Neglecting to stay on top of water quality issues may require reactive management approaches like herbicides and algaecides. Though these tools are effective, they are only treating the symptom of a bigger issue…
Proactive, natural solutions like aeration or beneficial buffers can help balance water quality, giving you the beautiful, clean water you deserve to enjoy.
Written by Industry Expert Gavin Ferris, Ecologist
I frequently use herbicides and algaecides in my line of work. Having attended college and graduate school to be an Ecologist, it isn’t something I thought I would do very often, but with the frequency of environmental problems that involve invasive flora, nuisance aquatic weeds and potentially-toxic algae, EPA-registered herbicides and algaecides are an invaluable tool. There are, however, times when their use is impractical, imprudent, illegal or impossible. Maybe the HOA or property manager prefers that herbicides not be applied to nearby waters. Perhaps the regulatory bodies in a given area aren’t permitting the use of certain products. Whatever the reason, sometimes this option just isn’t on the table. But how do we effectively manage algae and aquatic weeds without herbicides and algaecides?
I employ a simple concept that I call the algae triangle, though it works for all forms of vegetation.If you had the same fire safety lessons in elementary school, you may remember the Fire Triangle, which is based on the idea that three elements are necessary for fire: fuel, oxygen and heat. If you have enough of all three, you’ll ignite a fire. Eliminate any corner of the triangle, and the fire goes out. Similarly, if you have water, sunlight and nutrients, you’ll likely develop some form of algae or vegetation. If the triangle becomes too imbalanced, the resulting plant species can become a nuisance.
Obviously, in the lake management and pond maintenance field, we aren’t removing water from the equation, so establishing balance between each factor is the focus. Putting this concept into practice means understanding how sunlight and nutrients affect the ecology of the waterbody in question. Communities have several natural options to help mitigate against algae and aquatic weed growth, including limiting sunlight, improving water circulation and reducing excess nutrients.
If a stormwater pond receives full sunlight during the growing season, this directly impacts plants and algae by increasing water temperatures and providing the light necessary for photosynthesis. To prevent sunlight from penetrating the water column and stimulating the growth of deep submersed plants and benthic algae, water levels can be increased. Dredging is an effective strategy to increase the depth of a lake or pond, however, it is often the costliest project a community will ever face. Instead, proactive hydro-raking can help maintain existing water depths and prolong the need for dredging by removing unconsolidated muck and organic debris from the bottom of a lake or stormwater pond. Likewise, blue or black pond dye can be applied to reflect sunlight. Pond dye can enhance the aesthetics of a waterbody while simultaneously absorbing sunlight before it can penetrate the waterbody and fuel excessive plant growth.
In addition to thriving in water that receives lots of sunlight, algae and nuisance weeds also flourish in stratified waterbodies. A stagnant, sun-warmed layer floating on top of colder, deeper water can serve as a perfect habitat for undesirable species. Circulation with a diffused aeration system breaks this stratification and allows the water to mix more evenly, resulting in more consistent temperatures and less warming in the sunlit portions of the water. Aeration is also effective at improving the health of an aquatic ecosystem in a number of other ways, such as preventing oxygen depletion and fish kills, improving beneficial bacteria levels, and preventing the release of excess nutrients from the sediment. This brings us to the real meat and potatoes of preventative maintenance: nutrient management.
Phosphorus is the most important nutrient contributing to excess vegetation in lakes and stormwater ponds, and it can enter the water column in runoff containing lawn fertilizers, grass clippings, pet droppings, and waste from faulty septic systems. A number of nutrient reduction strategies should be considered if water quality tests reveal nutrient levels are too high. A professional lake manager can apply beneficial bacteria to the waterbody to utilize nutrients that would otherwise be available for plant and algae growth. Water quality can also be amended by using products that bind with phosphorus to keep it from becoming fuel for nuisance plants. Additionally, strategically planting desirable buffer vegetation around the shore of the waterbody can help to intercept phosphorus before it enters the water and is absorbed by unwanted vegetation. Your lake manager can help identify buffer plants that are native to your region.
When it comes to quickly and effectively managing nuisance aquatic weeds and algae, EPA-registered herbicides and algaecides can be very useful, and in many instances, they are the safest and most practical option available. Nonetheless, natural and proactive pond maintenance techniques can be tremendously effective at improving the health and appearance of almost any community waterbody before a problem occurs, which is why it’s important for homeowners associations and property managers to consider sustainable and holistic plant management methods whenever possible.

When you step into your lake, do you step into thick, foul-smelling muck? Maybe invasive weeds are hindering your view of the beautiful water?
