Operational hydrology network information (before data reliability is assessed). Official information can be obtained from the Hydrological Observations Department of LHMT.
The water level is indicated in cm above the zero of the water measuring station (VMS) schedule (the zero of the VMS schedule is a conditional horizontal plane from which the water level is deducted. It is set about 0.5 m below the lowest possible water level).
