Co-founder of the Setauket Harbor Task Force, George Hoffman, said a few weeks ago, residents started reporting that as they were walking along West Meadow Beach they noticed a large amount of dead menhaden, a type of forage fish that is also known as a bunker fish. Others have also spotted the menhaden around Setauket and Port Jefferson harbors.

Hoffman said the task force reached out to local scientists, and a few residents contacted the New York State Department of Environmental Conservation as well. The DEC told residents that the die-off events were not unusual. The type of fish swim in large schools and are vulnerable to low dissolved oxygen. The DEC is collecting fish samples for analysis by Stony Brook University’s Marine Animal Disease Laboratory for further evaluation.

It’s the first time the task force has heard of a large die-off locally, Hoffman said. The task force tests the oxygen levels in local harbors regularly during the summer, and he said this year the levels have been good.

He said while the menhaden are not that large, measuring 8 or 9 inches, together they create an unwelcoming sight.

One of the people who noticed the dead menhaden and notified the task force was South Setauket resident Paul Feinberg, who visits West Meadow Beach regularly.

“My initial reaction to this sight back in early December was quite disturbing,” he said.

Bill Lucey, the soundkeeper from Connecticut-based Save the Sound, said the dead menhaden have been spotted along the Connecticut shoreline of the Long Island Sound, too. He has also heard reports of them washing up in the New York City and Hudson River areas.

Lucey said menhaden usually migrate earlier and they may have missed a migration cue due to warmer waters and a larger amount of plankton, which they eat, this year. However, once the temperatures dropped and the plankton died off, they may have faced problems, especially older fish that are less resilient. Normally around this time of year, the bunker fish can be found spawning along the shore of the Carolinas.

Another reason, Lucey said, that residents may be spotting an excess of dead menhaden is that there are more of them in general due to state-imposed fishing regulations. He said a friend of his was on the water fishing earlier this year when he felt a small earthquake in the Sound. His friend saw the menhaden jumping out of the water. Others have mentioned the increased number of bunkers to Lucey, too.

“One sailor said he hadn’t seen that many fish in 57 years,” he said.

Lucey said the increase in the amount of fish is a good thing. Hopefully the harvesting will be sustainable and the population will continue to increase as the bunker fish will attract predators such as humpback whales and bald eagles.

Residents “see a problem, but really it’s potentially a good sign that we have a huge robust population of the forage fish,” he said.

Local environmentalist John Turner agreed. He said with an increase again of menhaden they have been fueling a resurgence of the coastal ecosystem.

“It’s called a forage fish because it feeds and actually filters through the water, so it pulls algae and plankton out of the water, and it converts the microscopic plants that are in the oceans into animal protein,” Turner said. “Then that goes up the food chain again to the whales.”

He added that the menhaden can even be credited with an increase of bald eagles and ospreys in the area.

Lucey said when residents see dead menhaden on the beach to leave the carcasses as the fish will provide food for shoreline birds, which is especially important now that the temperatures are dipping, and there are less fish to be found in the water.

What does it take to monitor the health of your local waterways? For the people who month after month do just that, all it takes is a love for the place one lives.

The Setauket Harbor Task Force was one of the most active of the 22 groups involved with Save the Sound and its bay water recording initiative. The immense amount of work is taken up by a squad of volunteers, some of whom have been active during the May through October months of the last three years.

The Setauket Harbor Task Force originated as a way to monitor the health of what they considered the lone “orphaned” bay on the North Shore, but their activities eventually spread over the border into Port Jefferson as well. While the task force originated in 2015 to help maintain the local waterways’ wellbeing, in 2018 the group joined the United Water Study program under the EPA’s Long Island Sound Study, and since then has done monitoring in 10 different locations in Port Jeff and Setauket harbors.

Hoffman, of the task force, said they have dedicated much of their time and energy to the project, especially maintaining rigorous scientific standards. They have gone out in foggy mornings where you could barely see a few feet in front of the boat. Once, their craft’s engine stopped working, and they had to be towed back to harbor. There have been times their small craft has rolled in early morning swells, but they keep on going.

