Guidance for clubs and managers of water bodies

Invasive plants and animals harm the environment, block waterways, clog equipment, and can be costly to manage. They can be small and hard to spot so are easily spread on damp equipment and clothing. Once established they become extremely difficult and expensive to eradicate, which is why it is so important to prevent their spread in the first place.

Below are some suggested actions that can help protect the water bodies you manage or use.

Educate your members and visitors:

Help them to follow Check Clean Dry:
        • Limit access to water bodies, preferably to a single point where Check Clean Dry signs are displayed. Visitors should log in and out, confirming that they have cleaned and inspected their equipment.
        • Install cleaning facilities at access points if you can.
        • If possible, provide equipment that can be borrowed and used in club waters instead of personal equipment (e.g. trailers for boaters, nets and drogues for anglers).
        • Put Check Clean Dry stickers on any club-owned equipment to remind users to follow the guidance.
        • Consider additional measures for competitions and events.
