Welcome to the latest edition of our “A Day in the Life” blog series! Today, we’re diving into the world of lake management, biological sampling, and watershed restoration with Patrick Rose, an Environmental Scientist and Project Manager in Princeton Hydro’s Aquatics Division.

Since joining Princeton Hydro in 2019, Pat has played a key role in a range of aquatic projects, from water quality monitoring to fisheries management. His expertise spans in-lake and watershed management, including cyanobacteria monitoring, invasive species control, and statistical analysis of water quality and biological data. Pat has contributed to major initiatives such as developing Nine Element Watershed Implementation Plans for two of New Jersey’s largest lakes, crafting cyanotoxin mitigation strategies, and conducting lake phosphorus assessments to guide restoration efforts.

His journey into aquatics began with a transformative summer course at Lake Atitlán in Guatemala, which ignited his passion for watershed science. After earning both an undergraduate degree in Environmental Science and a graduate degree in Lake Management from SUNY Oneonta, he spent a year with AmeriCorps in Knoxville, Tennessee, working on water quality initiatives with high school students and government agencies. He later completed a co-op managing aquatic invasive plants in the Pacific Northwest before joining Princeton Hydro as an intern in 2016, transitioning to a full-time role in 2019.

Now, let’s step into Pat’s boots (or waders) and see what a typical day in the field looks like—starting with the essential preparations before heading out on the water.

Preparing Equipment and Safety Gear for a Day in the Field

Pat’s days are as varied as the ecosystems he studies. When fieldwork is on the schedule, his morning starts early—often before sunrise. The first step is checking the weather forecast to anticipate any conditions that could impact the day’s work.

Next, he heads to the Princeton Hydro field office, where the team’s trucks, boats, and specialized aquatics equipment—such as the Truxor DM, Marsh Master 2MX-KC-FH, and Airboat—are stored. Before hitting the road, Pat and his team conduct a thorough inventory, gathering all necessary tools and performing critical equipment checks and calibrations.

[gallery link="none" size="medium" columns="2" ids="17135,17131"]

“It’s important to ensure that all of the equipment is accounted for and in good working order before leaving for the project site because the site can be a few hours away,” Pat explains. “We calibrate our water quality meters every morning to ensure that all of our measurements are accurate.”

Even for routine monitoring projects at familiar sites, planning is essential. Some projects require full-day or multi-day sampling efforts, especially when testing large waterbodies at multiple locations. A well-structured plan helps keep the process efficient while allowing flexibility for unexpected challenges. As part of the Health and Safety Plan (HASP), the team also reviews emergency protocols, including identifying key points of contact and the nearest hospital in case of an emergency.

If the project involves a boat, the team double-checks all required safety gear, including life jackets, fire extinguishers, flares, air horns, and first aid kits. They also bring protective gloves, especially when working in areas where harmful algal blooms (HABs) are suspected. To prevent the spread of invasive species, they follow strict decontamination protocols, washing boats at the end of each field day.

With the gear packed, safety checks complete, and a solid plan in place, it’s time to hit the water and begin the day’s fieldwork.

On the Water: Conducting Water Quality Monitoring in the Field

Once Pat and the project team arrive at the site, they prepare the boat for launch and conduct a final safety check before heading out on the water.

While they may have specific sampling locations identified in advance, the team remains vigilant for any additional signs of water quality issues, such as HABs, invasive aquatic weeds, or other ecological disturbances. They also take note of positive indicators of a healthy ecosystem, including native fish species, beneficial aquatic plants, and diverse wildlife activity.

Decisions about field measurements at each location are guided by the client’s directives, an approved lake management plan, and any known or suspected water quality challenges the team is working to mitigate.

One of the primary tools Pat relies on is the multiprobe water quality meter, which allows him to efficiently measure key water quality parameters, including temperature, dissolved oxygen, pH, and specific conductivity. This instrument provides real-time data, enabling the team to assess conditions on-site and make informed decisions about sampling and management strategies.

