The Archivist could name what set the Okeechobee flood apart from the earlier entries.
The Galveston surge arrived at a shoreline in daylight — the first water came on a Saturday afternoon, and by the time darkness fell the worst of the surge had already passed and those who had survived were surviving in a defined landscape of damaged structures and known streets, the devastation visible even if the scale of it was not yet comprehended. The Miami storm struck in the early morning hours, its surge arriving before dawn, but the geometry of a coastal barrier island gave survivors a fixed reference: the ocean was east, the bay was west, the causeway was north. The landscape had an orientation.
The south shore of Lake Okeechobee in the night of September 16th had no orientation.

The muck plain was flat in every direction for miles.
There were no landmarks above the water level because there was nothing in the landscape above the water level. The trees that existed — the occasional cypress, the live oaks near the older farmhouses — had been stripped of their canopy by the wind and their profiles in the darkness were indistinguishable from any other vertical obstruction in a landscape where every vertical obstruction was reduced to the same silhouette against the sky, which was not visible because the sky was rain and cloud and darkness.
A person in two feet of black water on the south shore muck plain at midnight on September 16th could not determine which direction was which. The wind was from the northeast — that was directional information — but the wind was also blowing rain horizontally in all directions as it interacted with the structures and their remains, and the sound of the wind was the same in every direction. The water beneath their feet was black and opaque and gave no reflection. The ground it covered was the same in every direction: flat muck, irrigation ditch, flat muck.
To move through this landscape was to move without reference.

The Archivist had no precise prior entry for a flood like this in total darkness on flat agricultural ground.
The prior coastal entries had involved populated shores where the survivors, after the surge receded, were in a landscape that was damaged and disoriented but fundamentally recognizable as the landscape they had been in before. The streets were still streets. The lots were still lots. The orientation of the shore to the sea was unchanged. What had been destroyed had been destroyed in a place that could be identified and returned to.
The south shore muck plain, after the lake had moved through it, would also be identifiable and returnable. But in the night of the flood it was neither. It was an undifferentiated surface of black water and black mud and darkness, without fixed points of reference, in which the difference between a drainage ditch and open ground was the difference between three feet of water and two — not distinguishable by any sense available to a person moving through it in the dark.

People survived the Okeechobee flood by finding things that were higher than the water.
The things that were higher than the water were whatever structural elements remained attached to the ground at an elevation above the flood surface: the second floors of the multi-story structures, the roofs of the single-story structures that had not lost their roofs, the taller trees that had not been stripped to the point of being unclimbable, the elevated road beds of the county roads where they crossed low points on fills that sat a few feet above the general terrain.
Finding these things in the dark, through black water of unknown depth, in a wind that was still at hurricane force as the storm continued its northwest track, required the specific knowledge of having been in this exact landscape before the water arrived — knowing which road was in which direction, which field ran to the higher ground, which farm’s outbuilding was on a fill that sat slightly above the rest.
The people who had that knowledge were the people who had been here for years. Some survived by it.
The people who did not have that knowledge — who had arrived for the harvest season, who had come from Georgia and Alabama, who had been on the south shore for weeks or months rather than years — moved through the landscape the way people move through unknown country in the dark in a flood, which is to say they moved toward whatever they could see or hear or feel that seemed higher or more solid than where they were, and some of them found it and some of them did not.
The Archivist kept both outcomes: the people who knew enough of the ground to find height, and the people who moved blind through it.
