Last year, 475 Asian clams — a small clam, less than 1.5 inches in size, that can spread rapidly — were removed from Lake George, thanks to a half day of work from about 20 volunteers as part of the Lake George Association’s Asian Clam Citizen Science Day in Sandy Bay.
Post-treatment survey results this spring suggested that the seven acres of mats placed on the bottom of Lake George last winter successfully killed off several populations of Asian clams. However, a two-week lakewide survey in early September has revealed that the invasive clams are showing up in new locations, and spreading beyond the treated areas.
New clam populations have been identified by volunteers and staff from the various organizations that make up the Lake George Asian Clam Task Force. New locations with clams have been found at Million Dollar Beach, Sandy Bay, Cotton Point and Basin Bay in southern Lake George, as well as the private boat launch area in Glenburnie in the Northern Basin. » Continue Reading.
The Lake George Asian Clam Rapid Response Task Force (Task Force) has conducted a lake wide survey to identify any additional sites of infestation since the discovery of Asian clam in Lake George waters in late summer of 2010.
The Warren County Board of Supervisors has voted almost unanimously to pass an invasive species transport law following a public hearing. The law, which took effect immediately, makes the introduction and transport of aquatic invasive species into Warren County waterbodies illegal.
It is the first county law of its kind to pass in New York State. The law imposes a fine of up to $5,000 and up to 15 days in jail for violators. Chestertown Supervisor and Executive Director of the Local Government Review Board Fred Monroe was the only supervisor to oppose the measure saying the penalties were too harsh. » Continue Reading.
A new infestation of the invasive species Asian clam (Corbicula fluminea) has been discovered in Lake George in Boon Bay in the Town of Bolton. The new infestation was discovered as part of the FUND for Lake George’s Eurasian watermilfoil management and control program in cooperation with the Lake George Park Commission. Initial survey work by the RPI Darrin Fresh Water Institute in Boon Bay estimates the population to be 3.75 acres – 5 acres in size.
This is the second infestation discovered in Lake George. Last fall a 5-acre infestation in the Village of Lake George was discovered. The Lake George Asian Clam Rapid Response Task Force organized to combat this infestation and a treatment effort has been underway in the Village since late April under permits from the Adirondack Park Agency and NYS Department of Environmental Conservation. Over 725 benthic barriers have been installed to suffocate the clams. » Continue Reading.
The 2011 Lake Steward Program on Lake George, managed by the Lake George Association, will significantly expand over last year’s level thanks to new funding provided by the Lake George Park Commission (LGPC).
Lake stewards, posted at several Lake George boat launches throughout the summer, inspect incoming boats for invasive species, remove suspicious specimens, and educate boaters about the threats of invasive species and how to prevent their spread. The Commission’s marine patrol is contacted whenever stewards encounter a boat being launched that has obvious signs of invasive species and is unwilling to be inspected. » Continue Reading.
The Darrin Fresh Water Institute’s (DFWI) annual program of testing waters near municipal beaches and town shorelines for coliform contamination will be less extensive this summer than in years past, according to Larry Eichler, a DFWI Research Scientist.
According to Eichler, The Fund for Lake George has withdrawn its financial support for the program.
While some municipalities may assume the costs of sampling waters near beaches, no organization has stepped forward to fund the monitoring of shorelines, Eichler said. “The FUND for Lake George has contributed more than $300,000 in cost sharing for this program over the past 25 years,” said Eichler. “But while still supporting the efforts of this program, The Fund is unable to fund this program due to other committments.”
Those other commitments, explained Peter Bauer, the executive director of The Fund for Lake George, include exterminating invasive species like the Asian clam and financing the West Brook Conservation Initiative, which will protect the lake’s south basin from urban runoff.
“Unfortunately, we are unable to continue funding the program,” said Bauer. “While it’s time for The Fund to transition out of the program, the importance of monitoring public beaches should motivate local governments to adopt at least that part of the program.”
Bolton, Lake George Village, the Town of Lake George and Hague have agreed to consider adopting monitoring programs, said Eichler.
“Evaluation of bathing beach water quality provides a reminder that water quality is not guaranteed and that proper maintenance and surveillance of swimming areas remain critical,” said Sandra Nierzwicki-Bauer, the executive director of the Darrin Fresh Water Institute.
According Larry Eichler, DFWI can test sampled waters for Total Coliform (TC), Fecal Coliform (FC), and Fecal Streptococcus (FS) for as little as $30 per week. The Towns would be responsible for the costs of collecting the water samples.
New York State’s Department of Environmental Conservation has tested the waters near state-owned beaches since the late 1980s, after the Million Dollar Beach was closed for three days in 1988 because of an excessive fecal coliform count.
