SALISBURY — The Twin Lakes Association is taking an earlier and more aggressive approach to fighting the spread of invasive hydrilla in East Twin Lake by dosing the whole northeast bay, from May through October, with low-level herbicide treatments instead of spot treatments.
The goal, said Russ Conklin, the TLA’s vice president of lake management, is to sustain herbicide concentration over the 2025 growing season.
That plan of attack will continue over a period of 60 to 90 days beginning May 21, Conklin explained during the association’s April 30 membership meeting via Zoom which drew 60 attendees.
TLA officials were encouraged by the chance to stop the spread and hopefully destroy the thick mats of the unyielding invasive plant hydrilla verticillata, referred to as the Connecticut River variant, after two years of chasing new growth around the lake’s north bay.
Dense patches were first discovered in the summer of 2023 in shallow waters around O’Hara’s Landing Marina and the nearby state boat launch and the plant has since migrated further into East Twin, following a pattern of boat traffic.
Past treatment efforts were hampered by delayed permits from the state Department of Energy and Environmental Protection to treat the hydrilla with herbicides in an area where a rare plant had been identified.
This year, the TLA was granted an exception by DEEP, said Conklin, as any protected plant species in the path of hydrilla would likely not survive anyway.
“It is not dead now, but it is going to be if we don’t do something about the hydrilla.”
“This is a big year for us,” Conklin said. “Hydrilla is a real threat to the lake, and we did treat it this past year, but the permits only applied to the plant, so we spot treated it … and were always chasing it.”
The course of action this year, he said, is to treat the entire northeast bay with the herbicide Sonar in both liquid and crystal form at a very low levels so that the herbicide’s contact time with hydrilla will be extended for a longer period over 60 to 90 days.
“We know from past experience that it is much easier to kill the plant when it’s small,” Conklin explained. The goal, he said, is to attack the stringy, green weed before August when it crowns and splits into numerous growing points that are capable of growing at the rate of an inch a day.
During the hour-long meeting, discussion also focused on a pilot program for enhanced cyanobacteria monitoring at Twin Lakes to be headed by TLA director Jessica Swartz, a resident of West Twin Lake and biotech executive with Pfizer.
“It’s very visibly challenging to identify cyanobacteria blooms,” Swartz explained, as it can easily be confused with pollen on the surface of the water, dead vegetation or different types of algae.
Cyanobacteria, also known as blue-green algae, are natural, important phytoplankton in lake ecosystems. Dense blooms, which release toxins, occur when there is an abundance of sunlight, elevated phosphorus levels and warm temperatures.
Given the current escalation in overly-nutrient rich waterbodies and rising temperatures due to global climate change, the frequency of cyanobacteria blooms is increasing, said Swartz, and Twin Lakes has occasionally experienced localized blooms.
As a result, the association will be implementing a pilot testing program with greater frequency and at more locations than currently conducted by the TLA’s limnologist, George Knoecklein. The goal of the pilot program is to work out the process of collecting reliable data over time that helps inform whether cyanobacteria blooms are occurring, where they are most frequently found, and assess the level of risk.
Sample test kits have been ordered for five or six testing sites across East and West Twin, including at the private Salisbury School.
TLA president Gant Bogle invited Swartz to give an update at the association’s upcoming June 14 membership meeting at Camp Isola Bella.
Despite rising lake management costs projected at $500,000 this year, Bogle reported that the TLA is in strong shape financially heading into the 2025 season, as it received another $75,000 grant from DEEP and $25,000 from the Bates Foundation to support the Watershed Study.
Also, the town of Salisbury has earmarked $75,000 for Twin Lakes this season, said Bogle, and the TLA membership has “responded generously” contributing more than $300,000 since August 2024 when the group started its 2025 fundraising campaign.
Bogle also encouraged members to attend the May 12 public meeting of the Salisbury Inland Wetlands & Watercourses Commission, which is expected to address proposed changes to the Upland Review Area encompassing the town’s lakes.
The LED sign in front of Amenia's Town Hall on Route 22 warns passing motorists of the current temporary burn ban, in effect from Oct. 2 to Oct. 15.
A statewide burn ban is in effect as of Thursday, Oct. 2, the New York State Governor's office announced in a press release.
The temporary ban is in effect until at least Oct. 15, and the statement released by the governor's office said the restrictions will be re-evaluated prior to the Oct. 15 deadline.
Lighting fires for brush or debris disposal and large, uncontained fires for cooking or other purposes are banned until at least Oct. 15 under the statewide order. Backyard fire pits, contained camp fires no larger than 3 feet in height and 4 feet in diameter, and small, contained cooking fires are still permitted under the burn ban.
New York State has faced dry conditions all autumn, triggering drought watches and warnings across most of the state.
Dutchess County, along with the other counties in the Catskills region, are under a drought watch according to the Department of Environmental Conservation's drought condition map.
Dutchess County is currently under a "high" fire danger rating, according to the DEC.

