The lagoon, called Hurolazim, has been considered a major cause for the dust storm that swept Khuzestan Province.
Speaking at a press conference in Khuzestan capital Ahvaz, Masoumeh Ebtekar said that "One of the causes for dust storms in the country is the drought that has caused lagoons to dry out.
She also note that drilling at Hurolazim Lagoon to extract oil and the construction of the Gotvand Dam are some factors that contributed to the cirisis
She added that Iran is not going to stop drilling the lagoon, but devise ways to lessen side effects.
Ebtekar said that since 2 months ago, water is being let into the lagoon.
She rejected seeking clouds as changing things greatly in relation to the dust.
She also said that this year, the government spent 150 billion tomans in acquiring air pollution measuring devices.
A recent dust storm in Khuzestan sent many people to hospitals suffering respiratory problems and forced the government to close organizations.