“With climate and environment, there’s so little that most people can do,” he said. “Every day you read about a new thing — ice shelves melting, whales being beached … I find when I talk to volunteers, it’s just being able to do something.”

Every participating organization must take readings of the water twice a month, no less than 10 days apart. Because monitoring must be performed three hours before sunrise, volunteers are up well before dawn, getting into the small craft and wading out into the harbors. Their recording instrument, a sonde meter that records all manor of water quality metrics, costs close to $20,000. 

Steve Antos, one of the task force board members, also owns Setauket Landscape Design. Though he and others in his group have lived in the area for decades, the idea of water quality has really taken a hold on many of its participants. Antos enjoys constructing rain gardens in his regular job, which are critical for preventing water runoff flowing from people’s yards down toward the Sound. 

“In the past, everyone tried to get their properties to drain onto the road … and eventually it just runs into our bays and takes all the pollution and dog waste with it,” Antos said. “A lot of it is way beyond our control, but whatever we can do, just little things, it all adds up.”

Before working with the task force, many of the 10 or so volunteers wouldn’t have known what most of the readings, from the chlorophyll levels or turbidity (the water clarity) meant, but now have become a kind of citizen scientist, able to comprehend measurements using a very technical device. Their backgrounds range from a retired veterinarian to retired teachers, but what brings them together is their long time proximity to the bays and waterways of the North Shore. It’s what drove them to want to make sure the water was being maintained.

Tom Lyon, of Mount Sinai, and Mark Smith, of East Setauket, are the boat captains, and have lent their experience and water crafts to the project. They are small runabouts, one an 18-foot and the other 16. 

Nancy Goldstein, herself a trained scuba diver, got into the project thanks to a friend and has been active for three years. 

“I took marine biology in high school, but I’m totally not a scientist,” Goldstein said. “I care about the earth, and the marine — it’s all one.”

Bert Conover, a retired veterinarian from Port Jeff, said he has always been on the water “from Delaware River to Ocean City.” Long ago, he majored in chemistry and biology, but went to grad school for zoology and then went on to veterinarian school. 

“Now that I’m retired it gives me a chance to give back,” he said. “And hopefully the data will redirect how to approach a healthy harbor.”

Alice Leser has lived in Stony Brook for 49 years, and is a life-long Long Islander. She has taught programs about Long Island waters as a teacher and alongside fellow environmentalists at the Long Island Museum. When three years ago the task force offered her a training program at the Village Center, she snapped up the opportunity.

“I’ve been surrounded by water my entire life,” she said. “I’ve canoeed all the rivers, and I’ve taught programs about Long Island waters, so I really care about the purity of the water.”

Laurie Vetere, the fellow co-founder of the task force, said they have not had anyone drop out in three years.

“When we first started this program, we found that we had more volunteers than we needed,” Vetere said. “People are attracted to the water.”

Hoffman agreed, saying there is something about Long Islanders and their connection to their coasts.

“Long Islanders are coastal people,” he said. “I think what keeps us on Long Island is we all have a love for the water.”

A new report by a regional environmental nonprofit says a little under half of all bays on either side of the Long Island Sound were given a poor-to-failing grade. It’s a continuing problem, but more and more local groups are stepping up to dedicate their time and energy to trying to maintain the water as a strong habitat.

At a press conference Tuesday, Oct. 6, Save the Sound, a Connecticut-based environmental nonprofit funded by a U.S. Environmental Protection Agency grant, released its biennial 2020 Long Island Sound Report Card that described the general health of 50 bays from Long Island and Connecticut based on the previous year’s data.

Officials and experts revealed that, of those monitored, Suffolk County North Shore harbors were largely better off than those in Connecticut, but several still had issues. Port Jefferson, at least the outer and middle portions of the harbor, was ranked in the top 10 most healthy, with experts saying it most likely has to do with how well the harbor flushes daily.

Meanwhile sites like Northport and Centerport harbors were ranked C- and C respectively. Northport Harbor received a F grade for its excess of chlorophyll, a measurement of how much microalgae is in the water, and its low level of dissolved oxygen, an important factor for the health of fish. Centerport had similar difficulties, but also had issues of excessive seaweed accumulation.

