How’s the Fishing? Tips for Managing Your Lake’s Fishery

The fishery of a lake is an intrinsic, incredibly dynamic element of a lake system, and managing a lake’s fishery can be a very complex endeavor. There is actually a lot more to it than simply stocking game fish. Although there is no “one way” in fisheries management, there are key guidelines that can be followed to maximize the recreational potential of your lake’s fishery and increase the success of your fishery management and stocking efforts. Over the past two decades, Princeton Hydro has been working with lake, pond, and reservoir managers to help them to align water quality, fishery, and ecological goals.

Princeton Hydro’s Founder, Dr. Steve Souza, recently gave a presentation on fisheries management at the Spring Meeting of the New Jersey Coalition of Lake Associations (NJCOLA). We’ve compiled a few essential elements from his presentation and have made the complete presentation available for free download.

Let’s dive in!

Benefits of a Healthy Fishery

Recreational fishing is an outdoor activity that can be enjoyed by people of all ages. When children are introduced to fishing, it helps cultivate a connection to the environment, thereby promoting outdoor activity and environmental stewardship among today’s youth.

Anglers have always served as important advocates for the conservation of natural resources. The sale of fishing licenses financially supports wildlife habitat conservation and enhancement as well as the protection and improvement of water quality. This increases the ecological services and functions of lakes and adds to their societal and recreational benefits.

A healthy fishery can have significant positive impacts on water quality. In a balanced, healthy fishery the ratio of forage and game fish affects the entire food web, helping to maintain the proper balance of zooplankton and phytoplankton. The “top down” ecological control associated with a balanced fishery minimizes algae blooms, sustains good water clarity and stable water quality. However, when the fishery is out of balance, the water quality and overall ecological health of the lake often suffers.

Before You Stock, Know Your Lake and Start with a Baseline

Before you do any fish stocking, it’s best to conduct a fishery survey. A fishery survey provides the vital data needed to design a stocking and management plan.

A balanced lake fishery is dependent on good water quality, ample habitat, and the correct ratio of predator and prey fish species. A properly designed and implemented fishery survey generates the data needed to quantify the overall composition of the existing fish community (predator vs. prey), the make-up of the forage (food) base, and the density and robustness of the lake’s top piscivores (prized game fish).

The resulting data helps identify if your fishery is balanced, which fish to stock, and how many of each species to introduce. It will also provide the benchmarks needed to solidify your management goals and, later on, help determine if the goals are being met. To stay on track, we recommend that a comprehensive fishery survey be conducted once every three years. Be sure to use the correct types and combination of “active” and “passive” sampling gear and thoroughly sample both the open water and nearshore areas of the lake.

The survey should include the collection and analysis of water quality data, and the mapping of available habitat. Water column water quality “profiles” provide vital information pertaining to the lake’s thermal and dissolved oxygen properties; key factors for a healthy, vibrant fishery. Here are some basic water quality guidelines:

  • Dissolved oxygen: ≥ 4 mg/L with 6-7 mg/L being ideal
  • For warm water fishery: Uniform temperatures at all depth (minimal or no thermal stratification)
  • For cold water fishery: Deep water temperature of 15 C, and dissolved oxygen ≥ 5 mg/L
  • pH: 6 to 8
  • Clarity: ≥ 3 feet (1 meter) Secchi disc transparency
  • Total Phosphorus: < 0.05 mg/L
  • Chlorophyll a: < 20 µg/L

Water quality sampling should also include an assessment of the lake’s zooplankton and phytoplankton communities, the base of your lake’s food web.

Floating Wetland Island

During the survey, take the time to quantify and map the distribution of existing forage, spawning, and refuge habitat. Lack of adequate habitat can significantly impede the fishery’s sustainability. This begins with the bathymetric mapping of the lake, which is basically an underwater survey of the bottom of the lake. This mapping shows where and how much shallow water versus open water habitat exists.  It can also help identify the location and distribution of important habitat types, such as shoals, rock piles, sandy open areas and natural structures (tree falls and snags). The data also helps determine where to create and introduce habitat, which can be in the form of brush piles, floating wetland islands, and other types of features that increase the spawning, recruitment, and foraging success of the fishery.

Stocking Your Lake

Once the fishery survey is completed, habitat is mapped and water quality analyzed, stocking can begin. In order to determine the specific stocking levels and rates that are right for your waterbody, here are some factors to consider:

  • Ensure your stocking efforts create or augment the correct ratio of predator (game) and prey (forage) fish.

  • Stock cautiously, focusing on a simple composition of predator and prey species. For most warm water lakes, largemouth bass should serve as the top predator and fathead minnow should be the primary prey.

  • Avoid problem fish, such as golden shiner, alewife and brown/black bullhead. Although these fish are often promoted as suitable forage species, they can be easily get overstocked and cause major disruptions of the fishery and to the degradation of water quality.