The Darrin Fresh Water Institute has tested waters near municpal beaches every summer since 2002.
“The program was a low cost mechanism to provide assurances that the public beaches on Lake George posed no threats to the public,” said Larry Eichler.
“We continue to believe that this program provides a valuable service to the Lake George community through assurance of water quality at our public bathing beaches.”
Even before it began testing municipal beaches for coliform contamination, DWFI was sampling sites around Lake George for coliform bacteria, which are generally viewed as indicators of sewage leaks or other sources for nutrients, such as storm water.
“The Lake George Coliform Monitoring Program was designed to be a proactive water quality program,” said Eichler. “Prompt identification and remediation of wastewaters entering Lake George is one of the most efficient ways to protect water quality.”
Waters were evaluated at sites with chronically high levels of coliform bacteria or in areas where algae appeared, Eichler explained.
“We’re disappointed that The Fund could not continue to support the program, but we understand fiscal realities,” said Eichler.
Eichler said grants may permit the Darrin Fresh Water Institute to re-establish the colliform monitoring program in the future.
An aggressive plan has been released to attempt an eradication effort of the newest aquatic invasive species to Lake George – the Asian clam (Corbicula fluminea). An ad hoc coalition of environmental groups, scientists, and public agencies developed the Plan to Eradicate the Infestation of Invasive Species Asian Clam in Lake George, which details efforts starting after ice-out next month to try and rid the lake of the Asian clam. This plan, organized by the Lake George Asian Clam Rapid Response Task Force, details the scope of the problem in Lake George, long-term threats from this invasive, options for treatment, and details a plan that will try and eradicate this clam in the lake. » Continue Reading.
The Lake George Association has released a report with findings from the 2010 Lake Steward program. The Association considers the Lake George Lake Steward Program “a critical part of protecting the water quality of Lake George and preventing the spread of invasive species between waterbodies by boaters throughout the Lake Champlain Basin and the Northeast.” Despite the fact that dozens of aquatic invasive species have already made inroads nearby, only four are currently found in Lake George. » Continue Reading.
The Lake George Association (LGA) has been awarded a $25,000 grant from the Lake Champlain Basin Program for the 2011 Lake Steward program on Lake George. In previous years the LGA had received funds from New York State through the Lake George Watershed Coalition to run the aquatic invasives prevention program, but state budget cutbacks have made future funding unpredictable.
The Lake Steward Program provides invasive species education and spread prevention. Lake Stewards are trained and hired in early summer, then stationed at multiple boat launches around Lake George to educate boaters about the threats of aquatic invasive species, such as Eurasian watermilfoil, zebra mussels, curly-leaf pondweed, and most recently, the Asian clam. » Continue Reading.
Eurasian milfoil was discovered in Lake George in 1985; since then, approximately $3.6 million dollars have been spent to control the spread of the invasive aquatic plant.
Add to that the value of the time spent administering programs and writing grants, as well the cost of educating the public about the dangers of spreading invasives, and $3.6 million becomes a figure that easily exceeds $7 million.
“We’ve been conducting a milfoil management program since 1995, when the state’s Department of Environmental Conservation turned the program over to us,” said Mike White, the executive director of the Lake George Park Commission. “We’ve employed methods like hand harvesting, suction harvesting and laying benthic barriers over the plants, but we’ve only had enough resources to contain milfoil, and not enough eradicate it.” » Continue Reading.
Lake George and Lake Tahoe have more in common with one another than expensive second homes and classic wooden boats.
“Both are known for gorgeous scenery, excellent water quality and high biodiversity. Both are very important economically as well as ecologically,” said Sandra Nierzwicki-Bauer, the director of RPI’s Darrin Fresh Water Institute. » Continue Reading.
The colony of Asian clams discovered in Lake George last week appears to be confined to an area between English Brook and Pine Point in the Village of Lake George.
“As far as we can tell, the population is contained within a relatively small area,” said Peter Bauer, executive director of The Fund for Lake George. “More research will follow this week and next to verify this. We’ll also survey other areas that appear to be suitable habitat for the species. But if we’re lucky and maybe this is an isolated infestation that we caught early, then eradication of this invasive species is a strong possibility.” » Continue Reading.
Asian carp are all over the news and will soon be all over Lake Michigan unless the Chicago canal that links the Mississippi and Great Lakes watersheds is re-engineered. It’s looking unlikely, but if the Obama administration decides to turn this dilemma into a major public works project—keeping a particularly nasty invasive species from upending the remnants of native Great Lakes fish life—there’s a canal on Lake Champlain that could use a lift too. » Continue Reading.