Perhaps the most concerning of North Shore Suffolk County’s waterways was the innermost part of Cold Spring Harbor which received F grades in chlorophyll, seaweed and dissolved oxygen. 

U.S. Reps. Tom Suozzi (D-NY3) and Lee Zeldin (R-NY1) were both present to offer their support of bipartisan funding for this and future studies as well as initiatives to keep local bays clean. Suozzi said in the past four years, the Long Island Sound Caucus has extended the EPA Long Island Sound program to 2023 and increased the $4 million appropriated to the Sound to $21 million. The House has already passed a bill to up that to $30 million, but has not yet been taken up by the Senate.

Zeldin said the low grades of so many bays only emphasizes the need for more federal funding for further studies and additional relief. 

“Working across the aisle and across the Sound, we’ve made great progress in preserving this critical waterway, but with nearly half of the waterways measured in this report as receiving a D grade or below, there’s still work to do,” he said. 

George Hoffman, a co-founder of the Setauket Harbor Task Force that monitors Port Jeff, also acknowledged a great deal of why the bay has done comparatively well is because of its flushing capacity. Another factor, he said, may be the hundreds of thousands of oysters and shellfish the Town of Brookhaven seeds into the bay. The shellfish do a great job of filtering organic particulates from the water.

Save The Sound’s Unified Water Study program includes 22 organizations covering 50 harbors on both sides of the waterway. Monitoring begins in May and ends in October. The study also looks at the general health state of the Sound itself. It’s long been clear that the closer one is to New York City, the less healthy the water is. The Western Narrows portion of the Sound received an F grade on all marks, while the Eastern Narrows, which runs from Northport to the edge of Hempstead Bay, received a C grade overall. Areas to the east were reported as much healthier in general.

Jamie Vaudrey, an assistant research professor of marine science at the University of Connecticut, said likely the biggest factor for the health of bays in a modern environment is how well the water flushes in and out of the harbor. Water like that trapped into the southernmost tip of Cold Spring Harbor is more impacted by any real increase in nitrogen.

“They just have this large nitrogen burden coming in that’s not being flushed out,” she said. “In systems like that, really pushing down that nitrogen load is important.”

Nitrogen has been called public enemy No. 1 for coastal waters as it’s the leading cause of hypoxia, namely low or depleted oxygen causing major problems for marine life. This can cause fish or other sea creatures to die off and lead to an excess of seaweed or algae. Some of these algal blooms have even been dangerous to animals or humans.

Though Port Jefferson Harbor’s general health was rated high, it too has experienced its share of dangerous algal blooms, including a so-called rust tide back in 2018. Though this specific bloom doesn’t present a threat to human beings, it kills fish quite rapidly. Those who study water quality have become very concerned with how often these blooms have appeared since the early 2000s.

For some of the struggling bays in the Town of Huntington, New York State Sen. Jim Gaughran (D-Northport) called for a funding stream from the federal government on down that can really start to make a dent in Suffolk County’s lack of sewage treatment facilities and get the ball rolling on nitrogen-reducing septic systems, which individually can cost a homeowner $10,000 to $15,000 apiece without government funding. 

“People can’t do that on their own — we need tax credits, we need funding,” he said.

A few concerned local citizens are taking the health of the Long Island Sound into their own hands.

From May through October, nonprofit Save the Sound, an organization dedicated to the health of the body of water, will continue its Unified Water Study: Long Island Sound Embayment Research program for a second year, testing the water conditions in the Sound’s bays and harbors. The program operates through a grant from the Environmental Protection Agency and using a corps of trained testers, called Sound Sleuths, who volunteered to measure dissolved oxygen, chlorophyll, temperature, salinity and water clarity out on the water at dawn twice monthly during the six-month period. Port Jefferson Harbor will be tested by members of Setauket Harbor Task Force, a nonprofit group founded in 2014 to monitor and advocate for the health of the harbor, who volunteered to serve as Sound Sleuths. Setauket Harbor lies within the greater Port Jefferson Harbor Complex.

