Is Clear Lake full?

Clear Lake is a natural glacial lake, so it has no full pool. A low weir at its outlet keeps it from draining below a set point, but nothing holds it at a fixed top level; the page compares the level with past years. It is 0.20 ft higher than a year ago (1,226.82 ft on Nov 9, 2025).