Watch this video where Pat demonstrates how to use a multiprobe water quality meter: [embed]https://youtu.be/6J1oV1qdh4k[/embed]

In addition to using the multiprobe, the team collects water samples for laboratory analysis, testing for conductivity, turbidity, nutrient levels, and, in some cases, fecal coliform bacteria. Shoreline assessments are also a crucial part of monitoring efforts. Pat and his team walk the banks to document erosion, bank stability, and native plant growth, recording their observations through field notes and photo documentation.

With data collection complete, the next step is analyzing the results and translating the findings into actionable insights.

Exploring Lake Hopatcong: A Case Study in Trout Habitat Monitoring

One of the projects Pat is most involved with is the trout habitat monitoring study at Lake Hopatcong, New Jersey’s largest lake. The lake’s trout fishery is a major recreational attraction, drawing anglers from across the region and contributing to the local economy. However, an analysis of 30 years of water quality data revealed a concerning trend—rising surface water temperatures, which can negatively impact trout habitat and survival rates.

[gallery columns="2" link="none" ids="17136,17132"]

In response to these concerns, the Lake Hopatcong Commission (LHC) Trout Committee was formed in 2021. Working in collaboration with the Lake Hopatcong Foundation and the Knee-Deep Club, the committee launched a three-year trout tagging study to evaluate the lake’s ability to support a sustainable trout population. Princeton Hydro is responsible for all technical aspects of the study, including data collection, analysis, and reporting, with funding provided by the New Jersey Highlands Council.

To understand how habitat conditions fluctuate during peak summer stress periods, Pat and his team conducted weekly sampling in July and August at both deep-water stations and nearshore areas. “We take GPS measurements at every site around the shoreline where we measure temperature and dissolved oxygen,” Pat explains. “Then, we send the locations to our GIS team so they can create detailed habitat maps.”

The study focuses on two key elements:

1. Deep-Water Sampling:

Pat and his team collect in-situ water quality profiles at five deep-water stations across the lake.
Using a calibrated multiprobe water quality meter, they take readings at 1-meter intervals from the surface to the lake bed, refining the intervals near habitat boundaries to improve accuracy.
Core parameters include temperature and dissolved oxygen, with additional data on specific conductance and pH.
These measurements help define the upper habitat limit (controlled by temperature) and the lower limit (governed by dissolved oxygen levels).

2. Nearshore & Stream Sampling:

Pat’s team surveys potential trout refuge areas along the shoreline, where trout might seek cooler, oxygen-rich waters in late summer.
Over the course of the study, they have sampled 116 locations in 2022 and 110 locations in 2023, gathering in-situ temperature and dissolved oxygen data to identify possible refuge sites.
They also measure these parameters in major stream inlets, assessing sources of cooler water that could support trout habitat.

By collecting and analyzing this data, the study provides critical insights into how trout habitat is changing and what can be done to protect and enhance suitable conditions for this important fishery. Click here to read more about the Lake Hopatcong Trout Habitat and Tagging Study.

Building Partnerships for a Thriving Lake

Managing aquatic projects isn’t just about addressing challenges—it’s about bringing people together to protect and enhance vital ecosystems. Successful water quality restoration efforts thrive on collaboration, education, and community engagement.

“Lakes serve many purposes, and different groups value different aspects,” Pat explains. “Fishermen often want sufficient aquatic vegetation for a healthy fishery, while boaters and swimmers typically prefer little to no vegetation. The best way to ensure a balanced approach is to involve all stakeholders in the conversation.”

At Lake Hopatcong, Pat and his team work closely with the Lake Hopatcong Commission, Lake Hopatcong Foundation, local government entities, volunteers, and community members. Regular communication and engagement efforts ensure that project goals reflect the needs of the entire community. By fostering open dialogue, gathering feedback, and sharing scientific insights, they aim to inspire stewardship and long-term investment in the lake’s health.

Looking Ahead

As Pat continues to make meaningful contributions to Princeton Hydro’s mission, he remains dedicated to expanding his expertise and leadership in lake and watershed management. He thrives on the balance between technical fieldwork, client collaboration, and mentorship, and he’s always eager to take on new challenges in aquatic science.

For students interested in the field, Pat emphasizes the value of hands-on experience: “Take as many courses as you can in aquatics and related fields,” he advises. “Seek out internships, research opportunities, or assist graduate students and professors. Real-world experience is invaluable.”