Task force members George and Maria Hoffman, Laurie Vetere and volunteer Tom Lyon set out in a roughly 15-foot-long motorboat May 25 at 6:30 a.m. to test 10 randomly preselected specific locations in Port Jeff Harbor, with testing equipment provided by Save the Sound, for the second round of research set to take place this spring and summer. The testing needs to be completed within three hours of sunrise in order to ascertain the most valid data possible, according to George Hoffman.

“I know a lot of people are familiar with water testing, but it’s usually about pathogens,” Hoffman said, which often is examined to determine the safety of swimming or eating shellfish. Testing for water chemistry will reveal more about the health of marine life in the harbor. Hoffman discussed the task force’s plans for testing during a May 6 meeting of the Port Jefferson Harbor advisory commission, a group overseen by the Town of Brookhaven that includes representation from all nearby municipalities and also takes up the responsibility of monitoring harbor health.

“We’re not testing for pathogens,” he said. “This is really about harbor health and chemistry.”

Hoffman said while out on the boat May 25 the group tested each of the 10 sites twice — once about a half a meter off the bottom of the harbor and once a half a meter from the surface of the water, using an instrument called a sonde, which is attached to a long cable and submerged in the water. Hoffman said the instrument costs about $30,000.

“That gives us a pretty good idea of what’s happening in the water column,” he said.

Save the Sound explained the importance of testing the chemistry of bays and harbors within the Sound in a May 16 press release announcing the year 2 testing kickoff.

“More than a decade of federally funded monitoring of the open Sound has documented the destructive impact of nitrogen pollution — including algae blooms, red tides, loss of tidal marshes and fish die-offs — and the incremental improvements brought about by wastewater treatment plant upgrades,” the release said. “Conditions in the bays and harbors — where much of the public comes into contact with the Sound — can be different from conditions in the open waters. More testing on bays and harbors is needed to judge the effect of nitrogen on these waterways and what action is needed to restore them to vibrant life.”

Suffolk County Legislator Kara Hahn (D-Setauket), who also chairs the county’s Environment, Planning and Agriculture committee, said while the county has taken up the fight in finding ways to reduce the amount of nitrogen in Long Island’s waters, having dedicated citizens also keeping an eye is an asset.

“That’s critical, these kind of community efforts to protect water bodies,” she said. “It’s special.”

Results of the study will be published in future editions of Save the Sound’s Long Island Sound Report Card.

Participants to create water report card for harbors and bays of the Long Island Sound

There’s a team collaboration happening across Long Island to ensure the Long Island Sound’s water is as healthy as possible.

Save the Sound, a nonprofit organization based out of Connecticut, is working with local groups and volunteers to create a water quality report card for the Sound’s bays and harbors, in an effort to increase available data for residents to have access to information on the health of the Sound.

Monitoring of the open Sound, the areas of the water body beyond bays and harbors, in the last decade has revealed the increasing presence of nitrogen pollution — which leads to algae blooms, red tides, loss of tidal marshes and fish die-offs — and the incremental improvements brought about by wastewater treatment plant upgrades. But researchers have acknowledged that results found in the open Sound may not reflect conditions in the bays and harbors, where a large part of the public comes in contact with the Sound.

In May, Save the Sound started conducting the Unified Water Study in 24 sites across the Sound, and participants will be testing the water twice a month through October, looking at dissolved oxygen levels, temperature, dissolved salt levels, water quality and more.

Organizers gathered at Huntington Harbor in Halestie to conduct a test Tuesday, June 13, and explained why the report card is so important for the future of bays and harbors across Long Island.

“The Long Island Sound Funders Collaborative funded a report card for the sound, with the first one coming out in 2015, and through the report card process we realized that most of the data we had collected to talk about water quality and the health of the sound was for the open Sound,” Tracy Brown, director of Save the Sound said at the harbor. “And when we published the report card and showed the scores of water quality but we didn’t go into all the bays and harbors the public said, ‘well how about my harbor, how about my cove?’ The bays, harbors and coves are their own unique ecosystems. So we realized we had a data gap.”

Brown said certain groups have been doing their own studies in smaller areas but nothing uniform to have a comparative level. The report card focuses on the ecological health, not bacteria levels and risk of contamination for humans entering the water, but rather the creatures living in the water 24/7.

