Florida is famous for its beautiful wetlands, but these natural treasures are threatened by hundreds of different factors, from the composition of bottom sediments to features in the surrounding landscape. The space where these environments meet provides valuable insight about the health and diversity of an aquatic ecosystem. This unique area is called the littoral zone.
The littoral zone is the down-sloping shelf of a pond or lake. This is the area that stretches from the high-water mark to the shore and into the area where sunlight penetrates through to the sediments at the bottom of a waterbody. Although the exact definition of littoral zone can change depending on the waterbody, it is generally considered the shallow area close to the shore in both saltwater and freshwater environments.
When healthy, the littoral zone looks like a miniature wetland. The beneficial plants that grow here often feature purple, white, yellow, or blue flowers that usually bloom all year long in Florida’s climates. These plants may include Golden Canna, Pickerelweed, Southern Blue Flag Iris, Fragrant Water Lily, and Florida Swamp-Lily.
The littoral zone or littoral shelf supports a large number of native plants and aquatic life. Because Florida’s aquatic species are so diverse, some plants can survive partially or completely submerged while others do just fine floating on the water’s surface. Waterbodies that support a wide variety of native plant species tend to provide more nutrients to the native wildlife that are key to maintaining cover and habitat. In addition to supplying food to ponds and lake fish, local plants help maintain balanced levels of oxygen and other key elements.
In addition to protecting the health of lakes or ponds, the littoral zone can enhance the aesthetic appeal of any Florida waterbody. When filled with thriving plants and wildlife, a well-tended littoral zone adds value to the shoreline and even the surrounding property.
A littoral zone helps improve water quality by fostering beneficial species that consume the excess nutrients that contribute to nuisance algae and invasive aquatic weed growth. Additionally, when located near a flow structure, the littoral shelf helps filter out the minerals and nutrients in water before it leaves the lake or pond. This improved water quality has the added benefit of keeping mosquitos at bay and reducing foul odors exuding from the water.
Littoral shelves also help maintain the shoreline and prevent erosion. The native plant roots hold the soil and make the banks more stable and durable, which in turn helps reduce the need for extensive restoration or dredging projects in the future.
Because the littoral zone transitions from dry land to the aquatic environment, it responds to natural and human influences and activities in the land ecosystem as well as the aquatic one. And because it is important for many industrial and recreational purposes, the littoral shelf is often drastically affected by human activities that amplify algal and weed growth, nutrient loading, overgrowth of invasive species as well as cause acidification and fluctuations in the water level. This underscores the importance of the littoral zone and littoral shelf maintenance for the health of lakes and ponds.
When properly established and managed, the littoral zone is less likely to require herbicide or algaecide applications. Recurring proactive management strategies such as nutrient remediation, biological bacteria applications, water quality testing, aeration, Oxygen Saturation Technology (OST), and other sustainable solutions can have a lasting positive impact in Florida’s delicate aquatic environments. A SOL Pro Annual Management program will help any property owner prolong the balance and beauty of their lake or pond’s littoral zone.

During the summer, we all look forward to recreational activities on local lakes and ponds; however, sometimes our plans are canceled due to unsightly, smelly, harmful algal blooms. Knowing a little about how HABs form can help us understand their health effects, ways to identify them, and strategies to prevent them.
Algae are a natural feature in many aquatic ecosystems. Most lakes have some algae growth on a regular basis, especially during the warm summer months, but it is crucial to stay on top of the algae development since blooms can happen quickly – before you know it, there are ugly floating mats on the lake’s surface. Likewise, certain species like cyanobacteria (also referred to as blue-green algae) can create concerning conditions by releasing dangerous toxins into the water.
Here are some signs that a bloom may be harmful:
Each bloom’s toxicity can vary and it’s hard to predict how dangerous a bloom will be as its toxicity changes daily. If the lake on your property looks like it may be developing dangerous levels of algae growth, take immediate steps. Not all blooms are toxic, and the only way to be sure that a bloom may become toxic is through laboratory testing. However, it can take a few days to collect and test samples, and by then, it may be too late.
Most often, harmful and toxic algal blooms occur because a lake or pond is not healthy. The lake may have an excess nutrient load due to the presence of too much phosphorus and nitrogen. When there are too many of these nutrients in the lake water, algae can overgrow or bloom.
A waterbody’s health can change year over year, depending on the weather and other factors in its surrounding environment. This is why a lake that was seemingly healthy suddenly experiences a bloom. This doesn’t necessarily mean the lake is destined for poor health, but it does indicate that there are imbalances that must be addressed.
Conditions that may change lake health and cause a harmful algal bloom include:
The toxins produced by harmful algal blooms can cause serious health impacts to pets, people, wildlife, and livestock. These health effects can range from skin irritation and rashes, gastrointestinal illnesses, neurological problems, and even death.
Once algae have overgrown enough to cause a large bloom, management can be challenging. Prevention is the best way to ensure harmful algal blooms don’t occur. Association boards and community managers can help prevent or minimize the risk of harmful algal blooms by taking the following steps:
To eliminate algae, the best course of action is to contact a freshwater management professional who can monitor and maintain balanced water quality and advise and apply appropriate management solutions. These professionals will ensure that the lake or pond’s water is clean and healthy and that the levels of algae remain at beneficial, manageable levels.