With passionate professionals like Pat leading the way, the future of lake management and watershed restoration is in good hands.

Welcome to our latest installment of the “A Day in the Life” blog series. Today, we delve into the fascinating world of Geographic Information Systems (GIS) analysis through the eyes of Tara Srinivasan. Tara, an environmental staff scientist for the Restoration & Resilience team and a GIS analyst, combines her passion for environmental research with the power of geospatial data to support sustainable projects that enhance ecosystems and communities alike.

GIS is a powerful technology used to study, analyze and visualize geospatial data. In Tara’s role at Princeton Hydro, GIS serves as both a creative and analytical tool, enabling her to generate and explore detailed maps of environmental conditions at project sites, such as vegetation, soils, topography, and water bodies. This process aids in identifying restoration needs, addressing challenges, and developing innovative solutions.

Let’s embark on a journey through a typical day in Tara’s role and uncover how her expertise helps shape Princeton Hydro’s environmental restoration projects.

Diving Into Data

Tara usually starts her day in the office, preparing to analyze data for a particular project. Using GIS software like ArcGIS, she examines historical and current imagery of the site, overlays habitat features, and maps property boundaries. These analyses help Tara and the project team understand the site’s existing conditions, such as watershed boundaries and the presence of threatened or endangered species.

“GIS allows us to study locations remotely, uncover patterns and features that might not be obvious on the ground, and understand how a place interacts with its surrounding environment,” Tara explains. “By incorporating extensive environmental data from local, state, and national resources - collected by both public and private organizations - I can gain a comprehensive view of a project site before we even set foot in the field.”

From calculating the impacts of a proposed restoration project to mapping flood conditions under various climate scenarios, Tara’s work ensures that Princeton Hydro’s environmental solutions are informed by robust spatial data and cutting-edge technology.

One project Tara is especially proud of is Princeton Hydro’s contribution to the Trenton Vulnerability Assessment, part of the Resilient NJ initiative administered by the NJDEP Bureau of Climate Resilience Planning. “We modeled flooding and urban heat islands based on current data and future projections of climate change, and created a mapping tool that overlaid hazard areas with Trenton’s critical facilities, community assets, cultural and ecological resources, and vulnerable populations,” she shares. Tara had the opportunity to present this data to Trenton residents, who shared their questions and ideas for solutions that the City incorporated into its climate planning efforts. “It was a great way to engage with our local Trenton community, get in-person feedback on our maps, and see the potential that GIS and environmental data have in informing social conversations,” Tara adds.

Delineating a Watershed

Today, Tara is focused on defining the boundaries of a watershed surrounding a small lake. In this video, she walks us through her step-by-step process for watershed delineation:

Collaborating Across Teams

Collaboration is a key part of Tara’s role. On a typical day, she meets with Princeton Hydro’s regulatory team to discuss GIS findings that inform project permitting and compliance. These partnerships enhance her work, ensuring that data analyses align with project goals and regulatory standards.

Tara also communicates her findings to clients and stakeholders who may not have technical GIS backgrounds. She uses intuitive maps, symbols, and colors—like blue for water and green for forests—to help stakeholders understand complex concepts at a glance. “Maps are a powerful thing,” Tara says. “They can bring people up to speed quickly and convey information in a way that words alone cannot.”

When maps become more intricate, Tara incorporates supplementary visuals, such as tables and graphs, to provide additional clarity. Her ability to bridge technical expertise with accessible communication is crucial for guiding clients through project decisions.

Fieldwork and Fresh Air

Although much of her work is office-based, Tara occasionally heads out into the field to collect data or monitor project sites. Equipped with GPS tools and field notebooks, she assesses topography, vegetation, and other site-specific details that feed back into her GIS analyses.

“Fieldwork provides a fresh perspective,” Tara notes. “It’s a great opportunity to see how projects are implemented and to observe how the environment evolves over time.”

Whether delineating watersheds or monitoring post-construction conditions, these outings connect Tara’s technical work to the tangible landscapes she aims to restore.

