“If we wait five years, we will be able to walk across the river if it’s left
unchecked.” — Bob Petzold, president of Petzold’s Marine Center, on the urgency of halting hydrilla’s rampant spread.
This is the second of a series about invasive aquatic hydrilla and its growing threat to waterbodies and communities in Northwest Connecticut.
CHESTER, Conn. — Bob Petzold has spent the past few summers mowing his marina’s boat slips.
Thick, verdant green mats of notoriously troublesome hydrilla have made it impossible for vessels to enter or exit the channel unless he and his crew mechanically chop, gather and haul away massive piles of the invasive weed, which has clogged the Chester Boat Basin, one of two marinas he owns and operates on the Connecticut River.
Petzold knows that in doing so, he raises the risk of spreading hydrilla fragments that will drift away and repopulate elsewhere. But he has little choice, he said, if his four-generation, family-owned and operated business is to remain afloat.
“It’s a necessary evil,” he said. And an expensive one at that.
“We spend thousands of dollars on outside contractors and we have our own staff remediating it just to keep the channel open,” Petzold explained during an early September visit to his marina.
“When the water is clear, you can almost watch the hydrilla grow. If we wait five years, we will be able to walk across the river if it’s left unchecked.”

The strain of hydrilla in the Connecticut River has been an ongoing concern since its discovery in 2016. It is considered genetically distinct from other known hydrilla populations in the world, and as such, there is limited information available to aid in the development of management strategies to limit its explosive spread.
Kayaks can’t pass through it. Boat motors get tangled by its long strands and stall. Coveted fishing holes have been abandoned by anglers, and swimmers won’t swim in it. Scientists are also addressing concerns about hydrilla’s threat to the ecosystem, including osprey and bald eagles. They fear that the Connecticut River strain harbors cyanobacteria, which produces a neurotoxin deadly to birds of prey.
Rhea Drozenko, river steward for the Connecticut River Conservancy, pointed to the Mattabesset River as an example of hydrilla’s explosive nature. “It created this huge mat, and some native plants couldn’t stand a chance. It created a sea of hydrilla.”
Fortunately for Petzold, and others who own businesses or real estate, enjoy recreational activities or cherish the 200-mile-long river’s aesthetics and ecology, hope is on the horizon.
Petzold’s two marinas, Chester Boat Basin and Portland Boat Works, are among five sites in the Connecticut River Watershed selected for testing of aquatic herbicides this summer as part of an ongoing hydrilla research project by the U.S. Army Corps of Engineers (USACE).
Other test sites include Chapman Pond in East Haddam, Keeney Cove in Glastonbury and Selden Cove in Lyme.
Scientists hope to reduce and control hydrilla, while protecting plants, fish and the long-term health of the river, as well as its $1 billion-plus contribution to Connecticut’s economy.
The results of that research could also bring a sigh of relief inland, where 10 lakes, so far, have been identified as hosts to hydrilla, which is spread between bodies of water primarily by unsuspecting boat owners.
East Twin Lake in Salisbury was the first lake outside of the Connecticut River watershed to identify an infestation late last summer. That number is expected to rise once the Connecticut Agricultural Experiment Station (CAES) concludes its planned inspections of every state-owned boat launch throughout Connecticut.

