How healthy is your lake? July is Lakes Appreciation Month and we’re celebrating with a contest! To raise awareness about water quality, we're encouraging people who enjoy lakes to participate in a "Secchi Dip-In" for a chance to win a $100 gift card and a one-year membership to the North American Lake Management Association (NALMS).


What is the “Secchi Dip-In”?

The "Secchi Dip-In" is an annual citizen science event created by NALMS in 1994. It was developed in order to involve lake-goers and associations across North America in using a simple Secchi disk to monitor the transparency or turbidity of their local waterway.

This data collected is evaluated on a regional scale by NALMS and helps lake managers further understand the water quality of lakes in their region. Since 1994, more than 10,000 trained volunteers have generated 42,000 transparency records, giving a glimpse of lake water transparency at sites across North America and the world, according to NALMS.


How do I collect a Secchi sample?

Click below to watch a video demonstration from Senior Aquatics Manager Christopher L. Mikolajczyk, CLM. Chris explains how to properly use a Secchi disk, how to read the results, and how this simple method helps inform lake and pond management strategies.

If you'd prefer to read (vs. watching), we've got you covered with these step-by-step instructions:

1. What is a Secchi disk and what data is collected with it? The typical Secchi disk used in lakes is an 8-inch disk with alternating black and white quadrants. It’s lowered into the water until the observer can no longer see it. The depth of disappearance, called the Secchi depth, is a measure of the transparency of the water. The disk is named in honor of Father Pietro Angelo Secchi, astronomer and scientific advisor to the Pope, who tested this new instrument in the Mediterranean Sea on April 20, 1865.

2. Where can I get a Secchi disk? Secchi disks are a low-cost investment and a great tool to have for measuring water quality. You can purchase a Secchi disk on the internet for $20-$30. Alternatively, you can always ask a friend or your local lake manager to borrow one. Some people even make their own!

3. How do I take a measurement? How many times do I do it? A measurement is taken by lowering the disk on the sunny side of the boat. To eliminate sun glare, an underwater viewer (viewscope) can also be used if so desired. Allow sufficient time (preferably 2 minutes) when looking at the disk near its vanishing point for the eyes to adapt completely to the prevailing luminance level. Record the depth at which the disk disappears. Slowly raise the disk and record the depth of reappearance. The “Secchi depth” is the average depth of disappearance and reappearance. For further accuracy, several people can each record several Secchi depths. Then, all of the depths can be averaged into one single reading. Please note: the water depth should be at least 50% greater than the Secchi depth so that the disk is viewed against the water background, not bottom-reflected light.

4. What's the best time of day to collect a sample? The best time of day to collect a sample is when the sun is at its highest point in the sky, generally around midday. Most volunteers generally collect data between the hours of 10:00 AM and 2:00 PM.

5. What do the results mean? The Secchi disk measures transparency, which serves as an indicator of changing water quality. Transparency decreases as the amount of particles in the water— such as algae and sediment—increases.

Princeton Hydro, LLC celebrates two decades of business and unveils its new look!

Today, Princeton Hydro, LLC is proud to celebrate 20 years since its inception. Princeton Hydro has grown from a small four-person idea operating out of a living room to a 53-person qualified small business with five office locations in the Northeast region. Last year, the firm generated $7.5 million in revenue, as it continues to grow its market share and breadth of ecological and engineering services. “We are committed to changing the world we live in for the better.  In everything we do, we strive to improve our ecosystem and our quality of life. This firm was originally built upon the ideal of creating a workplace of innovation and passion in the areas of science and engineering,” said Geoffrey Goll, Princeton Hydro’s current President and co-founder. “And, we did not do it alone; the people that were brought aboard helped grow us to what we are today, and will continue to increase our reputation of honesty, integrity, and creativity.” Two decades ago, Mark Gallagher; Geoffrey Goll, P.E.;  Dr. Stephen Souza; and Dr. Fred Lubnow, along with several staff decided it was time to leave the corporate culture to start a new company focused on the management and restoration of water resources. All four had been employed by a small business named Coastal Environmental Services when it was bought out by the large engineering firm Post Buckley Schuh and Jernigan (PBSJ) in 1996.  None of the “fab four” really fit the “big company” mold, and so the highly regarded wetland scientist, top-notch professional engineer, and well-respected aquatic ecologists formed Princeton Hydro; a company with a mission true to their environmental roots and consistent with their moral compass. “It’s hard to believe that it has been 20 years since our humble beginning in a small office, a former dance studio lined with mirrors, above a gym in Lambertville. I am proud, yet, still somewhat amazed at how the firm evolved into a well-respected firm of over 50 employees with offices in four states,” stated Mark Gallagher, Vice President and co-founder. “All this from a few important decisions made over breakfast at a Denny’s on Route 1 in 1998 that established a vision for this company. Since that breakfast, we have had the opportunity to implement this vision and to steward the development of Princeton Hydro.”   After moving from their home office to Lambertville, New Jersey in the same building as the original River Horse Brewing Company location, the company began to grow. At times they struggled to make ends meet, but by supporting each other and celebrating their accomplishments, the team pushed forward. Eventually, they grew so much that they moved down the road to their own office space in Ringoes, and then branched off with offices in southern New Jersey, Eastern Pennsylvania, Connecticut, and Maryland. The firm and its people have won dozens of awards since its founding; the most recent honor includes the 2018 "Land Ethics Award of Merit” presented by Bowman's Hill Wildflower Preserve to Princeton Hydro and GreenVest, LLC for their restoration work at the Mullica River Wetland Mitigation Site. “Over the years we remained true to our goal of doing right by the environment. Princeton Hydro has grown from a humble start-up to a well-recognized and respected leader in the management and restoration of our water, wetlands and natural resources,” said former President and co-founder Dr. Stephen Souza. “Thank you to all that have supported us and have helped us grow. Here’s to another successful 20 years!” Importantly, it is at this point in the company’s history, the firm’s future is no longer solely dependent on its four founders as its future now relies heavily on the firm’s leadership team and staff to continue the firm’s growth into its next 20 years.  The Princeton Hydro team has the skill sets necessary to conduct highly comprehensive assessments; develop and design appropriate, sustainable solutions; and successfully bring those solutions to fruition. All of our ecological investigations are backed by detailed engineering analyses, and all of our engineering solutions fully account for the ecological and environmental attributes and features of the project site. “I can't believe 20 years have passed since the establishment of our firm. This is an absolute testament to Princeton Hydro's core principle of bringing together the best, most innovative people to preserve and restore a variety of ecosystems throughout the Mid-Atlantic region,” said Dr. Fred Lubnow, Director of Aquatic Programs and co-founder. “It has been a pleasure to work with Steve, Mark, Geoff and all of the staff at Princeton Hydro over the last 20 years. I’m looking forward to many more!” As part of Princeton Hydro’s 20th anniversary celebration, the firm unveiled a refreshed brand which includes a new logo, 20th anniversary logo, colors, and style. As we transition into this new look, we’ll be updating our online presence and external communications over the next few months.  This new style matches the evolution of our company since our original “pH” concept was designed in 1998.