Overcoming Challenges with Innovation and Care

Tara thrives on finding innovative solutions to challenges in her work, such as optimizing software processes and addressing gaps in available data. Her meticulous organization of databases, attention to detail, and commitment to accuracy ensure that her outputs are both reliable and impactful. When data is limited, Tara ensures transparency by clearly communicating any uncertainties, fostering trust and confidence in her analyses.

Tara also approaches her work with a strong ethical lens, carefully considering the implications of GIS analyses on communities and ecosystems. “When you look at a map of a stream, lake, wetland, or forest in an urban area, it’s important to notice the houses, schools, businesses, parks, and other features that surround them,” Tara explains. “Our projects impact both the environment and people. GIS helps us examine a large area and assess our impact so we can minimize any temporary or permanent effects, both legally and ethically.” She notes that GIS can even identify already disturbed areas for construction access, helping preserve healthier habitats.

Continued Inspiration

Tara’s love for maps dates back to her childhood, when she was captivated by the intricate, hand-drawn maps in fantasy novels. Her fascination grew through exploring Google Earth, imagining future travels, and observing how geography shapes civilizations. This passion now drives her professional journey, where she uses GIS to merge her analytical skills with creativity. “I’ve always been a visual learner, so I find something grounding about orienting yourself on a map,” Tara shares.

When she’s not working, Tara enjoys wildlife photography hikes, baking experiments, and writing music for her ukulele—a testament to her creativity both inside and outside the office.

For Tara, GIS is more than a tool; it’s a gateway to understanding and addressing environmental challenges. Her work at Princeton Hydro highlights the versatility of GIS in projects ranging from wetland restoration to climate change resilience. Reflecting on her role, Tara says, “What I love most about GIS is its ability to bring environmental stories to life, helping people connect with the places they care about in a meaningful way.”

The Audubon Christmas Bird Count (CBC) is the nation’s longest-running community science bird project, fueling critical conservation efforts for over 12 decades. Each year, from December 14 to January 5, birders and nature enthusiasts participate in this hemispheric program, contributing valuable data about bird populations.

The CBC began in 1900 as a new holiday tradition proposed by U.S. ornithologist Frank Chapman, replacing the "side hunt" — a practice of hunting birds with no limit — with a more constructive and conservation-minded activity: counting birds to support science and protection efforts. That year, 27 observers counted 18,500 birds in 25 locations across the U.S. and Canada. Since then, the CBC has grown to include over 2,800 count circles across the Western Hemisphere, involving thousands of volunteers who tally birds within a designated 7.5 to 15-mile radius.

This data forms one of only two large pools of information that ornithologists and conservation biologists rely on to track bird population trends. For example, a 2019 study revealed a loss of nearly three billion North American birds since 1970. The data also informs how birds respond to climate change, guiding conservation efforts in an ever-changing environment.

Princeton Hydro’s Role in the Christmas Bird Count

The Audubon Christmas Bird Count is more than a science initiative; it’s a cherished tradition that brings communities together in support of bird conservation. Members of the Princeton Hydro team have embraced this opportunity to contribute valuable data while fostering a deeper connection with local ecosystems and creating a meaningful impact for birds and their habitats.

Princeton Hydro Vice President Mark Gallagher, an avid birder who has observed approximately 800 bird species in his lifetime, has been involved in the CBC since 1978 bringing both expertise and enthusiasm to the effort. He leads the Southern Bucks County (PA) Bird Count group, organizing and participating in the annual count event as well as coordinating with sub-area managers to compile and submit CBC data to the National Audubon Society.

The Southern Bucks County circle covers the Neshaminy Creek and Upper Delaware River, Philadelphia, Pennsylvania site, which was one of the original 25 locations surveyed during the first Christmas Bird Count in 1900. This long-standing tradition adds a unique historical significance to the data collected in this region and provides fascinating insights into long-term trends in bird populations.

This year, a Princeton Hydro team also participated in the Trenton Marshes Annual Christmas Bird Count, covering areas around Duck Island and the Delaware River. The group of six, spotted 50 species, including Orange-crowned Warbler, Fox Sparrow, Black-capped Chickadee, Rusty Blackbird, and several Bald Eagles.

