Some lakes have no season variation.
Some lakes/rivers/wetlands have a water level of 0 for many years. Zero,
absolutely no water.
The water is usually mapped as the maximum water level.
Exceptions? Flood levels are not mapped, so if the maximum water level
of a river is when it is in flood then that level is not mapped.
Rivers have simply been mapped in some parts of my location without
river banks, as those cannot really be determined.
For salt lakes - the extent of the salt is a fair marker for the maximum
