That connection does not stop on land. It continues below the surface of our lakes, rivers, and wetlands. Aquatic plants play a critical role in maintaining water quality and supporting life. They produce oxygen, stabilize sediments, absorb nutrients, and provide essential habitat for fish, waterfowl, and invertebrates. In many ways, they are the foundation of a healthy aquatic ecosystem. Without them, water bodies can quickly lose balance.

However, like any natural system, balance is key. Too little vegetation can lead to erosion, poor habitat, and declining water quality. Too much growth can restrict water flow, limit recreation, and contribute to issues like low oxygen levels and algae blooms as plants die and decompose. Excess nutrients from runoff, changing weather patterns, and other environmental pressures can all shift that balance in the wrong direction.

Managing aquatic plants is not about removing them entirely. It is about maintaining a healthy, functional system. Mechanical harvesting and targeted removal can control excessive growth while preserving beneficial vegetation. Aquarius Systems has worked with lake managers, municipalities, and contractors to remove overgrowth in a way that improves water flow, supports recreation, and helps maintain overall water quality.

Healthy aquatic plant communities lead to clearer water, stronger ecosystems, and better recreational opportunities. Whether you are managing a lake, river, or pond, understanding the role of aquatic plants is an important step toward long term water health.

Glyphosate is one of the most heavily used herbicides in the world. Regulatory decisions surrounding its approval have relied on research evaluating toxicity, exposure limits, and environmental impact. When a study that helped shape public confidence is pulled back, it naturally raises broader questions. Science is meant to evolve. That’s not a flaw — it’s the process. But it does highlight the importance of independent review, long-term data, and open disclosure of funding and methodology.

The same framework applies to aquatic herbicides used in lakes, ponds, and reservoirs. These products are also deemed safe when applied according to label directions, based on studies measuring water concentration levels, species sensitivity, and breakdown rates. Yet water systems are complex. Variables such as temperature, oxygen levels, sediment composition, and nutrient loading all influence outcomes in real-world conditions. Ongoing evaluation matters.

For communities managing aquatic vegetation, the discussion often comes down to balancing effectiveness, cost, and environmental impact. Mechanical harvesting, for example, physically removes vegetation from the water body — along with the nutrients contained in that plant material. Left in place, excessive vegetation eventually dies and decomposes, releasing nutrients that can contribute to algae blooms and reduced oxygen levels. Different management tools bring different trade-offs.

What the glyphosate retraction ultimately reinforces is this: sound environmental decisions depend on sound science. That science must be transparent, repeatable, and open to scrutiny. Whether addressing agricultural weeds or aquatic vegetation, long-term ecosystem health depends on continually testing assumptions and being willing to re-examine conclusions when new information emerges.

Eurasian water milfoil grows aggressively, uprooting native vegetation, disrupting aquatic habitats, and interfering with recreation. By 2013, the Commission was spending up to $250,000 per year on herbicide treatments to control approximately 300 acres of milfoil. Grants helped fund these efforts, but by the mid-2010s, funding had dwindled to around $50,000 annually.

After a decade of chemical treatment, the Commission made a bold decision to stop using herbicides altogether. The results? Within a few years, the milfoil population began rebounding. According to the aquatic ecologist who has monitored these lakes for 18 years, the plant is “too big, it’s too much” for manual removal alone, which costs roughly $2,500 per day.

The lesson is clear: eradication with herbicides is expensive, temporary, and environmentally damaging. Even if chemicals were used without regard for ecological impacts, controlling the entire population long-term is not practical.

Instead, a management-focused approach should to taken to target plants that interfere with navigation and recreation rather than attempting total eradication. Mechanical harvesting offers a solution; it doesn’t attempt to eliminate every plant but efficiently manages growth, maintains recreational access, and avoids repeated herbicide costs.

After more than a decade of observation, the evidence is in: spending hundreds of thousands of dollars chasing eradication with chemicals is far less effective than strategic, mechanical management. It’s time for a shift in mindset: toleration and control, rather than endless eradication efforts, may be the only sustainable way forward for our lakes.

What’s Behind the Wake Boat Trend? Wake boats are equipped with ballast tanks that can take on thousands of pounds of water, allowing riders to surf waves nearly 3 ft high at speeds around 11 mph. Born from a booming $13,000‑boat segment that surged 20% in 2020, they are symbols of modern lake culture—freedom, thrills, and community—even as they stir controversy.

