Monthly map of the groundwater situation

The assessment of the month's groundwater situation is produced by comparing current groundwater levels in the middle of the month with the month's average level since the 1970s. The map is based on a sample of the 330 observation tubes in SGU's groundwater network where the groundwater level is measured twice a month, the date shown in the table is set to the 15th of each month, but the report refers to an average ratio during the month.