Go here for a more in-depth look at how to properly stock your fishery.

In Summary

A healthy sustainable fishery isn’t only a function of the types and amounts of fish stocked in a lake; it is directly a function of water quality, the availability and quality of spawning, foraging and refuge habitat, the ratio of forage to predator fish, and the overall composition and balance of the food web.

Begin with a fishery survey; the resulting data enables a correctly planned and implemented stocking program. Conduct routine surveys to assess the status of the fishery and the success of the program. Also, annual water quality testing provides the information needed to make wise pro-active fishery management decisions. It will also provide insights into the lake’s environmental conditions to ensure they are supportive of a healthy, productive and sustainable recreational fishery.

CONTEST ALERT: Celebrate #LakesAppreciation Month and Win $100

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 Amazon 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?
  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 Amazon or other online marketplaces 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.

“Floating Classroom” Launches into Lake Hopatcong

The Lake Hopatcong Foundation (LHF) recently launched its newest initiative – a floating classroom. The custom-built 40-foot education vessel, named ‘Study Hull’, gives students an interactive, hands-on education experience to explore Lake Hopatcong, learn about freshwater ecology, and learn how to protect the watershed.

During its maiden voyage field trip, which was held on May 21, fourth-graders from Nixon Elementary and Kennedy Elementary schools utilized the boat’s laboratory instruments to study water hydrology, temperatures, plankton, and dissolved oxygen levels. They performed a series of tests and experiments designed to help them learn about the general health of the lake. They used Secchi Disks to determine the depth to which light is able to penetrate the water’s surface. They also learned about runoff and nonpoint source pollutants, how to protect the lake’s water quality, and how to be good stewards of the water.

Princeton Hydro helped the LHF design a teaching curriculum on water quality.  Dr. Jack Szczepanski, Senior Aquatics Scientist, and Christopher L. Mikolajczyk, CLM, Senior Project Scientist, trained the staff and volunteers on the curriculum and demonstrated various water quality monitoring techniques that can be conducted with the students.

“We’re really proud to be a part of this exciting initiative,” said Mikolajczyk. “It’s really important to get kids interested in science at an early age and teach them about their surrounding environment – where their drinking water comes from, how it gets polluted, the impacts pollution has on the lake’s ecosystem, and what steps can be made to protect the lake’s water quality. We’re hoping the floating classroom field trip program will make a lasting, valuable impression with these kids.”

In the first year of operation it is expected that the Study Hull will host 1,000 fourth grade students. The long-term goal is to develop lesson plans for students in every grade from kindergarten through high school. Starting in July, the LHF is also offering the public tours of the floating classroom on Mondays at Hopatcong State Park.

The purchase of the floating classroom was made possible by financial support from USATODAY Network’s “A Community Thrives” program, which awarded the LHF with a $50,000 grant. The program recognizes three categories: arts and culture, education, and wellness. In each category, the first place winner received a $100,000 grant and the second and third place winners received $50,000 grants. The James P. Verhalen Family Foundation and the Szigethy Family also provided significant donations to help bring the floating classroom to life.

 

The LHF and Princeton Hydro are longtime partners. Starting back in 1983, Princeton Hydro’s Dr. Stephen Souza conducted the USEPA funded Diagnostic Feasibility study of the lake and then authored the Lake Hopatcong Restoration Plan. That document continues to be the backbone of why and how to restore the lake, manage the watershed, reduce pollutant loading, and address invasive aquatic plants and nuisance algae blooms.

Lake Hopatcong has one of the longest, continuous, long-term ecological databases in New Jersey; almost 30 years of consistently collected water quality data. The data is crucial in assessing the overall ecological health of the lake and proactively guiding its management, identifying and addressing emerging threats, documenting project success (a mandatory element of funding initiatives) and confirming compliance with New Jersey State Water Quality standards.

Princeton Hydro’s most recent work for Lake Hopatcong includes the implementation of green infrastructure stormwater management measures, installation of floating wetland islands to improve water quality, and invasive aquatic plant species management programs, community educational training, and surveys.

The Western New York Harmful Algal Blooms (HABs) Summit, the last of four Statewide HABs summits, was held last month in Rochester, NY. The summits kicked off Governor Cuomo’s $65 million initiative to protect the NY State’s lakes, ponds and reservoirs, and those that rely on these waterbodies for recreation and drinking water, from the ecological and health impacts associated with HABs.

“Protecting New York’s natural resources is key to ensuring residents have access to safe water, and through this collaborative summit, we are addressing the growing threat of harmful algal blooms,” said Governor Cuomo in a recent press release.

Each regional summit involved a day-long session of expert presentations and panel discussions on a variety of HAB related topics, and culminated in an evening session, which was open to the public and provided community members an opportunity to learn more about the Governor’s initiative and pose questions to NYSDEC about HABs and the management of HABs. The evening sessions were available to view via a live online stream as well.

