Although receiving freshwater from the Bahoruco Mountain Range, the lake is hypersaline due to sea water flowing into the lake through an underground system caused by a karstic depression. Salinity levels show seasonal changes due to precipitation, evaporation and the amount of freshwater input.
One of the most notable aspects of this lake is the greenish aspect of its water, caused by limestone sediments being dragged into the lake by the underground water flow.
Its unique flora and fauna are perhaps its most interesting feature; flamingos, Rhinoceros Iguana, mangroves, various species of endemic birds and several cays inside the lake are a common sighting.