“The pollutant of concern is nitrogen,” Brown said. “This study was designed to get into all 116 little bays, harbors and coves that encircle the sound, and our goal is to get into each of them taking the exact same measurements for an assessment to say which of the bays and harbors are not handling the nutrient input well, which ones are really suffering from nutrient pollution and then we can direct conservation resources.”

Brown said one of the leading causes of increased nitrogen is contamination from the septic systems, as urine has high levels of nitrogen. She said efforts like Suffolk County Executive Steve Bellone’s (D) initiatives to improve groundwater and limit nitrogen pollution are a step in the right direction.

“Nitrogen pollution has been identified as the single greatest threat to water quality, but for the first time in decades, we have a historic opportunity to turn the tide in our effort to reclaim our waters,” Bellone said in a statement when announcing countywide nitrogen-reducing initiatives for homeowners.

Brown reiterated some of the dangers of high levels of nitrogen.

“High levels of nitrogen feed growth, creating algal blooms, and when the algal blooms die they suck the oxygen out of the water in that decay process so you create these low oxygen zones,” she said.

Low oxygen levels mean finfish and shellfish can’t live in the area, and high nitrogen levels also lead to the destruction of coastal wetlands, which not only serve as a habitat for animals but also are a defense for homes from destructive storms. Brown also said high nitrogen levels are being linked to high acidification levels, which prevent shellfish from forming their shells and reduce the population’s ability to reproduce.

About a year ago Peter Janow, a Cold Spring Harbor resident, got in touch with Save the Sound, after hearing about their efforts, and extended an offer to help if they needed any hands for the Huntington and Northport bay areas.

“Once they created the Uniform Water Study they got in contact with me and asked if I could help out and I said ‘absolutely brother,’” Janow said of how he first got involved. He eventually ended up joining more volunteers to work on the area together. He said he was motivated to get involved to both make a difference and help become a stronger part of his community.

“Most folks, especially on Long Island we’re surrounded by gorgeous scenes, the harbors, all the water sports,” Janow said. “We [the volunteers] share in the duties, and the role is covering the greater Huntington and Northport complexes including Lloyd Harbor, Huntington Harbor, Centerport Harbor, Northport Harbor and Duck Island Harbor, and each one of those areas has its own qualities. We have a total of 25 specific locations we’re testing water samples from.”

Janow said he and the others divide the areas up into two different days, spending about three hours each day testing water samples.

The combined efforts are for the benefit of all Long Islanders, and residents can help without getting on the water themselves.

“We really hope the public will see the significance,” Brown said. “If you want a better grade, you need to take care of your wastewater, and reduce your lawn fertilizer. The science community has identified nitrogen as enemy number one to the Long Island Sound, and the philanthropic community said, ‘what can we do,’ and then they reached out to regional groups to execute their vision, and then we’ve reached out to local groups for help. That’s what’s so interesting about this study — the collaboration.”

The collaborative effort is far from over. Brown said there is still a need for more volunteers to cover areas east of Huntington, including areas in the towns of Smithtown and Brookhaven, especially near the Nissequogue River and Port Jefferson Harbor.

This effort travels all the way to Connecticut, and one science teacher at a town in Dover took the initiative to volunteer himself and his Advanced Placement students to help contribute.

“One of the things that makes it possible for groups to organize to participate in this study even if they’re not already a group is that we provide the equipment, we provide the training, we provide the standard operating procedures and Save the Sound is available to help them get off the ground and make sure they succeed,” Brown said. “If we’re going to reach all 116 systems around the Sound that we want to reach, we’re going to need more groups. We’re going to need new groups that don’t exist yet to organize around the study and ask if anyone is in their bay or harbor yet.”

Anyone interested in getting involved with Save the Sound should reach out to Peter Linderoth, the Save the Sound water quality manager at [email protected].

The Setauket Harbor Task Force gave an update recently to the community about its ongoing efforts to protect Setauket Harbor and the surrounding shoreline. Approximately 70 people came to the task force’s third annual meeting, held at the Setauket Neighborhood House April 19.

“How Clean Is Setauket Harbor?” was the title of a talk given at the meeting. The goal was to give people the opportunity to learn about the health of the harbor and find out what the task force is doing about it.

