The lake is entirely filled by rainfall, which is usually about 8,000 millimetres (310 in) per year. The water is acidic with a pH ranging between 4.5 and 5. Its temperature ranges between 18 and 19 °C.
Flammarion is free of vegetation, but rather rare species that prefer the acidic conditions grow on its shores, such as Blechnum l'herminieri, Isachne rigidifolia and Juncus guadeloupensis, an endemic species of rush.[3]
The crater was named by the famous alpinist Mr. Camille Thionville, chef du service de l'Enregistrement et des Domaines.[2]