Whether you enjoy fishing, boating, or swimming, nearly everyone has a lasting memory that centers around a great experience at a lake or pond. Unfortunately, the effects of time can slowly alter the appearance of a waterbody until it no longer resembles the place you fondly remember. Just as you age, lakes and ponds have a lifespan that is dependent on many factors, including vegetation growth, muck buildup, and more. If it is not properly managed, a body of water will eventually fill in with organic materials until it is no more than a small puddle. Luckily, there are strategies available to help restore the longevity of your favorite lake or pond.
Hydro-rakes can operate in most bodies of water, including those as shallow as 18 inches, and up to depths of 10 feet. A hydro-rake is best described as a floating barge containing a mounted backhoe arm (boom and dipper) with a York rake attachment. These attachments are used to scoop organic materials out of the waterbody, with the ultimate goal of improving water quality, increasing water volume, reducing bad odors, and creating a healthier, more balanced aquatic ecosystem. Most often, this entails the removal of decaying organic matter, leaf litter, tree branches, nuisance or invasive plant species, and other debris from the waterbody.
While native aquatic plants are often beneficial for lakes and ponds, the presence of certain nuisance and invasive species can cause the balance of an ecosystem to spiral out of control. Invasive milfoil, fanwort, and water chestnut, for instance, create dense mats in the water that block sunlight and exhaust dissolved oxygen. These invasive plants reproduce rapidly through both seed propagation and fragmentation. Native plants like cattails and water lilies can also be considered undesirable, depending on the extent of growth and the management goals for the waterbody. Lake and pond owners may utilize hydro-raking to physically remove nuisance and invasive plants. Depending on the undesirable plants present, a professional lake manager may recommend time frames throughout the year most conducive to plant removal via hydro-rake. An effective hydro-raking project will be completed at times when plant fragmentation is least likely in order to ensure lasting results.
A professional lake manager can design a hydro-raking plan that provides seasonal management of submersed plants and at least 2-3 years of management for floating leaf and emergent species. For particularly dense invasive species infestations, the strategic application of EPA-registered aquatic herbicides may also be necessary to ensure thorough management of the problematic plant. While hydro-raking serves as an effective management tool for the removal of rooted and submersed nuisance plant species, other species can be best managed with additional strategies, like mechanical harvesting, which targets algae and floating leaf plant species such as water hyacinth and giant salvinia.
Your waterbody does not need to be overrun with undesirable plants to experience the positive results of a hydro-raking project. Often, it is the best management solution for lakes and ponds containing thick bottom sludge or years of accumulated muck. A hydro-rake can collect up to 500 pounds of muck in each scoop and deposit it on the shore for off-site disposal. Or, the muck can be used to reshape crumbling shorelines using a patented bio-engineered shoreline system called SOX Solutions.
The removal of this muck can be a critical turning point for a lake or pond suffering from poor water quality, bad odors, flooding issues, or nutrient pollution. As leaves, grass clippings, trash, and other debris are swept into a waterbody by runoff during rainstorms, they begin to decompose. This causes them to release unnaturally high levels of nutrients that fuel invasive plant infestations as well as Harmful Algal Blooms, which can produce dangerous toxins with suspected links to degenerative diseases like Parkinson’s, Alzheimer’s, and ALS.
The removal of this nutrient-rich organic material can prevent undesirable plant and algae growth while improving water quality and volume. Ultimately, the best method to ensure your lake or pond maintains its health is preventative management. Biological dredging, for instance, utilizes beneficial bacteria to naturally eliminate excess muck at the bottom of a waterbody. This management tool is excellent for lakes and ponds in need of minor spot dredging or upkeep. Other proactive strategies aimed at reducing muck build-up and nutrient loading include buffer management, nutrient remediation, and aeration tools.
Hydro-raking can be extremely effective at removing plant matter, organic material, and debris, but mechanical dredging or hydraulic dredging can serve as transformative solutions that will increase depths and remove plant fragments, sediment, and other debris from the site. Though typically thought of as costly and more disruptive, dredging is often the best approach for lakes and ponds that have been neglected or misused for long periods of time. And with the help of bathymetric mapping technology, your lake management professional can help you quantify the rate of sedimentation and predict when dredging will eventually need to take place. With this information, you can better budget for and strategize your future dredging project. It’s never too early—or late—to begin implementing strategies that restore your waterbody for lasting beauty and enjoyment for years to come!

Discover how to naturally manage aquatic weed growth in your waterbody via hydro-raking or mechanical harvesting.
The answer depends on several factors, including the type of vegetation you want to be removed.
Both solutions allow you to naturally remove nuisance aquatic weeds with instant results, but which one is best for your lake or pond?
