Gunky, icky spiny water flea spreads in Adirondacks

Scientists and activists studying invasive species say the spiny water flea is spreading to more lakes in the Adirondack Park.

The organism had already been found in Great Sacandaga and Lake George. This summer, the invasive creature was found in Lake Pleasant and Piseco Lake.  Go to full article

NY takes aim at invasive species

ALBANY, N.Y. (AP) Officials in New York are enlisting the public's help in going after invasive species.

Gov. Andrew Cuomo said Monday that citizens can help combat invasive plants and animals by learning how to recognize them and prevent their spread.  Go to full article

Ontario will roll out invasive species plan today

ONTARIO Natural Resources Minister David Orazietti is set to make an announcement today about fighting invasive species in the province.

Last year, environmental commissioner Gord Miller noted that there's no funding
or plan to deal with invasive species like the emerald ash borer and Asian carp.  Go to full article

Botulism kills hundreds of loons in Lake Ontario

Type E Botulism, a disease caused by a toxic bacteria, is back in Lake Ontario. And over the last month or so, it's killed several hundred loons, ducks and other birds.

Type E Botulism has triggered annual bird kills in several Great Lakes since the late 1990s. But they've been largely minor on Lake Ontario for the last seven years. That is until residents around Henderson Harbor and Ellisburg in Jefferson County started calling the DEC in late October.  Go to full article

Netting a snapshot of the St. Lawrence River fishery

Every year since 1976, state environmental technicians have set nets across the St. Lawrence River to see what fish they catch. The result is a sort of snapshot of the river's fishery.

David Sommerstein bumped into the Department of Environmental Conservation crew last month at Coles Creek marina. They were prying big and little fish from nets and tossing them into buckets for testing. Roger Klint is an aquatic biologist with the Department of Environmental Conservation and leads the DEC's annual index of fish populations in the St. Lawrence River.  Go to full article

A mystery at the bottom of the Great Lakes food web

Phytoplankton - the algae that are food for plankton which in turn feed fish - are behaving strangely. They're surrounded by a nutrient they need to grow. But for some reason, they're not using it.

The puzzle has big implications for how scientists think about the Great Lakes' future in a warming world. David Sommerstein reports from the St. Lawrence River.  Go to full article

New Seaway chief seeks economic, green balance

Shipping on the St. Lawrence Seaway generates billions of dollars for the Great Lakes economy in the U.S. and Canada. But it also opened the door to damage from invasive species and forever changed the shape and ecology of the St. Lawrence River itself.

The new U.S. chief of the St. Lawrence Seaway is making her first visit to Massena this week. Betty Sutton is touring the Seaway's two locks on the St. Lawrence River, the vessel traffic control room, and meeting with many of the Seaway's 135 employees in Massena.

Betty Sutton's very first appointment in Massena was a sit-down with David Sommerstein.

CORRECTION: A previous version of this story (and the audio version) refer to the Seaway Administration position as a seven year term.

That is no longer the case, as Nancy Alcalde, SLSDC spokeswoman, points out. In 2002, The Appointment and Efficiency Streamlining Act of 2011, P.L. 112-166, made this position an appointment "at the pleasure of the President". It is also no longer subject to U.S. Senate confirmation.  Go to full article

Park regulators approve herbcide for Loon Lake milfoil battle

The state Adirondack Park Agency voted unanimously Friday to approve the controversial use of a chemical herbicide to kill invasive plants in a lake in Warren County.

The Town of Chester plans to disperse 1,500 gallons of Renovate OTF in the southeastern corner of Loon Lake this spring.

It's an herbicide used to kill Eurasian watermilfoil, which has clogged waterways across the Park and has been a nuisance to boaters and swimmers.

This would be only the second time Renovate has been used in the Adirondack Park.  Go to full article

NY commmits new money to stop Lake George invasives

State Environment Commissioner Joe Martens was in in the North Country on Friday, unveiling $250,000 in new funds to help stop invasive species from reaching Lake George.

The money will go to help a local coalition pay for boat washing and inspection stations around the lake.

"We were able to tease out $250,000 extra for Lake George," Martens said.

"Depending on what the outcome is of this last fall's and next spring's program on the lake, we'll go back and see if we can't dedicate more funds to it."  Go to full article

Seaway digs out from recession

The St. Lawrence Seaway, and its commerce between Great Lakes ports and countries around the world, got hammered by the recession.

Craig Middlebrooks, acting administrator for the U.S. side of the binational waterway, says the steep drop was between 2008 and 2009. "It was almost a 25 percent drop. And I think '09 tonnage was among the lowest for decades."

Middlebrooks says the Seaway's been creeping back to pre-recession levels since then. Last year helped. Tonnage rose almost four percent, driven by coal and iron ore exports to China and Europe and U.S. steel imports. Industrial wind components also continue to be strong.  Go to full article
