Raritan River: Imagining Past, Present, Future with AI

The Raritan River is a constantly changing feature of the landscape of New Jersey. As a tidal river, it changes daily. As a geologic feature, it changes its channel with erosion and accretion. The watershed that drains into the river continues to develop, changing the stormwater runoff that fuels the river as engineering simultaneously mitigates and worsens the impacts. Thinking of the Raritan as a static or fixed feature ignores its realities.

In this video clip, Rutgers Landscape Architecture Graduate School student Ana Maria Oliynyk works with AI to mine historic images of the Raritan River at New Brunswick, and engages AI to imagine the future for the Raritan.

From Land to Water: Water health in time of climate change, Teacher Professional Development with the LRWP

What we do on land does not stay on land. The choices we make on what we do on our property can impact the waters nearby as rain and runoff pick-up and move pollutants from their point of origin to our waterways. In a time of climate change when precipitation is highly variable these pollutants are more likely to affect our local and regional water quality.

Join the LRWP for two Teacher Professional Development Workshops, offered in partnership with the New Jersey Climate Change Learning Collaborative and the New Jersey Department of Education.

On both Monday June 23 and Tuesday August 12 we will tour New Brunswick infrastructure and landscape and take a boat trip on the Raritan River to learn more about how we monitor water quality in general and pathogen monitoring more specifically, and about solutions to divert the pollutants from our waterways. These full-day workshops will be followed up with a webinar (August 14th, 4PM EDT) to explore instructional resources related to the Lower Raritan watershed, and water quality monitoring.

Raritan Pathogens Results 6.17.25

By Danielle Bongiovanni and J.M. Meyer

Out of respect for Juneteenth, the fifth Pathogen Monitoring session occured on Tuesday, June 17 instead of a Thursday. Each week during the summer, from May to October, the Lower Raritan Watershed Partnership and Rutgers Cooperative Extension of Middlesex County run a volunteer-based monitoring program along the Raritan River. We collect water quality samples at six non-bathing public access beach sites, provide our samples to the Interstate Environmental Commission for analysis in their laboratory, and report the results to the public. Our mission is to share this data with the community and partners to ensure the safe use of the Raritan river for all.

Our lab results for water quality samples taken on Tuesday, June 17, 2025 show Enterococcus bacteria levels exceeding the EPA federal water quality standard of 104 cfu/100mL at two of our monitoring sites this week. Problem sites are indicated by red frowns on the map and chart which includes: Riverside Park (Piscataway) and 2nd Street Park (Perth Amboy). Green smiles on the chart and map indicate the sites with bacteria levels safe for recreation, and include the following: Rutgers Boathouse (New Brunswick), Raritan Bay Waterfront Park (South Amboy), Ken Buchanan Waterfront Park (Sayreville), and Edison Boat Launch (Edison Township).

Pathogens/Enterococci levels are used as indicators of the possible presence of disease-causing bacteria in recreational waters. Such pathogens may pose health risks to people coming in primary contact with the water (touching) through recreational activities like fishing, kayaking or swimming in a water body. Possible sources of bacteria include Combined Sewer Overflows (CSOs), improperly functioning wastewater treatment plants, stormwater runoff, leaking septic systems, animal carcasses, and runoff from manure storage areas.

Our goal in reporting these results is to give residents a better understanding of the potential health risks related to primary contact during water-based recreation. If you are planning on recreating on the Raritan this weekend, make sure to stay safe and wash up after any activities!

Raritan Pathogens Results 6.12.25

by Danielle Bongiovanni and J.M. Meyer

Thursday, June 12th marked the fourth week of Pathogen Monitoring and one week since a pile of feces, sanitary products, and sediment was discovered a few hundred feet from the Robert N. Wilentz Elementary School’s playground. Every Thursday during the summer, from May to October, the Lower Raritan Watershed Partnership and Rutgers Cooperative Extension of Middlesex County run a volunteer-based monitoring program along the Raritan River. We collect water quality samples at six non-bathing public access beach sites, provide our samples to the Interstate Environmental Commission for analysis in their laboratory, and report the results to the public on Friday afternoons. Our mission is to share this data with the community and partners to ensure the safe use of the Raritan river for all.

Our lab results for water quality samples taken on Thursday June 12, 2025 show Enterococcus bacteria levels exceeding the EPA federal water quality standard of 104 cfu/100mL at three of our monitoring sites this week.