There is rarely one specific remedy for helping restore a waterbody. Often times, restoration includes a multiyear management program encompassing a combination of aquatic management tools and techniques, such as herbicide and algaecide treatments, nutrient remediation, aeration and biological augmentation. Mechanical removal is an additional management method that may be incorporated into a restoration program, and has a number of ecological benefits including nutrient mitigation, water circulation and open water habitat restoration.
Mechanical aquatic weed removal services encompasses two distinct management tools and approaches: aquatic weed harvesting and hydro-raking. While both provide ecological benefits, it is important to distinguish which option is better-suited for the specific management objectives of your lake or pond.
The aquatic weed harvester is a floating barge that cuts and effectively removes nuisance vegetation and algae from the surface of the waterbody. The plant material is collected and then offloaded, either into a container to be transported offsite or to a designated onshore compost area.
Mechanical lake weed removal offers an eco-friendly solution that does not create temporary water use restrictions during or after the work. For sensitive aquatic ecosystems, it can act as an alternative to herbicides. Mechanical harvesting can be an ideal management option for annual plants that are invasive or at nuisance levels. The aquatic weed harvester has been proven effective on water chestnut (Trapa natans), giant salvinia (Salvinia molesta), water soldier (Stratiotes aloides), and water hyacinth (Eichhornia crassipes).
The hydro-rake is also a floating barge run by two hydraulic paddle wheels, but is equipped with a 12-foot hydraulic arm with a rake attachment that is used to rake the pond bottom and remove detritus, organic sediment and aquatic vegetation with attached root systems. The hydro-rake, having no on-board storage, must offload the collected material directly onshore or onto a transport barge for removal.
Hydro-raking can be an effective alternative to herbicide and algaecide applications, but it has also proven effective in unison with these treatments. When managing emergent or floating leaf species, such as common reed (Phragmites australis) or water lily (Nymphaea sp.), herbicide application is often the first management approach, followed by hydro-raking. Hydro-raking is commonly utilized after control, to collect the plant biomass and associated root structure, negating it from contributing to the organic matter substrate below. This approach has proven effective on a number of aquatic plants such as cattails (Typha sp.), purple loosestrife (Lythrum salicaria), pickerelweed (Pontederia cordata), watershield (Brasenia schreberi) and Alligator weed (Alternanthera philoxeroides).
Hydro-raking can also serve as a more environmentally friendly and cost effective alternative to dredging. Additionally, if a lake or pond is periodically maintained through hydro raking, the need to perform a large scale dredge project may be negated, saving financial resources and prolonging ecological disruption in the process.
Both aquatic weed harvesting and hydro-raking collect plant biomass before it decomposes and contributes to the organic muck layer, maintaining or increasing overall water depth. In addition to the plant biomass, these mechanical options remove the associated nutrients (phosphorus and nitrogen) that contribute to increased plant and algae growth and, potentially, eutrophication.
These management techniques are used in a wide variety of projects on private, public and state waterbodies to help maintain or restore the open water space of shorelines, coves, inlets and outlets. Depending on the lake management objective and the target aquatic species for control, mechanical projects are usually part of a multiyear program. The next time you look out at your lake or pond, remembering its former attributes and beauty, consider investigating how mechanical lake weed removal services can be applied to help restore balance to your aquatic ecosystem.

The most important step is even before you have planted the first tree. You should select the right tree for the right location. You should always select trees that are wind tolerant and have good branch structure. Trees with good branch structure will have less overextended limbs, included bark and tree defects. Some trees handle decay from pruning better than others making species an important factor in the right tree. If your trees don’t have all the desired characteristics don’t worry you can still have the tree pruned by a Certified Arborist to remove or reduce the defects in the tree. So many people overreact and remove their trees out of fear of the unknown. This isn’t always necessary and is a waste of money.
You should always have a Certified Arborist inspect your trees on an annual basis. A Certified Arborist will be able to identify tree defects and make recommendations on corrective actions. Be sure the Certified Arborist you are working with has the TRAQ (Tree Risk Assessment Qualification) credential. Ask your Certified Arborist to provide you proof of his qualifications so you are sure your getting sound advice. Don’t be afraid to get a second opinion before you commit to having work done. We recommend you first work with a consulting Certified Arborist that doesn’t perform tree service work so they have no financial interest in the recommendations made to you.
So now were ready to prune. I know you have tons of questions and I’m here to help you answer them.
Should you thin your trees so the wind can flow through them? No this can lead to overextended limbs which can fail during wind events.
Should you top your trees? Absolutely not, this is one of the biggest mistakes tree owners make. Topping trees will lead to weak attachment points, heavier upper canopy growth and reduced tree vigor.
