The maximum depth of the lagoon is 30 m. The northern part of the lagoon is deep with a major longitudinal basin (major axis NW-SE) (water depth 25-30 m) and smaller longitudinal basin at the southwest of the northern part with water depth 15-20 m. These two basins are separated by a longitudinal shallow ridge trending WNW-ESE (water depth 10 m) which is the offshore continuation and/or related to gypsum deposits and evaporites at the western margin of the lagoon.