One highlight of the day was observing a flock of Ruby-crowned and Golden-crowned Kinglets dancing and singing in an evergreen patch near the Trenton Sewage Utility Plant. The group also had an unforgettable experience when they imitated the descending, quavering whistle of an Eastern Screech Owl and received an answering call from the trees above—a thrilling moment that underscored the magic of connecting with wildlife.

[gallery ids="16936,16940,16937"]

Join the Tradition: Make Every Bird Count

The CBC offers an opportunity for everyone, regardless of age or experience, to contribute to this vital community science initiative. Birders must arrange participation with a local compiler and can choose to count in the field or from the comfort of their home by watching feeders. To see which count circles are nearest to you, visit Audubon’s CBC map.

In a press release, Dr. Brooke Bateman, senior director of climate and community science for Audubon, said: “The Audubon Christmas Bird Count is a great tradition and opportunity for everyone to be a part of more than 12 decades of community science in the name of protecting birds. Your Christmas Bird Count observations help scientists discover trends about bird species that inform conservation.”

In addition to the Christmas Bird Count, the National Audubon Society, Cornell Lab of Ornithology and Birds Canada host the Great Backyard Bird Count, which takes place February 14 - 17. This count is an accessible way to contribute to bird conservation by observing birds from any location for as little as 15 minutes.

As 2024 comes to a close, we’re proud to reflect on a year filled with meaningful achievements and memorable milestones. From groundbreaking projects to personal accomplishments, these successes highlight the dedication and innovation of our team and the strength of our partnerships. None of this would have been possible without the unwavering support of our clients, collaborators, and staff.

Join us as we celebrate the top 10 successes that made this year extraordinary:

1. Restored Free-Flowing Rivers in the Delaware River Watershed

This year marked major milestones in the restoration of three Delaware River tributaries. The removal of the 129-year-old Paulina Lake Dam on the Paulins Kill River reconnected an additional 7.6 miles of river habitat, adding to the 10 miles restored following the removal of Columbia Lake Dam. This project, led by The Nature Conservancy and designed by Princeton Hydro, represents a significant step forward in revitalizing New Jersey’s third-largest tributary to the Delaware River. The removal of Dam #2 on Bushkill Creek completed a five-dam removal effort, making the lower Bushkill Creek free-flowing and reconnecting it to the Delaware River for the first time in over 200 years. This effort enhances water quality, supports the passage of migratory fish, and bolsters freshwater mussel populations, vital to the health of the watershed. In November, work began to remove the Cedar Grove Dam, the first of four dams slated for removal along the Pequest River over the next year. This collaborative effort, led by The Nature Conservancy with training support from Princeton Hydro, will open nearly 10 miles of mainstem river and reconnect 57 miles of tributaries. Collectively, these dam removals celebrate a shared commitment to restoring ecological balance, reconnecting critical habitats, and supporting the biodiversity of the Delaware River Basin.

2. Designed & Implemented Urban Ecological Uplift Initiatives

Through engineering and ecological enhancements, we are revitalizing landscapes across the region. In New Jersey, the 279-acre Miry Run Dam Site 21 in Mercer County Park is being transformed into a vibrant public park that balances nature and community. We also collaborated with the Trenton South Ward Neighborhood Association on a Community Garden and Park Visioning project, assisting them in securing a grant that led to the planting of 500 native plants, enhancing public spaces and creating critical habitat for monarch butterflies. In Pennsylvania, Warrington Township’s Lion’s Pride Park is being converted into a resilient wetland complex with accessible pathways, demonstrating how ecological uplift fosters healthier communities. And, construction is now complete on the Turkey Foot restoration project within the John Heinz National Wildlife Refuge at Tinicum in Philadelphia. The project revitalized 7.5 acres of critical wetland and upland habitats, preserving Pennsylvania’s last freshwater tidal marsh and supporting migratory and threatened and endangered species. In New York, we broke ground on the Spring Creek (North) Ecosystem Restoration Project in Brooklyn and Queens, which aims to restore 43 acres of degraded habitat within Jamaica Bay into a mosaic of low marsh, high marsh, scrub shrub wetland, and maritime upland within a 67-acre footprint. Meanwhile, the addition of the Marsh Master® 2MX-KC-FH to Princeton Hydro’s fleet elevated the ability to combat invasive species like Phragmites australis with minimal ecological disturbance.