For each summit, the Governor invited regional experts to participate along with NYSDEC and Department of Health experts. The experts were brought together to initiate the development of tailored HAB action plans. Although the focus was placed on the management of Governor Cuomo’s 12 priority waterbodies, the goal was to identify HAB management plans applicable for all of the State’s waterbodies, large or small. The discussions that evolved through the four summits set the stage to inform decisions related to preventing and properly responding to HABs across the state.

Participating by the invitation of Governor Cuomo and the NYSDEC in last month’s Western New York Summit were:

  • Dr. Steve Souza, Princeton Hydro
  • Art DeGaetano, Cornell University
  • Christopher Gobler, SUNY Stony Brook
  • Dave Matthews, Upstate Freshwater Institute
  • Greg Boyer, SUNY ESF
  • Nelson Hairston, Cornell University
  • Sally Flis, The Fertilizer Institute
  • Tim Davis, Bowling Greene State University, Ohio

During the Western New York Summit, Dr. Souza, Princeton Hydro co-founder, provided insight on the causes of HABs and, in particular, discussed the management techniques that have been successfully implemented by Princeton Hydro to combat the onset and mitigate the impacts of HABs.

About Governor Cuomo’s Harmful Algal Blooms program:
Governor Cuomo’s program builds on New York’s $2.5 billion Clean Water Infrastructure Act investments in clean water infrastructure and water quality protection. The Harmful Algal Blooms initiative is supported with funds from both the Clean Water Infrastructure Act and the $300 million Environmental Protection Fund. Through the Governor’s leadership, New York has developed the most comprehensive HABs outreach and monitoring programs in the country, led by DEC sampling of ambient waters across the state and DOH sampling at regulated beaches and public water systems.

2018 Watershed Congress Synopsis

The Delaware Riverkeeper Network hosted its annual Watershed Congress event, which is focused on bringing environmental enthusiasts together in an effort to advance the best available information and techniques for protecting and restoring watersheds. The one-day conference combines science, policy, and practical applications into one program that consists of an engaging keynote discussion, exhibits, poster sessions and 21 concurrent presentations covering a broad range of watershed topics.

Princeton Hydro gave two presentations during the event:

Ecology/Management of Cyanotoxin Producing Blue-Green Algae in the Schuylkill River 

Dr. Fred Lubnow, Director of Aquatic Programs, presented on the basic ecology of nuisance blue-green algae and how to monitor, manage and prevent cyanotoxins particularly in potable water supplies.

As identified in the Schuylkill River Watershed Source Water Protection Plan, approximately 1.5 million people depend on the Schuylkill River watershed as a source of potable water. Elevated nutrient (nitrogen and phosphorus) loading can stimulate the growth of nuisance algal blooms in the river, and higher phosphorus concentrations can cause blue-green algae blooms (also known as cyanobacteria). Cyanobacteria produce cyanotoxins, which can cause serious health implications for humans, pets and livestock. Drinking water contaminated by very high cyanotoxin concentrations can actually be lethal.

Fred’s presentation covered the ecology and management of blue-green algae in a riverine ecosystem in order to prevent the potential impacts of cyanotoxins on potable supplies of water. He provided management actions within the context of USEPA’s recommended drinking water health advisories for select cyanotoxins. Participants also received general recommendations on what they can do to minimize their contribution to potential cyanotoxin-producing blue-green algal blooms in the Schuylkill River.

If it’s a BMP, Will it Protect Water Quality?

Michele Adams of Meliora Design and Princeton Hydro’s Senior Project Manager, Dr. Clay Emerson, PE, CFM, taught an interactive presentation and group discussion on stormwater Best Management Practices (BMPs) and issues.

The presentation covered a variety of stormwater management topics and techniques, including the Pennsylvania Department of Environmental Protection’s Interim Final BMP 6.4.11 Draft Slow Release Concept, which allows for slow release when infiltration is not feasible. They also discussed evolving standards for bioretention/rain garden soils, the lack of requirements for construction oversight, inspection of stormwater BMPs, and the challenges of long-term stormwater BMP maintenance and performance.

Stormwater management has evolved from its peak-flow based infancy into a more comprehensive approach that addresses volume and water quality in addition to peak flow rate. The number of built examples of different types of stormwater management and green infrastructure has greatly increased in Pennsylvania. However, experience suggests that under the current state of practice, many stormwater management designs are not able to meet the goal of water quality protection.

The main goal of the session was to provide participants with the information they need to understand and ask the right questions in order to protect their watersheds as development occurs.

About the Watershed Congress

The Watershed Congress advances the best available information and techniques for protecting and restoring watersheds. The focus on networking across disciplines means that the Congress melds science, policy and practical applications into one program. Every year, a growing and changing group of individuals attends to gain new knowledge, acquire tools, and practice techniques that will allow them to take active roles in the stewardship of their natural resources.

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.
