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 Grant 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.
SHARON — Sharon Dennis Rosen, 83, died on Aug. 8, 2025, in New York City.
Born and raised in Sharon, Connecticut, she grew up on her parents’ farm and attended Sharon Center School and Housatonic Valley Regional High School. She went on to study at Skidmore College before moving to New York City, where she married Dr. Harvey Rosen and together they raised two children.
Sharon’s lifelong love of learning and the arts shaped both her work and her passions. For decades, she served as a tour guide at the American Museum of Natural History and the Asia Society, sharing her knowledge and enthusiasm with countless visitors. She also delighted in traveling widely, immersing herself in other cultures, and especially treasured time spent visiting her daughter and grandsons in Europe and Africa.
She was also deeply connected to her hometown, where in retirement she spent half her time and had many friends. She served as President of the Sharon East Side Cemetery until the time of her death, where generations of her family are buried and where she will also be laid to rest.
She is survived by her husband, Harvey; her children, Jennifer and Marc; and four beloved grandchildren.
Claire and Garland Jeffreys in the film “The King of In Between.”
There is a scene in “The King of In Between,” a documentary about musician Garland Jeffreys, that shows his name as the answer to a question on the TV show “Jeopardy!”
“This moment was the film in a nutshell,” said Claire Jeffreys, the film’s producer and director, and Garland’s wife of 40 years. “Nobody knows the answer,” she continued. “So, you’re cool enough to be a Jeopardy question, but you’re still obscure enough that not one of the contestants even had a glimmer of the answer.”
Garland Jeffreys never quite became a household name, but he carved out a singular place in American music by refusing to fit neatly into any category. A biracial New Yorker blending rock, reggae, soul and R&B, he used genre fusion as a kind of rebellion — against industry pigeonholes, racial boundaries and the musical status quo. Albums like “Ghost Writer” (1977) captured the tension of a post–civil rights America, while songs like “Wild in the Streets” made him an underground prophet of urban unrest. He moved alongside artists like Lou Reed and Bruce Springsteen but always in his own lane — part poet, part agitator, part bridge between cultures.
“I think what I tried to do with the film, wittingly or unwittingly, was just to show that we all have these lives and they don’t often meet our dreams of what we think we’re entitled to, we’re talented enough to get or whatever,” said Claire. “We all have these goals, but we’re sort of stymied. Often, it’s partly circumstance and luck, but it’s also very often something that we’re doing or not doing that’s impeding us.”
This is not the typical rock-and-roll redemption story. There are no smashed guitars, no heroic overdoses, no dramatic comeback tour. What we get instead is something quieter and more intimate: hours of archival footage that Claire spent years sorting through. The sheer effort behind the film is palpable — so much so that, as she admitted with a laugh, it cured her of any future ambitions in filmmaking.
“What I learned with this project was A, I’m never doing it again. It was just so hard. And B, you know, you can do anything if you collaborate with people that know what they’re doing.”
Claire worked with the editing team of Evan M. Johnson and Ben Sozanski and a slew of talented producers, and ended up with a truthful portrayal — a beautiful living document for Garland’s legions of fans and, perhaps most importantly, for the couple’s daughter, Savannah.
“She’s been in the audience with me maybe three or four times,” said Claire. “The last time, I could tell that she was beginning to feel very proud of the effort that went into it and also of being a part of it.”
Savannah pursued a career in music for a while herself but has changed tracks and become a video producer.
“I think she couldn’t quite see music happening for herself,” said Claire. “She was like, ‘I don’t know if I want to struggle the way I saw my dad struggling and I’m going to get a job with a salary.’”
The film doesn’t just track the arc of an underappreciated musician, however. The music, always playing, is the soundtrack of a life — of a man navigating racial, musical and personal boundaries while balancing marriage, parenthood, aging, addiction andrecovery. Garland and Claire speak plainly about getting sober in the film, a life choice that gave them both clarity and shows Claire as a co-conspirator in his survival.
“I did some work early on with a director,” said Claire. “He wanted the final cut, and I didn’t feel like I could do that — not because I wanted so much to control the story, but I didn’t want the story to be about Alzheimer’s.”
Diagnosed in 2017, Garland, now 81, is in the late stages of the disease. Claire serves as his primary caregiver. The film quietly acknowledges his diagnosis, but it doesn’t dwell — a restraint that feels intentional. Garland spent a career refusing to be reduced: not to one sound, one race or one scene. And so the documentary grants him that same dignity in aging. His memory may be slipping, but the film resists easy sentimentality. Instead, it shows what remains — his humor, his voice, his marriage, the echo of a life lived on the edges of fame and at the center of his own convictions.
The Moviehouse in Millerton will be screening “The King of In Between” on Sept. 20 at 7 p.m. Peter Aaron, arts editor of Chronogram Magazine will conduct a talkback and Q&A with Claire Jeffreys after the film. Purchase tickets at themoviehouse.net.
The Haystack Book Festival, a program of the Norfolk Hub, brings renowned writers and thinkers to Norfolk for conversation. Celebrating its fifth season this fall, the festival will gather 18 writers for discussions at the Norfolk Library on Sept. 20 and Oct. 3 through 5.
Jerome A. Cohen, author of the memoir “Eastward, Westward: A Lifein Law.”Haystack Book Festival
For example, “Never Take the Rule of Law for Granted: China and the Dissident,” will be held Saturday, Sept. 20, at 4 p.m. at the Norfolk Library. It brings together Jerome A. Cohen, author of “Eastward, Westward: A Life in Law,” and Mark Clifford, author of “The Troublemaker: How Jimmy Lai Became a Billionaire, Hong King’s Greatest Dissident, and China’s Most Feared Critic” in dialogue with journalist Richard Hornik to discuss the rule of law and China.
The Council on Foreign Relations stated, “Few Americans have done more than Jerome A. Cohen to advance the rule of law in East Asia. He established the study of Chinese law in the United States. An advocate for human rights, Cohen has been a scholar, teacher, lawyer, and activist for sixty years.”
Cohen, a professor at New York University School of Law and director of its U.S.-Asia Law Institute, revealed his long view on China: “We are now witnessing another extreme in the pendulum’s swing toward repression. Xi Jinping is likely to outlive me but ‘no life lives forever.’ There will eventually be another profound reaction to the current totalitarian era.”

In “The Troublemaker,” Clifford chronicles Lai’s life from child refugee to pro-democracy billionaire to his current imprisonment by the Chinese Communist Party. Clifford is president of the Committee for Freedom in Hong Kong Foundation, a Walter Bagehot Fellow at Columbia University, and holds a PhD in history from the University of Hong Kong. He was the former editor-in-chief of the South China Morning Post and The Standard (Hong Kong and Seoul).