Green Brook Cleanest Yet After 5th Annual Multi-Site Clean-Up

By Danielle Bongiovanni, LRWP 2025 Science Communication Intern

On Saturday, May 10, dozens of volunteers worked together to fill nearly 100 garbage bags with litter removed from the Green Brook. The Lower Raritan Watershed Partnership (LRWP) led the fifth annual multi-site clean-up alongside the Americorps New Jersey Watershed Ambassadors (NJWA), the Union & Somerset County Clean Communities Programs, the Mayor’s Alliance for a Cleaner Green Brook Waterway, and the Central Jersey Stream Team. The sites stretched across eight participating municipalities: Dunellen, Green Brook, Middlesex Township, Plainfield, South Plainfield, Watchung, Scotch Plains, and Bound Brook.

Volunteers originated from beyond those municipalities’ borders, inspired by how all watersheds are connected and impact each other. Piscataway resident David Dunham has participated in clean-ups with his son for nearly a decade, several of which focused on the Green Brook. Repeat visits have yielded visible progress.

“In general, [the Green Brook] was in much better shape than some of the other times we’ve been over here. It’s nice to come back to the same spot and be able to compare,” Dunham said. “It’s a good sign, we’re heading in the right direction.”

Still, volunteers picked up plenty of trash. Dunham recounted collecting “small bottles, cans, wrappers that had come off of some bottle at some point. Nothing too out of the ordinary until we got to the very end, and then we found a kitchen sink.”

Other notable items collected throughout the day included tires, stereo equipment, mattresses, and a wheelbarrow. The majority of trash present consisted of everyday litter such as plastic bottles, beer cans, and broken glass — little items discarded without thought for how quickly they pile up.

Volunteers found a variety of macroinvertebrates amidst the trash, and the seven Watershed Ambassadors in attendance eagerly provided identification. At McCoy Park in Dunellen, Kaitlyn Pinto and Emilie Wigchers, who normally cover Watershed Management Areas #7 (Arthur Kill) and #4 (Lower Passaic, Saddle) respectively, pointed out clam shells, worms, snail eggs, and midge fly larvae.

The Green Brook’s ecosystem is dominated by pollution-tolerant organisms. Pinto and Wigchers note their presence to determine the brook could be healthier. Watershed Ambassadors promote environmental stewardship with the hope of making areas like the Green Brook suitable for pollution-sensitive macroinvertebrates like gilled snails or mayflies.

“This is a great partnership between Watershed Ambassadors and LRWP, and it’s not just the clean-up. They do a bunch of other stuff too, and we do fun stuff like the litter trap monitoring and the eel monitoring and all these cool things. It all ties into that theme of protecting water quality in the state, so it’s a really good connection to have,” Pinto said.

The theme of collaboration in pursuit of healthier watersheds was strong, with members of organizations with similar missions coming out to support the LRWP. Mark Lesko, founder of the Highland Park Ecology and Environmental Group (HPEEG), made time to participate despite running clean-ups for the HPEEG on the first and third Saturdays of each month.

Lesko reflected on the impromptu clean-up that cemented his dedication to environmental stewardship. “My first one was more than a decade ago. My daughter and I were in Johnson park looking for salamanders in a stream, and she said, ‘Daddy, look at all the trash…’ So we started cleaning it and all these kids that were at picnics came down and started cleaning it with us, and that day, I started my group,” he said.

The Green Brook clean-up ran from 9:30am – 12:00pm and was followed by a public demonstration of the Bandalong Bandit Litter Trap and the final eel monitoring session of the migratory season. Dunellen Mayor Jason F. Cilento, who participated in the clean-up, thanked the Dunellen Department of Public Works for routinely emptying the litter trap.

Like Dunham, Cilento noted how less trash is collected at each clean-up, indicating a cultural shift away from littering and toward respecting natural spaces. Cilento praised the other participating municipalities and organizations for their roles in making visible progress protecting a watershed dear to his childhood. “I grew up playing in these woods and this water and everything,” he said.

Although no glass eels or elvers were observed at the monitoring session, the crowd witnessed a tessellated darter and a variety of macroinvertebrates emerge from the eel mop. Volunteers went home tired and in need of showers, but satisfied from a day of good hard work.

