MAINTENANCE OF THE MARINA SITE:
To stop the spread of algae, which can really interfere with navigability in Castets-en-Dorthe marina and with the development of river transport activities, Lyonnaise des Eaux regularly cuts back invasive waterweeds.
WATERWEED CUTTING OPERATIONS:
When waterweeds develop in a marina, it is vital to cut them back or remove them regularly. The exotic water plants found at Castets-en-Dorthe marina spread quickly in stagnant water and invade sectors where water levels are less than 2.5m deep.