First of all, it is not healthy for them as they become dependent on people for food. The best food for ducks is what they eat naturally— algae, insects and a variety of plants which are abundant in our subtropical climate. Humans most often feed them bread and similar items. These have no nutritional value for the duck. Additionally, feeding by humans makes the ducks reliant on such hand-outs, too lazy to continue foraging for their natural dietary items and uneaten “human” food will rot quickly in warm weather.
Second, feeding ducks encourages them to use the neighborhood as their bathroom, leaving droppings on patios, sidewalks and porches. As a result, controversies frequently arise between residents who enjoy the birds and residents who consider them a nuisance. Even duck lovers have complained about the problem of duck droppings on the lawns, drive-ways, patios, and even in their swimming pools. This is not healthy for people, particularly for the children playing in these areas. Wild ducks can spread disease to humans. When small children, the elderly and persons with immune system problems directly handle newly-hatched chicks, they may be exposed to salmonella. Muscovies can also transmit disease to wild waterfowl. All confirmed outbreaks of DVE, also known as duck plague (a sometimes-devastating viral infection) in wild waterfowl have been linked to domestic ducks. Fowl cholera is another serious disease that is transmittable between domestic and wild waterfowl. Although we have had no major outbreaks reported yet in Florida, the potential for Muscovies to spread this disease to wild waterfowl is a biological concern.
DON’T: Feed ducks bread or junk food. Foods like bread and crackers have no nutritional value to ducks and can cause malnutrition and painful deformities if consumed too much.
DON’T: Leave uneaten food lying around. Leftover food in the water can rot and cause deadly algae blooms that affect local wildlife.
DON’T: Try to pet wild ducks. They may not appreciate your efforts!
Keep a respectful distance and remain nonthreatening, especially to ducklings who may become stressed or injured more easily.