Setauket residents who noticed the harbor was struggling founded the volunteer, nonprofit organization in 2014, said task force board trustee George Hoffman at the meeting.

“Sometimes the water looked cloudy,” Hoffman said. “There were a lot of algae blooms. We knew that nobody was really speaking out for Setauket Harbor.”

Now the task force wants to partner with the organization Save the Sound, Hoffman said, to create a citizen-scientist, water quality monitoring program in Setauket Harbor. Local volunteers, trained by Save the Sound personnel, would start taking water samples next spring and work through October.

Peter Linderoth, water quality program director for Save the Sound, spoke at the meeting about his organization’s Citizen Science Unified Water Testing program to begin this summer in some Long Island Sound harbors and bays. Twice a month, he said, volunteers will record precipitation data; look at water clarity, seaweed and eelgrass; and track levels of dissolved oxygen, chlorophyll, salinity and temperature.

The Setauket program would be similar, Hoffman said in a recent phone interview. He said the cost of training volunteers would be covered by the Long Island Sound Funders Collaborative, a group of funding organizations that pool their resources to help protect the Sound. The water quality monitoring equipment will be provided through a grant Save the Sound obtained from the U.S. Environmental Protection Agency, Hoffman said.

About a dozen volunteers have already signed up to monitor water quality in Setauket Harbor, and the task force is looking for more, Hoffman said.

The April task force meeting also addressed a DNA analysis of pathogens in Setauket Harbor. The harbor is closed to shell fishing due to high numbers of disease-causing bacteria associated with human and animal waste.

Lorne Brousseau, marine director for Cornell Cooperative Extension, said the six-week study — commissioned by Brookhaven Town and conducted last fall — revealed that “birds seemed to have the biggest impact” on numbers of coliform in the water, with Canada geese being the worst offenders. The second highest source, Brousseau said, was “human-derived fecal coliform.”

“Where that came from, we’re not sure,” he said. “It could be boat discharge or septic systems.”

Brousseau also said there was a “low proportion of domestic animal fecal coliform – a few dogs and one horse.”

A man in the audience asked if it were possible to determine what percentage each source contributed to the total fecal coliform in the harbor. Brousseau said many more samples, taken from the water many more times, would have to be obtained to come up with percentages.

“It’s cost-prohibitive and time-prohibitive,” he said.

Brousseau also said fecal coliform in Setauket Harbor increases, and water quality deteriorates, after a rainfall.

“After it rains, the numbers triple, quadruple, sometimes more,” he said.

Task force chairperson Laurie Vetere also spoke at the meeting. She said funds from a $1 million state grant to fund water quality improvement in Setauket Harbor and its watershed are expected to become available soon. The grant, announced last fall, was secured for Brookhaven Town by Senator John Flanagan (R-East Northport), working with Assemblyman Steve Englebright (D-Setauket.)

The town will use the funds to remove accumulated silt at the entrance to the harbor, renovate the town dock on Shore Road, and continue managing storm water, Vetere said. The grant “was a huge deal, and we’re hoping that money comes in sooner rather than later,” she said. She also said Brookhaven Town employees have recently been cleaning brush and debris from the Setauket pond park next to the Se-Port Deli.

Vetere said in a recent phone interview that the DNA pathogen analysis was an important source of baseline data.

“Even in dry weather, there have been very high levels of bacteria in the harbor,” she said. “We’re not really sure where that’s coming from, but we’re going to be addressing it.”

Vetere also said the Setauket Harbor Task Force will seek ways to work with Suffolk County on its new Septic Improvement Program, a grant and loan program to help homeowners replace outdated septic tanks with nitrogen-reducing septic systems.

Vetere said storm water runoff is an issue for Setauket Harbor. Last November, she said, five task force members piled into a car and drove around the harbor “and just watched how storm water was coming down the streets.” The task force is exploring if it would be effective for homeowners around the harbor to plant passive rain gardens, Vetere said, because the gardens soak up storm water and absorb pollutants.

The Setauket Harbor Task Force will hold its annual Harbor Day — environmental exhibits, kayaking and paddleboard lessons, entertainment and other activities — Sept. 23 at the town dock on Shore Road.