Why It Matters:

• Ecosystem Health: Waves can reach the lake bottom in shallower waters, uprooting plants and stirring sediment that releases phosphorus—fuel for algae blooms—and disrupts fish habitat.
• Shoreline Erosion & Property Impacts: Sudden wake surges hit docks and shorelines hard—rattling boats, damaging rip‑rap, and unsettling paddlers.
• Recreational Conflict: Lake users like kayakers, swimmers, anglers, and wake surfers often collide—literally and culturally—prompting complaints, legal suits, heated town meetings, and damaged community spirit.

Policy Landscape Across States: Out East and North, states are acting fast. Maine restricts wakesurfing to ≥15 ft depth and ≥300 ft from shore; Vermont demands ≥20 ft depth and ≥500 ft buffer plus “home-lake” rules; New Hampshire is debating either 200 or 300 ft setbacks; Michigan aligned on 200 ft but deeper restrictions were proposed then stalled; Minnesota and Michigan default to 100 ft buffer with education programs.

Wisconsin, with over 15,000 lakes, remains at the crossroads. Patchwork local bans fill gaps while proposed bills to limit wake boats by lake size, depth, or setbacks (200–700 ft, 30 ft depth) fail to gain state traction. A coalition led by Wisconsin’s Green Fire and Last Wilderness Alliance is calling for statewide minimums: 700 ft buffer, 30 ft depth, no wakes in lakes under 1,500 acres—while preserving stronger local rules.

The Science & Emotion Mix: Research paints a complex picture: some studies show natural decay of waves beyond 200 ft, others show ecological damage at 500 ft. Industry-funded scientists argue wake boats are no different than other boats at similar distances; critics point to real-world impacts—erosion, algae, upset kayaks—as compelling evidence.

The Path Forward:

• Balanced Regulation or Education? Do we need rigid statewide rules—or layered solutions combining minimum setbacks, mandatory depth zones, and local flexibility?
• Enforcement and Buy-In: Establishing signage, launching community monitoring, and supporting DNR enforcement are key to fair implementation.
• Science That Matters: Ongoing independent studies, not industry-funded ones only, are vital to build trust and guide policy that protects both ecosystems and enjoyment.

Wisconsin isn’t alone in challenging this modern watercraft dilemma. As states from Maine to Tennessee fill the regulatory wave, Wisconsin’s choices now could set a model for communities everywhere: curbing environmental damage without sinking the joy of recreation. The question facing taxpayers, lake associations, and lawmakers isn’t whether wake boats are fun—they are. It’s whether their wake washes away what we value most: lakes as shared, healthy, enduring places.

The Apple River Protection and Rehabilitation District (ARPRD) reported removing roughly 2.73 million pounds of aquatic vegetation from the Apple River Flowage as of June of this year. This follows back-to-back years where totals reached around 3.8 million pounds, highlighting a consistent and highly productive management program.

Keeping the Flowage Open and Healthy

The 640-acre Apple River Flowage sits within a watershed that covers more than 111,000 acres. As with many Wisconsin waterways, invasive and fast-growing native plants—like coontail and curly-leaf pondweed—can quickly limit boating access, trap nutrients, and reduce dissolved oxygen levels if left unmanaged.

Through consistent mechanical harvesting, the ARPRD helps maintain navigation channels, improve water flow, and reduce the buildup of decaying plant matter that can lead to poor water quality. Unlike chemical treatments, mechanical removal takes the vegetation out of the water entirely, helping reduce nutrient recycling and long-term regrowth.

A Sustainable Approach to Aquatic Management

Mechanical harvesting is one of the most effective and environmentally responsible tools for managing dense aquatic growth. By physically removing weeds rather than killing them in place, this method helps protect fish habitat, limit algae growth, and keep waterways open for recreation.

The Apple River Flowage’s ongoing success shows how local commitment, steady maintenance, and the right equipment can make a lasting impact on the health of a waterway.

Chemical Treatments: A Short-Term Fix That Makes Things Worse
Many lake managers turn to algaecides and herbicides to control harmful algae. On the surface, these treatments may look effective, but the reality is very different.

When algae are killed by chemicals, the cells release toxins directly into the water. The dead material then sinks, decomposes, and consumes oxygen—creating hypoxic conditions that stress or kill fish. Low oxygen also triggers internal nutrient release from sediments, fueling the very blooms that the chemicals were meant to stop.