In 2021, Sen. Richard Blumenthal (D-Conn.), announced that he is leading an effort to secure $100 million over four years in federal funding for a multistate effort to control hydrilla in the Connecticut River Watershed, and in June, he announced $5 million in federal funding for the USACE demonstration project.
“Senator Blumenthal was here. He pledged his support in getting government funding for this continual battle,” noted Petzold, who referred to hydrilla as “the biggest threat beyond our control” in the nearly 80-year history of his family business.
The funds will also support other goals including preventing hydrilla from spreading into coves, tributaries and inland waters, improving surveillance and detecting new infestations early and responding quickly to control and eradicate new infestations.
In addition, the Connecticut Department of Energy and Environmental Protection (DEEP), through the State Aquatic Invasive Species (AIS) Grant Program, made $500,000 available to municipalities, state agencies and nonprofit organizations to reduce impacts of aquatic species, including hydrilla, on inland waters.
Connecticut awarded approximately $952,700 to 46 projects statewide during the first three years of the AIS Grant Program.
As stakeholders await the results of the USACE’s demonstration project, already there are encouraging signs.
Petzold pointed to the gently rippling water surrounding the boat basin, which he said had not been that clear during peak boating season for several years. Around the slips, strands of sickly-looking hydrilla floated among dead leaves, victims of herbicidal dosing.
He credited the bipartisan support of lawmakers on the local, state and federal level for going “above and beyond” in supporting and communicating with stakeholders.
“In my mind, it’s made a world of difference. We’ll see what the test studies reveal, but it seems like it is doing the trick here, at least in the basin,” said the marina owner, who credited DEEP and USACE for working together effectively and keeping stakeholders in the loop and respond to their concerns.
“At this point I guess there’s no cure for it, but we have to figure out a way to stop it from spreading and growing as best we can.”
Beth Rye of Chester, who owns two vessels, a 20-foot Grady-White and 35-foot Viking, was ecstatic about being able to navigate in and out of the slips without her boats’ props getting snarled in hydrilla. “It’s gone!” she announced with glee.
Relief for some raises red flags for others, noted Drozenko, particularly when aquatic herbicides are involved.
“There has been a lot of concern about the use of herbicidal treatments, especially in very fragile, ecologically sensitive zones.”
Lakes and ponds, she said, are easier than flowing rivers to treat, as they are more contained and especially if the infestation is caught early, as in Salisbury’s East Twin Lake.
“Whereas if hydrilla moves into the Housatonic River,” the river steward cautioned, ‘it will have the same impact as in our river.”
Coming next: What’s at stake for Salisbury’s six lakes in 2025 and beyond.
Travel league baseball came to Torrington Thursday, June 26, when the Berkshire Bears Select Team played the Connecticut Moose 18U squad. The Moose won 6-4 in a back-and-forth game. Two players on the Bears play varsity ball at Housatonic Valley Regional High School: shortstop Anthony Foley and first baseman Wes Allyn. Foley went 1-for-3 at bat with an RBI in the game at Fuessenich Park.

Uncommon books at the intersection of art and literature.
Pearson first encountered the world of alternative publications — magazines filled with experimental writing, artworks in the form of a book, and samizdat literature — as a young writer living in Berlin just before The Wall came down in 1989. Later, in New York City, she spent a great deal of time with artists “who were always making and assembling, whose continuous art-making made the thin membrane between art and life even more porous,” she explained.
Pearson traces the idea of publishing to a 2001 exhibition of artist-poet Joe Brainard. That show led to “The Nancy Book,” Siglio’s debut title in 2008, and she’s never looked back. The book contains over fifty full-page reproductions of Brainard’s dazzlingly accomplished and witty drawings of the cartoon strip character, Nancy. It includes essays and contributions by Robert Creeley, Ann Lauterbach, Frank O’Hara, Ron Padgett, and other poets of great renown, all thrilled to celebrate and remember Brainard (sometimes called “a poet’s artist”) who died of AIDS in 1994. Pearson said, ‘My first project with Brainard was such a good experience, I kept going. “
Since then, Pearson, the sole proprietor of Siglio, has designed, edited, and published over 40 books and other printed editions. Her books are characterized by unexpected juxtapositions of texts and images and collage-like assemblages, as well as for carefully designed and gorgeously printed volumes. Her list includes many “rediscoveries” of unpublished manuscripts and little-known publications. At the same time, she has commissioned new work from an impressive array of artists and writers such as Christian Marclay, Sophie Calle and Cecilia Vicinua among others.

Though most Siglio books feature work by artists and writers from the 1960s to today, one standout— “Tantra Song” (2011) — showcases vibrant 17th-century Indian tantric paintings collected by poet-ethnographer Franck André Jammes, their modernist feel echoing Hilma af Klint or Brice Marden. Siglio also frequently draws on the spirit of the Fluxus movement, reissuing works by figures like John Cage and Ray Johnson with editions that honor their playful, ephemeral, and poetic origins.
Siglio also excels at photo-narratives rooted in highly specific, often eccentric concepts. “Memory” (2020), by avant-garde writer Bernadette Mayer, reproduces her journal and daily rolls of 35mm film from a month in the Berkshires in 1971, capturing the texture of each day. “Call and Response” (2022), created during COVID lockdown by composer and visual artist Christian Marclay, pairs his photographs of London’s quieted streets with musical scores composed in reply by his friend Bruce Beresford—each image in dialogue with sound.
Siglio books are sold through it’s website (sigliopress.com), as well as museum or specialty bookshops. (The Lenox Bookstore represents a number of Siglio books; the newly opened Lakeville Books & Stationery has copies of “Tantra Song.”) In all cases, Pearson strives to make “two or three degrees of connection” with each book buyer, including a “special gift” — often a piece of printed ephemera — with each purchase.
