WHAT ARE AQUATIC INVASIVE SPECIES?

Aquatic invasive species (AIS) are non-native plants and animals that threaten native plants, wildlife, and their habitat. Fourteen AIS have already entered Canandaigua Lake, the most familiar is the Zebra mussel. There are many other AIS, such as Hydrilla, found in nearby waterways that could easily be transported to our lake on boats and trailers and have the potential to cause severe harm to Canandaigua Lake.

Once AIS are established, eradication is almost impossible. Many invasives may have a direct impact on boating and fishing areas, raising the concern of reducing water quality and reduced property values. Tourism may also be impacted when invasives are established.

CLWA works to prevent the introduction and spread of invasive species by partnering with the Watershed Council, the Finger Lakes Institue, NYS Parks, and the NYS DEC by offering a Watercraft Steward Program at the lake’s two busiest launch sites, the Canandaigua Lake State Marine Park and the DEC boat launch in Woodville. Stewards are on duty 7 days a week to assist with boat inspections to help ensure you are launching a clean watercraft!

HOW CAN YOU HELP?

Help protect Canandaigua Lake by following a few simple steps when boating.

CLEAN.

Remove all visible plants, animals, fish and mud from your boat trailer or other equipment and place in a disposal station, trash container or on dry land. Don’t forget to check your anchor!

DRAIN.

Drain all lake water holding compartments including bilge areas, live wells, and ballast tanks before leaving the launch.

DRY.

Dry all boats, trailers and equipment before use in another waterbody. Five days dry time is recommended.

Canandiagua Lake boaters are also offered at special deal with our partners at Auto Wash Car Wash. Boaters going to or leaving Canandaigua Lake are offered the first 16 minutes of a high pressure wash for FREE. Just find an attendant and let them know you want to do your part to use clean boating practices – it’s that easy!