Instead of restoring balance, chemical treatments can lock lakes into a cycle of recurring blooms and declining water quality.

Looking at the Surface Isn’t Enough
It’s common to judge a lake’s health by what can be seen at the surface—clear water, healthy oxygen levels near the top, or visible fish. But many lakes stratify, with deeper waters cut off from oxygen. While the surface looks fine, the bottom layers can be oxygen-depleted and nutrient-rich.

Fish crowded near the surface aren’t thriving—they’re escaping conditions that are deadly below.

Runoff Isn’t the Only Problem
Nutrient runoff from land is an important driver of algae, but it’s not the only one. Sediments at the bottom of lakes often act as storage banks for phosphorus and nitrogen. When oxygen levels drop, these nutrients are released back into the water, feeding new blooms year after year.

Focusing only on reducing runoff misses the internal nutrient cycle already at work inside the lake.

The Limits of Simple Metrics
Common tools like the Trophic State Index (TSI) are often used to measure lake health. But they mostly track surface-level data like clarity and nutrient concentrations. These numbers don’t reveal what’s happening in deeper waters, or how sediments and oxygen loss are driving long-term decline.

A Call for Smarter Lake Management
The misconceptions around lake health—and the overreliance on chemicals—are keeping many lakes stuck in poor condition. Chemical treatments may offer short-term relief, but they create long-term problems.

To break the cycle, management strategies need to focus on oxygen restoration, sediment nutrient control, and ecosystem balance. Prevention and smarter monitoring are also key to creating lakes that are resilient, healthy, and able to support aquatic life for generations.

Chemical Treatments: Lethal to More Than Just Mussels

The copper treatment was designed to kill mussels, but it didn’t stop there. Entire populations of aquatic life were hit hard. Native mussels, snails, and insects dropped by as much as 90%. Fish populations took a devastating blow too—most of the local sturgeon were wiped out along with other species.

On top of that, more than 7,000 pounds of copper settled into the riverbed, creating long-term toxicity risks for sediment-dwelling organisms. Instead of targeting only the quagga mussels, the treatment spread lethal effects across nearly the entire food chain.

A Partial Success at a High Cost

Despite the widespread losses, the treatment did not eliminate the mussels. Quagga larvae were still detected in the Snake River a year later, forcing another round of chemical use. Officials report that the infested stretch of river has shrunk in size, but containment is far different from eradication.

For millions of dollars spent—and with ecosystems damaged in the process—the results fall short. Many now see the effort as a failure, because the mussels survived while native species did not.

The Bigger Problem With Aquatic Chemicals

Copper and other aquatic chemicals may be approved for use, but they are far from safe. In a river system, they do not stay neatly in place. They travel downstream, settle into sediments, and continue poisoning life long after the initial treatment ends.

The Idaho case highlights the risks of relying on chemicals as a “quick fix.” They may knock back invasive species temporarily, but they also create lasting harm for native species, water quality, and ecosystem balance.

A Call for Smarter Solutions

Idaho’s quagga mussel response is a cautionary tale. We cannot treat complex waterways like controlled test sites. Before future treatments, agencies must consider alternatives that remove or manage invasive species without poisoning everything else along the way. Smarter strategies—such as mechanical removal, improved monitoring, or long-term prevention—are needed to protect both water quality and aquatic life.

Flint Lake on Valparaiso’s north side is in trouble. Invasive aquatic weeds, especially Eurasian milfoil, have become so overgrown that they’re even interfering with fish population surveys. During a recent Department of Natural Resources (DNR) survey, biologists had to stop two or three times just to clean the weeds off their boat’s propellers.

Herbicide Treatments: A Short-Term Fix with Long-Term Consequences

While treatments for Eurasian milfoil might seem like a good solution, they often come with serious environmental trade-offs. Herbicides do not actually remove the plants—they simply kill them where they grow. This leaves large amounts of decaying plant matter in the water, which can significantly reduce oxygen levels. As the plants rot, they consume oxygen that fish and other aquatic life depend on, potentially creating dead zones that are uninhabitable.

To make matters worse, the milfoil in Flint Lake is becoming more resistant to the most commonly used chemical treatments. And if the herbicide isn’t specific to milfoil, it can endanger beneficial native plants as well.

