Emerald Ash Borer Now in Duchess County - Remember - Don't MOVE firewood

EABswirlpatternThe DEC has announced the discovery of the Emerald Ash Borer (EAB) in Dutchess County directly across the Hudson River from the large infestation found two years ago in the city of Kingston. This marks the first discovery of EAB east of the Hudson River.

"This means the EAB is closer than ever to Lake George," said LGA Education Director Emily DeBolt. "We need everyone to be on the look out for signs of this highly destructive beetle," she said. 

It's also very important, as you prepare to head to Lake George for the summer, that you remember NOT to move firewood. The EAB and other invasive species spread through firewood.

Untreated firewood is banned from entering the state and intrastate movement of untreated firewood is restricted to no more than a 50-mile radius from its source.

EABholedec.nyThe EAB is a small but destructive beetle that infests and kills North American ash tree species, including green, white, black, and blue ash. (See the signs of the beetle - S-shaped galleries and D-shaped exit holes pictured here. Galleries under the bark reveal the back and forth feeding pattern of the EAB larvae. Adults emerge from D-shaped exit holes, typically 1/8″ in diameter.  See more signs here.)

Since it was first discovered in Michigan in 2002, EAB has been responsible for the destruction of 70 million trees in the United States. New York has more than 900 million ash trees, representing about seven percent of all trees in the state, and all are at risk from EAB.

“Emerald ash borer has been reported in new counties each year since it was first discovered in New York. Private citizens are usually the first to see signs of forest pest damage, and these detections can serve as an early warning system for its spread. Please keep your eyes open for emerald ash borer in the Adirondacks and report any suspicious sightings. Citizen action does make a difference,” said Hilary Smith, director of the Adirondack Park Invasive Plant Program.

Lake George CSLAP Reports for 2011 Online
CSLAPJulieVanDornLake George water quality data for 2011 has been released by the Citizen Statewide Lake Assessment Program (CSLAP). Since 2004, the Lake George Association has participated in CSLAP, which is coordinated by the New York State Dept. of Environmental Conservation (NYS DEC) and the New York State Federation of Lake Associations. 
 
In 2011, LGA volunteers monitored mid-lake sites near Diamond Island, Harris Bay, Basin Bay, Huletts Landing, Crown Island, Gull Bay, and Hearts Bay. (See Julie Nathanson, LGA CSLAP volunteer at left.) Each year, trained volunteers collect and process water samples throughout the summer. Please see the LGA website for the full reports.

The lake continues to be characterized as oligotrophic at all sites, based on water clarity, total phosphorus readings and chlorophyll a readings.
 
An oligotrophic lake has the lowest nutrient content, and consequently, low algal production, and often very clear waters, with high drinking-water quality. The bottom waters of oligotrophic lakes typically have ample oxygen, so they can support many fish species, like lake trout, which require cold, well-oxygenated waters.
 

Water Clarity
Water clarity readings were lower than normal at the Diamond Island site, (consistent with its higher phosphorus readings), and at the Harris Bay site. The Harris Bay site has seen a long-term trend toward decreasing clarity. Water transparency was also lower than normal in the northernmost and southernmost sites in August, but higher than normal in the mid-lake sites at the same time.
 
In contrast, Basin Bay has seen an increase in the water clarity since 2004. Nearly all of the water clarity readings at this site have been high.
 
Potability
Algae levels are not high enough to render the lake susceptible to taste and odor compounds or elevated DBP (disinfection by product) compounds that could affect the potability of the water. Hypolimnetic phosphorus, ammonia, iron, manganese and arsenic readings are low or close to those measured at the lake surface at all sites.
 
Chemical Presence
At all sites, the Lake can continue to be characterized as a slightly alkaline, softwater, uncolored Lake, with low nitrogen levels.  There are only slight differences from site to site.

 
 
Please Keep VOTING for the LGA's Floating Classroom. 
Teens-Afloat_canvas_760Just one more day of voting...

Please help the LGA receive discounted life jackets for the teens who come on board our Floating Classroom. VOTE for the LGA today and tomorrow. (We are behind in the voting, so we REALLY need YOUR help!)  

This new program from the BoatUS Foundation will provide local, US-based nonprofit organizations an opportunity to apply to purchase teen-sized life jackets at a discounted rate of $5 per jacket (jackets retail for about $25) to be used in their on-the-water programs.

 

Floating Classroom Back on Water May 16
Join us for Wednesday and Friday public programs this summer.
FloatingClassroomonwater3Floating Classroom programs begin May 16. Schools participating this spring are: Queensbury, Argyle, Corinth, South Glens Falls, Glens Falls, Granville, Hartford, and Hadley Luzerne.

Would you like to go out too? You can! Please join us on a 2-hour public trip on a Wednesday in July or August, at 10 am or 1 pm. We’ve also added THREE NEW FRIDAY programs!  

And we are booking group trips for the summer!  Why not invite your hotel guests or homeowners association to go out on a trip designed for them?


Check the LGA website event page for more details, use the online reservation request form, or give us a call.
 
Asian Clam Update - Boon Bay to be Main Focus
LGACRRTF logoThis summer’s main focus will be on Boon Bay.  LGA staff was out on the bay in April, assisting with survey efforts to determine the full extent of the infestation there and how best to proceed.

A new and comprehensive report on the Asian Clam eradication project (2011 activities and plans for 2012) is now available on the stoptheasianclam.info website.

The treatment for Boon Bay will be the largest in 2012 of the four infested areas in the Lake.

BOON BAY: Current plan from the Lake George Asian Clam Rapid Response Task Force

AsianClamSurveyinBoonBay1. Divers have completed the survey of the southern and northern ends of the infested area to ascertain the limits of the infestation.  (See LGA staff helping with survey in picture at left.)

2.
Based on survey results, a crew has started to install benthic barrier mats. Mats are being installed side by side from one end of the infested area to the other, in a piano-key formation. We are working with homeowners and resort owners to make them aware of the treatment areas. This may cause a slight inconvenience to boat traffic in the area while mats are in place and we ask that all boaters use caution when in this area. Please note: A temporary no-wake zone may be established for the duration of the project. To minimize the disruptions, mats were put into the Lake as soon as feasible, to begin the 45-day clock as early as possible. Up to 500-600 mats may be needed.

3. Special mats with ports for measuring dissolved oxygen (DO) will be installed at regular intervals. The Darrin Fresh Water Institute will monitor these ports during the treatment. Maintenance of the mats will occur weekly.

4. If feasible, all mats will be removed by late June.

5. In September, Boon Bay will be re-surveyed and all locations with live clams will be marked for treatment. The task force is planning only “spot” treatments in the fall and not another large treatment.

6. Installation of mats will begin in September. Installation of some mats in near-shore areas where they may disrupt tourism facilities could be delayed until after Columbus Day weekend.

7. Mats will be removed in early December.
