high-water marks
Maximum recorded levels
High-water marks are the highest levels reached by water—the line left on a beach after peak tide, or the stain on a basement wall after flooding recedes.
Figuratively, a high-water mark is a peak achievement or maximum extent: The 1960s represented the high-water mark of American liberalism.
The singular form is more common for the figurative sense.
