The task of dredging is entrusted to the Contractor Dragados Hidráulicos SA. For the execution of these tasks, 2 dredgers will be deployed—one in the stretch between 1km and 4km in Calamar, and another at 115km towards the mouth of the Cartagena Bay. Anticipated to span around 120 days, these endeavors are projected to remove an average of 3,000 m3 of material. The primary goal of these interventions is to effectively clear sediment material from the Magdalena River that has accumulated and hindered navigation within the canal and its mouth. This holistic approach not only serves the social welfare of the local communities but also maintains the fluid dynamics of the river system. Moreover, it ensures that navigability remains uncompromised under secure conditions while minimizing the environmental impact.

Covering an expansive 435,000 ha, the project extends over marine and continental domains. The Canal del Dique spans 115 km, linking Calamar municipality to Cartagena Bay in the Bolívar department. Key construction focuses include establishing 2 lock and gate complexes in Calamar and Puerto Badel. These structures will effectively manage water flow, combat saline intrusion, curb shoreline erosion, and minimize sedimentation in Cartagena and Barbacoas bays.