Volunteers were hard at work putting the finishing touches on the crucial creepy decorations for the Haunted Fortress of Stanford on Sunday, Sept. 28.
STANFORD — Greg Arent led a devoted team of volunteers on Sunday, Sept. 28, in a final push to prepare Stanford’s Haunted Fortress for opening day.
Final touches included cleaning the bottomless pit, scrubbing the pirate ship, raking the graveyard and dressing the dolls. By 2 p.m., about 20 volunteers had assembled to creepify the beloved local landmark.
Many of the volunteers have been coming back for years, Arent said, dedicating time and valuable skills to the town-owned haunted house that was constructed by the artist Peter Wing.
Arent has been building sets in his free time for forty years, but he started out volunteering with the Haunted Fortress in 2014 when his children wanted to get involved, he said. At that time he would help out one or two days a year. That grew into a leadership position over the course of a decade.
On Sunday, Arent was touring the decrepit grounds checking light bulbs, soundtracks and other set details to contribute to that perfect spooky ambience.

When it’s all said and done, the Fortress will be ready to welcome visitors starting on Friday, Oct. 3, with shows running from 6:30 to 9:30 p.m. on Fridays and Saturdays and 6:30 to 8:30 p.m. on Sundays. The Haunted Fortress is entirely staffed by volunteers, Arent said, including the actors that don costumes to scare visitors. Anybody aged 6 and up can volunteer to act in the horror show, and families often will volunteer to take over a scene.
“I love it because every scene is different every night,” Arent said. “Sure there are going to be vampires in this scene, but this family is going to do it different from these three kids from Bard, who are going to do it different from these three middle school kids.”
The sets themselves were all built from recycled material to be as creepy and decrepit as possible, Arent said. Concrete culverts adorn the sides of a bridge over a stream, stacked vertically with a cone on top to elicit a fortress’s spires. Reclaimed lumber bolted to a fence evokes a dark and scary forest blocking any escape. A rusting tractor with a steel box welded above the seat sits on a set of rails with two cars attached to it, mimicking a wrecked train with it’s inner mechanisms exposed and blowing steam on passersby.
This year the Haunted Fortress is following a haunted circus theme featuring clowns and other carnival staples alongside the classic settings of the Fortress.
The team of volunteers is dedicated and numerous, and the Stanford Highway Department lends a hand too, Arent said, but there’s always a need for skilled labor at the local attraction.
And the group appreciates all the help they can get. “Whatever you’re interested in and capable of doing,” Arent said.

MILLERTON — The Village announced a leadership change at the Highway Department on Friday following the resignation of Superintendent Peter Dellaghelfa. Police Chief Joseph Olenik will step into the role, effective immediately, officials said.
Olenik will continue to serve as Police Chief.
The decision was made Friday, Sept. 26, during an emergency meeting of the Board of Trustees following Dellaghelfa’s resignation.
Mayor Jenn Najdek said the “amicable split” with Dellaghelfa was part of an ongoing annual employee review process, adding that turnover is not uncommon in small municipalities. She expressed her gratitude for Dellaghelfa’s service over the last four years.
The Board went into Executive Session on Aug. 26 and Sept. 9 for “matters leading to the appointment, employment, promotion, demotion, discipline, suspension, dismissal or removal of a particular person,” but village officials could not comment on the specifics of those discussions.
The leadership shift will allow the Village to “better respond to the changing needs of our residents and community,” announced the Board in a press release shared with The News. “The Mayor and Board are excited to see Joe expand his impact on Millerton and we’re confident this change will bring lasting improvements to operations, communications and community engagement.”
Police Chief Olenik, who will continue his leadership role within the Millerton Police Department, said he is looking forward to the added responsibilities.
“I am excited to help move the department forward and rebuild it after the devastating fire,” Olenik said. “I am also looking forward to working with the dedicated staff and helping the residents of Millerton by making needed changes and repairs.”
Though Olenik will assume additional responsibilities as he leads the Highway Department, the Millerton Police Department will continue to operate separately — but with the same shared goals of supporting the village community.

Mayor Najdek added that Olenik has extensive supervisory and administrative experience that, given the imminent need to rebuild the Highway Department building, will be critical. In addition to managing the upcoming construction, his first orders of business will include making sure the village is on track for leaf pick-up and snow removal, working to ensure the right equipment and personnel are in place.
Olenik held his first meeting with the Village Highway Department on Monday, Sept. 29 and discussed a new leaf container — built by Millerton’s Highway Department — that will support efforts to collect leaves. The leaves will then be turned over to McEnroe’s Organic Farm for composting. While the team configuration — which includes Jim Milton, William J. Clark, and Spencer Parks — will be new, Olenik said they are not strangers. “They’ve always helped me out and I’m looking forward to working with them more closely.”
The Board said in a statement the Village is in good hands moving forward. “Joe’s leadership style — hands-on, structured, and community-focused — makes him well suited to guide this department through the transition.”
