The level is the elevation of the water surface above sea level, not the water depth. When it falls, the same location becomes shallower. Clearance under a boat also depends on the lakebed and the boat’s draught.
Uncorrected live readings · usually delayed by 9–19 minutes. Compared with the same station about one hour earlier.