3. Earned 7 Prestigious Awards

Princeton Hydro was recognized as one of New Jersey’s “Top Workplaces of 2024,” a prestigious honor that highlights our commitment to fostering an inspiring and supportive work environment. Two of our project achievements received acclaim: the Musconetcong Island Park project earned both the New Jersey Future Smart Growth Award and the American Planning Association of New Jersey’s 2024 Great Places in New Jersey - Great Public Space Award for transforming an abandoned site into a riparian park. The City of Lambertville’s stormwater management initiatives received the NJDEP “Our Water’s Worth It” Award for advancing flood resilience and water quality. Additionally, the restoration of the historic Roebling Wireworks, home to our Trenton headquarters, earned the New Jersey Historic Preservation Project Award, and our President, Geoffrey Goll, PE, was honored with the “Catalyst for Sustainable Change” Award from Hold High the Torch for advancing STEAM education and environmental stewardship.

Did you know that some of the animals we fear the most are actually among nature’s most invaluable helpers? Bats, spiders, and snakes are often misunderstood, leading to fear and, sadly, even harm to these essential species. These misunderstood creatures might send shivers down your spine, but without them, our ecosystems would be in serious trouble!

If you missed our recent Facebook Live AMA presentation, "Fright or Fiction: Debunking the Myths about Bats, Spiders & Snakes," don’t worry — the recording is now available for on-demand viewing! This fascinating session featuring Michael McGraw, CSE, QAWB, ACE, Senior Project Manager and Wildlife Biologist at Princeton Hydro sheds light on the common myths surrounding these creatures, the roots of our fears, and the incredible ecological benefits they provide. Plus, he offers insights on how we can help protect them instead of fearing them.

By learning more about these creatures, we can contribute to a healthier, more balanced ecosystem — and who knows, we might even overcome a fear or two along the way!

Why Are Bats, Spiders, and Snakes Misunderstood?

Our fear of bats, spiders, and snakes often stems from cultural myths, sensationalized media portrayals, and fear of the unknown. Misunderstanding these species highlights how a lack of education can shape our perceptions. With knowledge and curiosity, we can move beyond fear, find beauty in their unique roles, and appreciate the essential contributions they make to our world. For instance:

Snakes: Many people fear snakes due to evolutionary instincts or exaggerated stories. While venomous snakes can pose risks in certain areas, the vast majority of snake species are harmless and would rather avoid humans. Snakes are crucial for controlling rodent populations and maintaining biodiversity.
Spiders: These eight-legged arachnids may look intimidating, but they’re natural pest controllers. Most spiders are harmless to humans and play a significant role in maintaining insect populations (preventing overpopulation) and ensuring a balanced ecosystem.
Bats: Often associated with spooky tales, bats are actually vital pollinators and pest controllers. A single bat can eat thousands of insects in one night; recent studies estimate that bats eat enough pests to save more than $1 billion per year in crop damage and pesticide costs in the United States corn industry alone. Bats are also essential for seed dispersal and pollination, contributing to the growth of plants like bananas, avocados, and agave, which is used to make tequila.

By addressing the roots of these fears, such as unfamiliar behaviors or misunderstood survival tactics, Princeton Hydro's webinar aims to replace myths with facts.

Myths Debunked

The webinar tackles several myths, including:

“All snake bites are deadly.” This is false. Only 15% of snake species worldwide are venomous, and even venomous snakes like king cobras prefer to avoid humans. In the Northeastern U.S., there are only two types of venomous snake species - Timber Rattlesnake (Crotalus horridus) and Eastern Copperhead (Agkistrodon contortrix) - both being extremely non-confrontational.
“Black widow spider bites are always fatal.” This is false. While black widow bites are venomous and can be painful, but they're rarely fatal to humans. Black widows are not aggressive and prefer to avoid confrontation. They usually only bite if they feel threatened, such as when their nest is disturbed. Their venom is primarily used to subdue prey, and fatal reactions in humans are very uncommon.
“Bats will fly into my hair.” This is false. Bats have no interest in your hair and use their excellent echolocation abilities to navigate, meaning they can easily avoid obstacles, and are primarily focused on catching insects, not nesting in human hair.

