Official measuring station · 2093What does the level mean?
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.
Is the water level normal?
That depends on the lake and season. The official station shows annual trends and long-term reference values. We do not infer a flood warning or navigability from a single reading.