Here's a Recap of Projects Recently Completed by the Princeton Hydro Aquatic & Engineering Departments
Members of our New England Regional Office team conducted a detailed survey at a culvert prioritized for replacement in the Town of Stony Point, New York. This structure was one of several identified as important to both habitat and flood risk during the development of Stony Point's Road-Stream Crossing Management Plan. The Princeton Hydro team will use the collected data to develop a conceptual design and implementation strategy for a replacement structure using the Stream Simulation design method developed by the U.S. Forest Service. Special thanks to Paul Woodworth, Fluvial Geomorphologist, and Sophie Breitbart, Staff Scientist, for their excellent work on this project!

The Truxor was put to work dredging a pond in Union Gap, New Jersey. The Truxor is an extremely versatile amphibious machine that can perform a variety of functions, including weed cutting and harvesting, mat algae and debris removal, silt pumping, channel excavation, oil spill clean-up, and much more!

We recently designed and installed a solar-powered aeration system in Hillsborough, New Jersey. Solar pond and lake aeration systems are cost-effective, eco-friendly, sustainable, and they eliminate the need to run direct-wired electrical lines to remote locations. Princeton Hydro designs, installs and maintains various aeration and sub-surface destratification systems for public drinking water purveyors, municipal and county parks, private and public golf courses, and large lake communities throughout the East Coast.

Here’s a look at a project in Elizabeth, New Jersey to clear the area of phragmites. Phragmites is an invasive weed that forms dense thickets of vegetation unsuitable for native fauna. It also outcompetes native vegetation and lowers local plant diversity. Previously, the entire site was filled with phragmites. Late last year, we utilized the Marsh Master to remove the invasive weed. Now that its almost Spring, we’re back at the site using the Marsh Master to mill and cultivate the ground in preparation for re-planting native plant species. A big shout out to our Aquatic Specialist John Eberly for his great work on this project!

In this photo, Princeton Hydro team member gathers data on the Hughesville Dam removal, using GPS to check the elevation of the constructed riffle on the beautiful Musconetcong River. In this photo, our intern and engineering student currently studying at Stevens Institute of Technology, Veronica Moditz, is gathering data on the Hughesville Dam removal. She’s using GPS to check the elevation of the constructed riffle on the beautiful Musconetcong River.

Members of the Princeton Hydro team worked in South New Jersey doing annual maintenance on nine stormwater infiltration basins that were also designed and constructed by Princeton Hydro. The maintenance work involves clearing vegetation from the basins to ensure the organic matter does not impede infiltration of the water as per the basins’ design. This project also involves the management of invasive plant species within the basins. Stormwater infiltration basins provide numerous benefits including preventing flooding and downstream erosion, improving water quality in adjacent waterbodies, reducing the volume of stormwater runoff, and increasing ground water recharge.

We recently completed a project in New Jersey for which we used our Truxor machine to dredge a stormwater retention basin. The basin had accumulated large amounts of sediment which were impeding the flow of water into the basin. We equipped the Truxor with its standard bucket attachment and a hydraulic dredge pump. The dredging operation was a success and now the basin is clear and functioning properly.
