Water dam, soil dam

The dam of water, the dam of soil, shows that Hamoon Lake has been drying up since the late thirties. Sometimes it is full of water and sometimes it is short of water. In the last two years, the drought has intensified and now Lake Hamoon is completely dry.
Since the 1930s, a group of people from Sistan migrated to Golestan and Mazandaran provinces due to drought, and the migration process is still going on.ر
