. William Price Craighill completed the first of the moveable wicket dams built in the United States, after visiting France to study their use. A Chanoine wicket movable dam was constructed by William Emery Merrill at Davis's Island, 5½ miles below Pittsburgh. From 1875 until the turn of the century, the United States Army Corps of Engineers constructed a series of 53 wicket dams to canalize the Ohio River to meet the demands of year-round navigation. In the 1950s, the Corps undertook the Ohio River Navigation Modernization Program to replace the obsolete system of wicket dams and small locks.
So I guess that when the wicket is raised, it creates a sort of a lock, but the setup is not as solid as the lock systems on the Mississippi River and on the Panama Canal. I guess.
