Help Collar the Water Flea

The spiny water flea, an invasive zooplankton species first introduced into Lake Ontario, has found its way into the Adirondack Park. This species can outcompete native zooplankton which are an important food source of trout, salmon and other valuable fish species. Water fleas can also impair fishing by clogging rod guides and fishing reels. The water flea and other microscopic aquatic invasive species are commonly spread by boaters who do not adequately drain a boat’s bilge area, live well, bait well, or ballast tanks prior to use in another waterbody. They can also be spread on fishing lines, downrigger cables, anchor lines and other equipment previously used in waters containing spiny water flea.

Spiny or fishhook water-fleas have been confirmed in the following waters: Lake Champlain, Lake George, Indian Lake, Great Sacandaga Lake, Sacandaga Lake, Peck Lake, Lake Pleasant, Piseco Lake, Stewart Bridge Reservoir, Lake Ontario, St. Lawrence River, Seneca Lake.

You can help stop the spread of this invasive species by:

  • Completely drying fishing equipment and all water-holding areas of your boat. OR
  • Decontaminating fishing equipment and all water-holding areas with hot water (at least 140° F). You can do it yourself or visit a boat wash station. Locations can be found at ADKcleanboats.com.

If drying or decontaminating are not possible, thoroughly flush your boat and equipment with water free of water fleas in an area that will not drain into the water body you will be fishing or boating on.
