Its estuary has maximum depths that range from 7 to 22 m and hosts a saline wedge. The discharge of the river varies with the time of year with July being the month with the largest discharge (1293 m3/s) and March the one with the lowest (592 m3/s). During times of low discharge saline bottoms waters penetrate upstream all the way to its tributary Calle-Calle River.
The foraminiferal fauna of the wetlands adjoining the river is dominated by Trochamminita salsa.
