Over the past decade, a vast ancient Lake has been discovered in the central region of Iran, known as the Paleo Mega Lake of Rey. This paper aims to meticulously examine the provided data while accurately pinpointing to this lake. Additionally, significant data related to periods when the lake was filled with water has been acquired. Consequently, there is no longer any room for uncertainty regarding the presence of the lake during the era when humans resided in the territory of Iran.

The indicated place of the event, probably occurring in February–April 1880, is Booghin of in the historical Zarand district, 100 km NW from Veramin (Varamin).