Reading the River

Essay and photos by Joe Mish

At sixty strokes a minute, the paddle leaves a linear series of isolated, expanding ripples, lingering on the water’s surface, appearing like the tracks of a rabbit running in the snow. Photo by Bill Haduch

The low concrete dam spanned the shallow river to create a constant water supply for a long gone 19th century grist mill. Above the dam a placid lake was formed, its surface appeared static and reflective to disguise the current as the determined river flowed from highlands to sea level. The dam caused the river to pause its downstream journey as it pondered its escape from the impoundment. It first attempted to expand its breadth to go around the obstacle. Failing that, the river began to overflow the dam.  The water flowing over the dam was now energized by its escape, and enlivened by the infusion of oxygen from its precipitous fall. The resulting white water was a sign of turbulence and the aeration reduces the density of the water making objects less buoyant.  As the water fell upon itself, the weight of the falling water created a void, filled in by downstream water flowing upstream, to form a horizontal current, spinning parallel the length of the dam, known as a hydraulic.

Dam pictured has claimed lives, though it looks harmless at low water levels.

The spinning action of the hydraulic increased the downstream current’s speed. Over time, debris and sediment accumulated below the dam to force the water into one main channel to create a venturi effect which further accelerates current speed.

Warning sign above the impounded water, and a note left on my truck warning of the danger dams present to paddlers.

A couple hundred yards below the dam, the flowing water surrenders its infused energy to rely on the gradient of the river bed to continue its seaward journey.

On a bright sunny day, after a warm June rain, I decided to accompany the river on its infinite downstream journey. I placed my black carbon fiber canoe a few feet from the sandy shore in about a foot of calm water before I climbed aboard. As the river bed naturally narrowed from the wide funnel shaped expanse created by the dam, accumulated sediment and debris blocked and shifted the main flow to the far shore.   

When I launch at this location, I always do an upstream ferry to experience the free energy the river supplies. A ferry will carry you across a river’s current with hardly any effort. No need to aim your boat far upstream of your intended landing while furiously fighting the current. I eased the boat into the current, bow upstream, to position it parallel to the flowing water, making it essentially invisible to the current. It is possible to sit motionless in fast water, as long as the boat remains perfectly aligned with the flow.  When performing an upstream ferry, point the bow in the direction you want to go, the angle depends on the speed of the current. It feels like magic as you entice the river’s energy to reveal itself and provide a counter intuitive assist to effortlessly cross a strong current.

Water level determines the downstream course. At low levels, winding channels in the river bed own the navigable water. This day the higher water left many options.

The sleek black canoe appeared as a dark shadow on the river bed, its passage as silent as its shadow, neither left a trail or a trace.

Where the river makes a bend, the water downstream, pools, as the flow crashes headlong into the river bank. Below each significant bend, a shoal will be formed with channels generally situated tight along either shore.

Immediately after one sharp bend, marked by a high red shale cliff, a navigable narrow passage runs very tight along the right steep shale bank, shrouded by overhanging branches. At lower water levels this channel is like running a gauntlet, though preferable to dragging the boat over the protruding shoal.

When the river passes under one old steel truss bridge, the river course is such that the main current bounces off the angled bank, causing an eddy of circulating water to form on both shores. An eddy shaves flowing water from the main course and the bow of a boat can suddenly be held still by the eddy and simultaneously the stern is swept downstream to overturn the canoe. Eddy turns are a basic maneuver a paddler should master, especially in high water where an eddy is not normally formed at lower levels. Get caught by surprise in an eddy in high water or off season will make you a believer in reading a river. Find a place where eddies form at lower water levels and learn the basics of fluid dynamics and effective paddle strokes and downstream braces.

On any given day the river can deliver a surprise that was not there the day before. Specifically, strainers, treetops which fall across the river blocking passage are especially dangerous. This is where a ferry can come in handy when you round a bend and see it blocked by a fallen tree. Tangled in branches with a water filled boat or current pressing you against an immovable object is a death sentence. Water weighs a pound a pint, and a boat full of water is beyond the strength of the most fit paddler to lift.

This is where a draw comes in handy. Kept the boat upright with a desperation draw.NEVER stop paddling, keep your paddle in the water!

Obstacles avoided; a stretch of open water begs the black canoe to be pushed to the limit of its design. The paddlers fitness and form are the rate limiting factors to speed the canoe’s shadow along the light tan river bottom.  At sixty strokes a minute, the paddle leaves a linear series of isolated, expanding ripples, lingering on the water’s surface, appearing like the tracks of a rabbit running in the snow. 

The black canoe is the cursor I used to help read the river’s mood and understand its personality. It was a good read with many twists and turns, the imagery impressive and maybe the best never ending story ever told.

Inaugural 5K “Run Off” a Great Success!

By Danielle Bongiovanni, LRWP 2025 Science Communication Intern

The Lower Raritan Watershed Partnership (LRWP) is overwhelmed with gratitude for everyone who helped raise over $3,500 at the “Run Off” 5k on Saturday, March 29 at Washington Memorial Park. Whether you were one of the 108 registered racers, bought tickets for the gift basket raffle, or simply came to learn the importance of keeping the Raritan Watershed clean, we were happy to have you there.