Should you have the dead, broken, cracked or overextended limbs pruned or removed? Yes you should. Overextended limbs are long and have most of the weight at the end. Cracked or broken limbs have a high likelihood of failing during wind events, Dead limbs can break off and impact important property.
Should I prune my palms so they will survive the hurricane apocalypse? No palms are adapt to wind storms and have zero benefits from hurricane pruning. You will want to have them inspected by a Certified Arborist so any defects can be pointed out to you.
What can you do to help your trees survive a windstorm event? Plant the correct tree for the location, Have a Certified Arborist inspect them annually, prune only when you have a valid reason to prune them, provide fertilization when necessary and most of all don’t fall victim to fear or bad information.
If you are in need of a Certified Arborist to inspect your trees or help you determine what the best course of action is for your trees please contact our Certified Arborist at http://www.arborologyinc.com. We will be glad to meet you and empower you on managing your trees.

When lakes and ponds exhibit problems like algae, aquatic weeds, bad odors, cloudiness, or muck development, it can prevent us from benefiting from the connection with nature that our waterbodies provide. Aquatic experts use a variety of techniques to diagnose the underlying issue. One of the most important tools is water quality testing. By analyzing water samples in a professional laboratory, scientists can identify the chemical imbalances that are preventing you from enjoying your waterbody to the fullest. Once data is collected, experts will implement tailored management solutions to restore the balance and beauty of the ecosystem. One natural and highly effective solution is Alum.
Alum has been a long-standing tool in our toolbox of lake and pond management solutions—and is a particular favorite of professionals who strive to use only sustainable maintenance practices. Alum (also known as Aluminum Sulfate) is used in a wide array of industries and applications such as drinking water management and wastewater treatments. In the lake and pond management industry, Alum is used to reset the chemical balance of aquatic environments to improve water quality. When water quality is enhanced, it creates an environment that is less hospitable to algae, nuisance weeds, and toxic cyanobacteria.
There is no one-size-fits-all approach to lake and pond management. This means that Alum may not be the right solution for each and every waterbody. Water quality tests help us understand the problems occurring under the surface and make this decision. Most often, Alum is deployed when water quality tests reveal unusually high levels of nutrients like Phosphorus, which is typically the root cause of undesirable organic growth.
Alum is applied to lakes and ponds as a white, powdery substance. As the Alum mixes into the water column, it binds with free-reactive nutrients, creating a cloudy trail behind the boat or a specially-designed application barge. After a short period of time, the particles sink to the bottom where they will remain inactive. Alum is considered very safe when applied by a professional and provides fast-acting results that can last for years. Almost immediately after an application is complete, the water column will become more clear. Over the course of days and weeks, the water quality improves.
Once the waterbody is restored to more balanced conditions, it’s important to prevent future nutrient loading by addressing the external sources of Phosphorus. Trash, pet waste, fertilizers, motor oil, sewage, and yard waste are often to blame. They can flow into lakes and ponds during rainstorms. Rainfall and weather events can also damage the shoreline, causing nutrient-rich soil and plant matter to crumble into the water. Stakeholders can slow this problem by establishing a robust vegetative buffer around the shoreline. Professionals recommend using native plants that grow approximately 18 inches high and develop complex root systems to naturally hold soil in place. If shorelines have sustained significant damage over the years, it may be necessary to completely rebuild them using bioengineered mesh technology that can be seeded with the grass and buffer plants following installation.
Alum is not the only natural substance that removes nutrients in the water column. Solutions like Phoslock and EuroSORB work similarly to target Phosphorus.
Phoslock is a lanthanum-modified clay that binds with excess phosphorus, chemically changing its composition so that they can no longer support weeds and algae. EutroSORB, on the other hand, is a filtration technology that captures nutrients in the water column. It is particularly effective in waterbodies with significant movement and mixing, such as stormwater ponds, streams, and canals. Once the filter is fully saturated with phosphorus, it is pulled from the water for disposal. In some cases, experts may also choose to use an aqueous form of EutroSORB that can be poured or sprayed on the surface, or applied via subsurface injection.
Your lake and pond management professional may consider a number of factors when choosing which of these three nutrient remediation products to implement. These may include your waterbody’s size, location, use, pH, dissolved oxygen concentration, muck level, and degree of water movement.
The well-being of our aquatic environments reflects our own. Science shows that humans are happier, healthier, and more relaxed when spending time around beautiful water. Nutrients are the building blocks that help create these amazing ecosystems that delight us, but it’s necessary to maintain them at balanced levels as nature intended. Alum is one of many eco-friendly tools employed through an annual maintenance program. Like most solutions, it is most effective when used proactively. Click to learn more about the benefits of Alum and the important role it plays in a year-round management plan.
