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.
LAKEVILLE — Rhys V. Bowen, 65, of Foxboro, Massachusetts, died unexpectedly in his sleep on Sept. 15, 2025. Rhys was born in Sharon, Connecticut, on April 9, 1960 to Anne H. Bowen and the late John G. Bowen. His brother, David, died in 1979.
Rhys grew up at The Hotchkiss School in Lakeville, where his father taught English. Attending Hotchkiss, Rhys excelled in academics and played soccer, basketball, and baseball. During these years, he also learned the challenges and joys of running, and continued to run at least 50 miles a week, until the day he died.
In 1982 after graduating summa cum laude from Harvard College, Rhys returned to Hotchkiss to teach biology, where he met his wife of 35 years, Rebecca (Becky) Snow. After two years of teaching, he worked at a research field site in Borneo, then went on to the University of California, Davis where he earned a PhD in Animal Behavior in 1995.
Rather than follow an academic tenure track, Rhys preferred the solitary focus of field ornithology, and he spent several decades researching the ecology of bird species in California and on Cape Cod and the Islands. Rhys believed passionately in supporting biodiversity through habitat preservation. His proudest achievements, therefore, came through his work for the Lakes Region Conservation Trust, in New Hampshire, where he served on committees and the Board of Trustees for twenty years, including three years as Chair.
Deeply intellectual and curious, Rhys learned Homeric Greek so he could read The Odyssey and The Iliad in their original language. An amateur Melville scholar, he would wax poetic about reading Moby-Dick for the umpteenth time.Rhys’s spirit was filled by the performing arts. Concerts by the Handel and Haydn Society and Boston Early Music Festival often brought tears to his eyes, while Boston Bluegrass Union shows delivered toe-tapping fidgetiness.
Rhys will be missed by his wife, Becky Snow, his mother, Anne Bowen, extended family, friends, and anyone who had the pleasure of knowing him.
A service will be held at The Hotchkiss School chapel on Saturday, Nov. 15, 2025 at 1 p.m..
In honor of Rhys’s memory, donations can be made to the Lakes Region Conservation Trust.

SHARON — On Sept. 27, Eliot Warren Brown was shot and killed at age 47 at his home in New Orleans, Louisiana, in a random act of violence by a young man in need of mental health services. Eliot was born and raised in Sharon, Connecticut, and attended Indian Mountain School and Concord Academy in Massachusetts. He graduated from the School of the Art Institute of Chicago. He and his wife Brooke moved to New Orleans to answer the call for help in the aftermath of Hurricane Katrina and fell in love with the city.
In addition to his wife Brooke, Eliot leaves behind his parents Malcolm and Louise Brown, his sisters Lucia (Thaddeus) and Carla (Ruairi), three nephews, and extended family and friends spread far and wide.
Normally at this point one might list some interests, but in Eliot’s case, it’s easier to list what he wasn’t interested in: watching sports.
Eliot made a living as a fine craftsman and carpenter, but at heart he was an artist. He was well versed in music, painting, literature, biking, travel, Mardi Gras costumes, poker, pranks, street performance and on and on and on.Having previously hiked the entire Camino de Santiago in Spain and Portugal, he recently achieved another dream of summiting the highest stratovolcano in North America.
Eliot’s creative ability was astounding. His creations were designed to bring joy to others. He didn’t seek recognition or praise, and a large part of his work was anonymous. Pieces of art would appear in the community, encouraging people to think, connect and enjoy.
From the precociously funny and determinedly defiant boy that grew up in the Northwest corner of Connecticut, Eliot grew into a brilliant, gentle souled, boundlessly creative, ever mischievous, perpetually scraggly, and astoundingly wise and caring man who made an indelible impact on those who were lucky to have him in their lives.
In honor of Eliot, please consider making donations to organizations that work to end gun violence, support the arts, or provide mental health services. A service will be held at the Congregational Church in Salisbury on Sunday Oct. 26 at 2 p.m.
SHARON — Randall “Randy” Osolin passed away on Sept. 25, 2025, at the age of 74. He was born on Feb. 6, 1951, in Sharon, Connecticut to the late Ramon (Sonny) and Barbara (Sandmeyer) Osolin.
He was a dedicated social worker, a natural athlete, a gentle friend of animals, an abiding parish verger, an inveterate reader, and an estimable friend and neighbor. He was a kind-hearted person whose greatest joy was in helping someone in need and sharing his time with his family and good friends.
He was the beloved husband of Karen LaChance Osolin; the loving brother of Bruce Osolin and the late Gail Osolin Leo; the devoted uncle of Kyle and Andrew Osolin and Taylor LaChance; the brother-in-law of Debra LaChance; and the cousin of Brenda Curran, Jay Pickering and Audra Salazar.
To honor Randy’s memory, do a good deed for another or send a donation to the Little Guild, 258 Sharon-Goshen Road, West Cornwall, CT 06796. The Kenny Funeral Home has care of arrangements.