Native Plants: Critical for Young Fish and Water Quality

These native aquatic plants are more than just vegetation—they’re lifelines for young fish. “Anytime you damage these plants, you’re killing hundreds of thousands of babies,” DNR specialist said. Smaller fish use these plants to hide from predators and as feeding grounds. Destroying them reduces fish survival rates and upsets the balance of the ecosystem.

Mechanical Removal Isn’t a Silver Bullet Either

Even mechanical methods have their risks. Fragmenting Eurasian milfoil—chopping it up—can actually help it spread. Each small piece of the plant has the potential to take root and grow elsewhere in the lake.

A Call for Smarter Management

The situation at Flint Lake underscores the urgent need for responsible and effective aquatic plant management strategies. It’s not enough to kill the plants—we must remove them in a way that protects fish habitats, promotes water quality, and prevents further spread.

Water hyacinth spreads mainly by growing new plants from existing ones, creating dense clusters. It can also spread through seeds, though this is less common. First introduced into the lake through the Kagera River, the plant has become a serious problem. In 1996, satellite images showed that water hyacinth covered about 1% of the lake, and now it is estimated to cover as much as 3%.

Aquarius Systems, a company specializing in water management, has been selected for a project to remove the water hyacinth from Lake Victoria. Under the Lake Victoria Environmental Management Project (LVEMP), the company will cut and remove 1,500 hectares of the invasive plant over 12 months. This effort is funded by the Global Environmental Facility and the International Bank for Reconstruction & Development.

To tackle the problem, Aquarius Systems will use special equipment, including two “Swamp Devils” and one aquatic plant harvester. The Swamp Devil is a powerful machine that can cut through thick vegetation, including small trees. The harvester will collect and remove the cut plants. This method is a more environmentally friendly alternative to using herbicides, which could harm the lake’s ecosystem.

Managing Lake Victoria’s water quality is a long-term effort. The removal of water hyacinth is an important step, but more work is needed to fully restore the lake’s health. One possible solution is to turn the removed plants into compost for fertilizer. This approach could provide additional benefits to local farmers while helping to control the spread of water hyacinth.

This project is an example of how mechanical solutions can help manage environmental problems without harming nature. While there is no quick fix for Lake Victoria’s issues, this effort is a step in the right direction. People around the world are watching to see how this project unfolds, and it could serve as a model for future lake restoration efforts.

The main issues with wake boats include:

• Shoreline Erosion: The large wakes created by these boats can accelerate erosion along the shorelines, especially on smaller lakes with fragile ecosystems. This erosion can disrupt natural habitats, damage property, and increase sediment runoff, impacting water quality.

• Sediment Disturbance: Wake boats “plowing” motion, churn up sediment and tear apart aquatic plants, especially in small, shallow lakes. This stirs up nutrients like phosphorus, making the water murky, destroying fish habitats, and promoting algae blooms. The disruption also encourages invasive species, damaging the lake’s fragile ecosystem.

• Disturbance to Wildlife: The powerful waves can disturb wildlife, especially waterfowl and aquatic creatures. Sensitive species may be particularly affected by the increased wave action and boat noise.

• Safety Concerns: The large waves generated by wake boats can pose risks to other boaters, swimmers, and paddlers, who may find it difficult to navigate or remain safe in the choppy waters.

• Conflicts Among Lake Users: The use of wake boats can lead to tension between different groups of lake users. Anglers, kayakers, canoeists, and those seeking a quiet, peaceful experience on the water may find their enjoyment diminished by the waves and noise created by these boats.

In response to these concerns, some lakes and local governments have implemented regulations, such as restricting wake boats to certain areas or imposing limits on boat speed and the size of wakes that can be generated. However, balancing the interests of different lake users while protecting the environment remains a challenge in many Wisconsin communities.

31 Wisconsin communities now have ordinances restricting “artificial wake enhancement.” Mequon and Thiensville were the first, passing restrictions in 2009 along the Milwaukee River, banning boats from creating wakes by operating in a “bow-high manner” or at “transition speed,” which is key for wakesurfing.

Before the COVID-19 pandemic, only five such ordinances existed. From 2021 to 2023, 10 more were passed, and in 2024, 16 additional communities imposed restrictions. These 31 ordinances now affect nearly 200 lakes across the state.