Bats, spiders, and snakes are ecological powerhouses! Snakes control rodent populations, reducing disease and property damage. Spiders eat disease-carrying insects, helping to maintain healthy ecosystems. Bats pollinate crops, disperse seeds, and consume agricultural pests, supporting food security and biodiversity.

How You Can Help

The webinar also discusses practical ways to coexist with and support these animals, including:

Educate Yourself and Others: Make a commitment to learning more about these creatures, share what you learn, and help to dispel myths and stigmas about these beautiful and beneficial creatures.
Create Safe Habitats: Minimize pesticide use, reduce light pollution around your home, protect natural habitats, and avoid interaction.
Reduce Fear-Based Actions: Learn how to safely relocate spiders or snakes instead of harming them.
Support Conservation: Do your part to support conservation organizations and initiatives to help ensure these creatures and their habitats are respected and protected.

We’re thrilled to announce that Princeton Hydro’s Senior Manager of Aquatics and Certified Lake Manager, Chris L. Mikolajczyk, has been appointed as President-Elect of the Colorado Lake and Reservoir Management Association’s (CLRMA) 2025 Board of Directors. This appointment highlights Chris’s dedication to lake management and his commitment to advancing aquatic resource conservation efforts.

CLRMA, which was founded in 1996, brings together citizens, scientists, and professionals with a shared passion for protecting Colorado’s lakes and reservoirs. The annual CLRMA board election took place on October 22, 2024 during the organization’s fall conference. This event, a cornerstone for water resource professionals and conservation advocates throughout Colorado, fosters connections and knowledge-sharing on aquatic ecosystem health, water quality, and the legal and financial aspects of lake management.

Chris will serve as President-Elect for a one-year term, after which he will become President. In this role, Chris will work closely with CLRMA members to plan and host educational events, including spring and fall conferences, and summer gatherings, such as lake appreciation days and family-friendly workshops. With his extensive experience in lake management, as well as a term as the President of the North American Lake Management Society (NALMS), Chris is well-prepared to contribute to CLRMA’s mission of protecting and enhancing Colorado’s lakes and reservoirs.

“It’s an honor to join the CLRMA board and have the opportunity to contribute to the sustainability of Colorado’s valuable water resources,” said Chris. “I look forward to collaborating with the CLRMA team to advance our shared mission of fostering resilient, healthy lakes and reservoirs.”

Chris joined Princeton Hydro in 1999 and has spent the past 25 years managing and restoring lakes and aquatic ecosystems. Over his career, he has led numerous lake management and water quality projects across the U.S. and has played an active role in professional organizations such as NALMS. Chris’s experience includes lake diagnostics, watershed management planning, stormwater quality modeling, and leading various aquatic restoration initiatives. He brings a wealth of knowledge to CLRMA and is excited to expand his involvement in Colorado’s lake conservation community.

Alongside Chris, the newly elected 2025 CLRMA Board members include:

President: Erin Stewart
Treasurer: Cindy Brady
Director: Alex Bentz
Director (1-year term): Caleb Owen
Director at Large: Steve Lundt

Additional CLRMA Board members who will continue their roles include Suresh Niraula (Past President), Meghan Chantler (Secretary), Claire Farmer (Director), and James Eklund (West Slope Director).

Together, the CLRMA board provides a forum for sharing expertise and solutions on issues facing Colorado’s lakes, from water quality and ecosystem resilience to watershed protection.

Princeton Hydro is proud to support Chris in his work with CLRMA as we continue our mission of delivering sustainable, science-based solutions for water resource management and lake restoration across the country. This mission has recently extended to Colorado, where we completed our first project—a bathymetric assessment of Fairplay Beach Reservoir in partnership with the Town of Fairplay. This project involved mapping the reservoir’s underwater landscape to support its conservation, adding critical data for future restoration and management efforts in this beautiful high-altitude ecosystem.

As we look ahead, Princeton Hydro is excited to bring our expertise to Colorado’s unique aquatic environments and partner with local communities and conservation organizations to protect the state’s natural resources. Stay tuned for more updates as we continue exploring new waters and contributing to sustainable resource management across the region.
