New York State Will Work with Partners to Implement Lake Champlain Task Force Recommendations
The presence of the spiny water flea, an aquatic invasive species,
was confirmed in Lake George, the New York State Department of
Environmental Conservation announced today.
"DEC has worked with its partners on the Lake Champlain Basin Task
Force to stop and slow the spread of the spiny water flea," DEC
Commissioner Joe Martens said. "The discovery of spiny water flea in
Lake George is not welcome news and DEC's efforts to slow the spread of
this and other invasive species will continue."
Earlier this week the Lake Champlain Basin Aquatic Invasive Species
Rapid Response Task Force released seven recommendations to slow the
spread of spiny water flea into Lake Champlain, which includes
redirecting the flow of the Champlain Canal into the Hudson River and
furthering a feasibility study for a hydraulic barrier between the
Champlain Canal and Lake Champlain.
"DEC fully supports the recommendations of the Task Force and will
work with the state of Vermont and our other partners to implement the
Task Force's recommendations," Commissioner Martens said. "Boaters and
anglers also have a major role in slowing the spread of invasive
species. All boating, fishing and recreation equipment must be cleaned
and disinfected, to prevent spreading invasive species to other water
bodies."
The Task Force is made up of representatives from New York state,
Vermont and Canada. The Task Force's report recognizes that the closure
of the Champlain Canal and the Glens Falls Feeder Canal is not
technically, legally or economically feasible.
The discovery of spiny water flea in Lake George provides another
pathway for the invasive species to enter Lake Champlain via the LaChute
River. Lake George is not connected to the State Canal System.
The presence of spiny water flea was confirmed through sampling
efforts by the Lake George Association on Tuesday, July 31. The samples
were taken to the Darrin Fresh Water Institute where four spiny water
fleas were identified.
"Right now the Commission's top priority is invasive species control
and management, and we will work with our many partners on determining
the extent of this population," Dave Wick, Executive Director of the
Lake George Park Commission, said. "The Commission is currently
developing a comprehensive invasive species prevention plan for Lake
George, with the goal of preventing any new invasive occurrences from
entering the lake."
The possible presence of the spiny water flea was first reported on
Friday, July 27 by an invasive species steward at DEC's Mossy Point Boat
Launch near the north end of the lake. A fisherman had reported having a
clump of small organisms on his fishing line after spending time
trolling the waters off Mallory Island along the east shore of the lake.
The steward took a sample and provided it to the Lake George
Association, who passed it on to the Darrin Fresh Water Institute. After
the organisms were identified as spiny water fleas the Lake George
Association sampled the waters off Mallory Island and further confirmed
its presence.
The invasive pest was previously confirmed in the Great Sacandaga
Lake in 2008, Peck Lake in 2009, Stewarts Bridge Reservoir 2010,
Sacandaga Lake in 2010 and most recently this summer in the Champlain
Canal and Glens Falls Feeder Canal.
Background on Spiny Water Flea
Native to Eurasia, the spiny water flea feeds on tiny crustaceans and
other zooplankton that are foods for fish and other native aquatic
organisms, putting them in direct competition for this important food
source. The tail spines of the spiny water flea hook on fishing lines
and foul fishing gear.
Spiny water fleas can impact aquatic life in lakes and ponds due to
their rapid reproduction rates. In warmer water temperatures these water
fleas can hatch, grow to maturity, and lay eggs in as little as two
weeks. Conversely, "resting" eggs of spiny water fleas can remain
dormant for long periods of time prior to hatching.
While it is not clear when or how the spiny water flea was introduced
into the lakes, it is clear that the initial introduction, and very
likely the others as well, were through adult, larvae or eggs being
transported to the waters by bait bucket, bilge water, live well, boat,
canoe, kayak, trailer or fishing equipment.
Currently, there are no successful means to control or eradicate this
and many other aquatic invasive species, so preventing their spread is
the only means for reducing their impacts on native aquatic communities.
It is very important that boats, anglers and other recreational
enthusiasts take precautions to avoid transporting this and other
invasive species, particularly after leaving water known to have an
aquatic invasive species.
Prevent the Spread of Spiny Water Flea
INSPECT & CLEAN your fishing, boating and other
water recreation equipment and gear. Remove all mud, plants and other
organisms that might be clinging to them when leaving waters, especially
those that are known to contain an aquatic invasive species.
DRY your fishing and boating equipment before using
it on another body of water. Drying is the most effective "disinfection"
mechanism and is least likely to damage sensitive equipment and
clothing. All fishing and boating equipment, clothing and other gear
should be dried completely before moving to another body of water. This
may take a week or more depending upon the type of equipment, where it
is stored and weather conditions. A basic rule of thumb is to allow at
least 48 hours for drying most non-porous fishing and boating gear at
relative humidity levels of 70 percent or less.
DISINFECT your fishing and boating equipment if it
cannot be dried before its use in another body of water. Disinfection
recommendations vary depending on the type of equipment and disease of
concern. Be particularly aware of bilge areas, live wells and bait wells
in boats. These areas are difficult to dry and can harbor invasive
species.
See the DEC website for more information on
invasive species and how you can stop their spread.
