Fed by numerous local springs, some of which are called vitouards (small streams with intermittent resurgences). It was said that the vitouard of Anisy sometimes aroused curiosity because it sometimes remained without flowing for several years and then suddenly grew and flooded the valley, penetrating houses, stables and barns to the point where it could drown livestock. The inhabitants had to flee, then the flooding stopped and the stream returned to its bed for several years. In the 20th century, the commune built an aqueduct under the road to remedy the problem of the water overflow.
Once a dependency of Anisy castle, this pond was used to water the farmers' livestock, as there were no drinking troughs or washhouses in the commune. Today, we can find the "Alytes obstetricans" toad, which is the scientific name of the pond. This significant 5-centimetre long batrachian can be distinguished by the fact that the male, after mating with the female, takes care of the egg-laying, which he twists around his legs until the tadpoles are born.
Great crested newts, as in the Anguerny pond, have also found refuge here.