The “Run Off” would not have been possible without sponsorship from NJ American Water, Crunch Fitness of Green Book and the Borough of Dunellen. The Middlesex County Office of Emergency Management, Dunellen crossing guards, and volunteers from SEWA Central New Jersey and the LRWP ensured the event’s safety. 

Grant funding was provided by the Middlesex County Board of County Commissioners through a grant award from the Middlesex County Cultural and Arts Trust Fund. For information on events, go to MiddlesexCountyCulture.com.

“The Lower Raritan Watershed Partnership has been a grantee of ours through our program grants for arts, history and culture for years, doing either an arts project or a history project and intersecting that with the environmental issues they work on through their nonprofit. They’re one of a few environmental groups that receive arts, history and culture funding, so we love getting involved with them,” said Manda Gorsegner, the Division Head of Visual and Performing Arts at the Arts Institute of Middlesex County.

The Institute assisted with event planning by rallying visual and performing artists to bring attention to conservation through creativity. Gorsegner said, “Using arts, history, and culture to engage the public in environmental and social issues is really impactful and a unique way to talk about these stories and the importance of how we all intersect culturally and socially.”

Such conversations abounded as attendees visited tables set up by event partners. Spectrum for Living, a non-profit serving people with developmental disabilities, provided googly eyes, fake feathers and colorful paper squares for decorating wood cutouts of green herons. Crafters took home a reminder of who else depends on clean watersheds.

Independent artists Kate Eggleston and Lisa Bagwell repurposed litter into art supplies. Eggleston created plates for collagraph printmaking, while Bagwell used it as filling for a sculpture of a glass eel, a juvenile stage of the American eel.

Bagwell was in her element. “I do a lot of cleanups on my own, so making a sculpture out of collected trash is what I do,” she said. The completed sculpture will be toured across schools by the Hudson River Foundation’s NY-NJ Harbor & Estuary Program to raise awareness of waterway pollution.

Music poured from the pavilion, courtesy of the talented New Jersey Brass Band, part of the New Brunswick Jazz Project, and by jazz vocalist Audra Mariel.

One performer took his music to the streets instead. Dave Seamon, better known as the Trash Troubadour, performed his song “Miracle Mile” as he led attendees favoring a slower pace on a “Trickle” from the park to the Green Brook. There, LRWP Board Member Anton Getz and LRWP Community Outreach Coordinator Dr. John Meyer discussed the litter trap and the eel monitoring program.

The litter trap, nicknamed Bandit, was installed in the Green Brook as part of the Cornell-Dubilier Electronics Natural Resource Damage Assessment and Restoration (NRDAR) Restoration Plan. The Cornell-Dubilier NRDAR Plan is an example of how the nation’s strong Superfund Laws truly hold polluters accountable for environmental damages in our communities. Cornell-Dubilier Superfund Site Trustees include the National Oceanic and Atmospheric Administration, the US Fish and Wildlife Service and the New Jersey Department of Environmental Protection. The location of the litter trap, almost exactly at the intersection of Union, Middlesex, and Somerset Counties, is a pertinent reminder of how polluted water flows without regard for man-made borders. When the Dunellen Department of Public Works empties Bandit, Dunellen is not the only community benefitting.

The beneficiaries are not limited to humans! Getz recalled discovering a three-foot-long American eel hiding inside a tire during a cleanup of the Green Brook. “Those chemicals are leaching into its water, leaching into its environment, so it needs to find a better hideaway,” he said.

Meyer assured attendees that the litter trap did not hinder migrating eels. Bandit’s buoyant arms catch floating trash, but fish can easily swim beneath.

Back at the park, Green Brook Middle School students presented posters created in collaboration with the LRWP and New Jersey Watershed Ambassador Brianna Casario. They shared facts about the American eel’s life cycle and discussed the importance of citizen science.

The event concluded with the winners of the gift basket raffle, whose prizes were generously donated by local businesses. Congratulations were also awarded to the fastest 5k runners.  Dunellen residents took first in the male and female divisions, with Matthew Clemente recording a chip time of 21:27 and Lisa Shultz recording 27:16.

At the core of the “Run Off” 5k was the theme of connection. Attendees from across New Jersey supported conservation through the arts, sciences, and athletics. It proved how, regardless of your preferred discipline or your location, there is an opportunity for you to fight for healthy watersheds, and the LRWP would love to help you find it.
