Esshup I agree with your idea that too narrow of slot will eventually just become a half depth dip in the bottom.
The slots I transverse the plateau in my pond were made with a scraper with either an eight or ten foot cut (cant remember right now). They ranged in depth but the deepest probably 3' deep. They have sloughed off considerably. They are wide enough that the slot is still there, but if they were only the width of a backhoe bucket, they would just be an almost unnoticeable line in the bottom. And our clay holds up pretty well. But any sediment will always seek the lowest spot if it can get there.
