The local authority will soon install two floating barriers in Cul-de-Sac Bay to limit groundings SargassumSuspended due to the lack of a decree regulating, in particular, the ban on anchoring, their implementation can now be launched after publication of the text.
As part of the fight against massive sargassum strandings, the Collectivity plans to install two floating transfer barriers in Cul-de-Sac Bay. The first, long of 180 meters, will be installed to the north of the bay, while the second, of 520 metersThe installation will take place on the southwest shore. Boaters are asked to move their vessels to allow for the installation of the device. However, no specific start or end date for the work has been communicated. However, starting from September 11, 2026 , violations of the prohibitions set out in the territorial order may be subject to prosecution.
A A passage will be built between the two dams.in the deepest part of the bay, in order to preserve the passage of sailboats and vessels with limited draft. Access to the Cul-de-Sac pier and the connection to Pinel Island will remain maintained. Within the designated areas, the mooring and the mooring will be prohibited, as will swimming and water sports. underwater or fishing. The restrictions therefore do not apply to the entire bay.navigation remains possible through the constructed channel.
Collection at the heart of expectations
The principle of dams is to divert the floating sargassum and concentrate it in a small area, in order to facilitate their recovery before they wash ashore and decompose on the ground. This step, however, raises some questions. among local residents and the Anti-Sargassum Collective, particularly regarding collection and removal methods. During previous large-scale arrivals, collection capacities were sometimes severely strained. Therefore, further details will be needed concerning the collection point, the resources deployed, and the removal capacity in the event of a large influx. A study is also reportedly being launched to consider a pumping system., designed to improve recovery efficiency. The installation of the dams is therefore a first phase: their effectiveness will also depend on the capacity to collect and quickly remove the concentrated sargassum seaweed.. _Vx