Shoreline erosion can be detrimental to the health of your waterbody as well as the safety and value of your property.
Most communities throughout Florida utilize lakes and ponds to enhance the aesthetics of homes and golf courses, as well as support recreational opportunities such as boating and fishing for residents. The majority of these waterbodies were man-made for practical and functional purposes, such as capturing stormwater to prevent flooding or storing water to use for irrigation. Unfortunately, natural erosion of the shoreline is inevitable. It is an issue that only gets worse over time and should be addressed immediately, followed by consistent monitoring.
Shoreline erosion is a serious issue for waterbodies of all sizes and uses. It can degrade shoreline property, increase the risk of flooding, interfere with recreational opportunities, and threaten aesthetic appeal. In many cases, the deep cracks and gullies that appear can expose sprinkler systems, drainage pipes, and electrical cables, leading to costly repairs. Likewise, due to the effects of erosion, lakefront homeowners may find that their property decreases in size and value over time.
When slopes become too steep, the shoreline can also become unsafe for residents, children, pets, and recreationers. Steep slopes increase the risk of someone falling into the lake and being injured. The steepness of the slope can also make it hard for someone to get out of the lake when they fall in. This can pose a significant liability for HOAs, golf courses, commercial properties, and private homeowners.
Erosion has many natural causes:
The presence of nuisance fish and wildlife such as invasive armored catfish and otters that burrow into banks and cause them to collapse
Although these causes are natural, human activities can also increase the rate of erosion:
Despite the best efforts of HOAs, golf course superintendents, and municipalities, all waterbodies will experience erosion to some degree. However, there are many strategies to control or mitigate erosion.
Planting deep-rooted grasses and flowering vegetation will help retain, hold and stabilize the soil. This ground cover also helps to deter nuisance and invasive species from entering the aquatic ecosystem. It is imperative to use native plants rather than exotic species that are known to damage the habitat that nurtures beneficial fish, birds, and other wildlife.
Bioengineered erosion control technology is an excellent tool to restore shorelines and mitigate future erosion. Knitted ShoreSOX® and DredgeSOX® repurpose eroded muck by anchoring it to the shoreline for lasting stability. SOX solutions integrate naturally into the landscape and can be planted directly with vegetation for further erosion protection.
With riprap, rocks are placed over a filter blanket to keep the soil in place. Similar to riprap, root trap is achieved by covering the rocks with topsoil and installing native, deep-rooted plants that contain the sediment in place as they grow.
Bulkheads and retaining walls can be effective at controlling the effects of erosion; however, if not installed correctly, they run the risk of falling into the water or eroding from underneath and becoming unsafe.
Coir logs or fiber roll material can be installed to slow down the movement of the water or create a “pooling” effect that allows sediment to filter out. They can be made of natural or synthetic fibers or a blend of straw, coconut fiber, or polypropylene (plastic).

The grass carp has been introduced throughout the world for aquatic weed control. The grass carp was considered for introduction into the U.S. primarily because of its plant-eating diet, which was thought to have great potential for the control of aquatic weeds.
Wide-scale use of the grass carp in Florida and many other states from 1970 to 1984 was limited and closely regulated due to fears about its reproduction and negative impact on sport fish. Since the grass carp’s potential for causing such problems was evident, early research focused on developing a fish that would be non-reproductive but would retain the grass carp’s herbivorous diet.
Research with the grass carp resulted in the production of a sterile triploid grass carp, which has an extra set of chromosomes. The triploid grass carp is produced in the same way as the diploid, except that fertilized eggs are subjected to heat, cold, or pressure shock result in the formation of fish with an extra set of chromosomes for a total of 72. The extra chromosomes make these fish sterile.
The grass carp is primarily a “grazer”; it tends to feed on the surface and in shallow water. The ability of grass carp to consume and utilize aquatic plants depends on the size of both plants and fish. Additional factors which influence the feeding behavior of grass carp include their size, age, gender, and population density, and the species, abundance, and location of plants within a body of water.
In Florida, a permit is required by law for the use or possession of grass carp. Only grass carp certified as triploid can be used in an aquatic weed management program. Allstate Resource Management recommends triploid grass crap in combination with a lake management program.

At SOLitude Lake Management, we believe healthy, balanced waterbodies allow our clients to create meaningful experiences on and around their waterbody. We are dedicated to making water a more healthy and beautiful part of our world by utilizing sustainable management solutions and innovative technologies that improve water quality, enhance beauty, and preserve natural resources.
For many cities, lakes, ponds, and waterways are a major attraction and part of what makes living there so special. From the rivers to the beautiful lakes and ponds throughout communities and golf courses, water is central to everyday life. However, you may not have given much thought to what goes into maintaining all of these beautiful waterways.
Maintaining a lake is more complicated than you may realize. It requires ongoing water quality monitoring and management to help ensure the lake continues to thrive and that people can continue to enjoy it. Without regular management of your lake or pond, the waterway can become unusable.
Ongoing monitoring and maintenance is the key to maintaining a waterbody that meets your needs. This is why an annual management approach is so beneficial for any aquatic ecosystem. Learn more about year-round management and the benefits of a SOL Pro Annual Management Program. With regular professional oversight and care, you can enjoy your waterbody for years to come.
Freshwater ecosystems serve many purposes. They support irrigation, stormwater collection, drinking water, water sports, and recreational fishing. Regardless of their function, management is necessary to support the biodiversity and environmental health of the waterway.
Water can also have a significant impact on property values. In housing developments, no one wants to smell or look at an unsightly, overgrown lake or pond. That’s why it is critical for HOAs and apartment complexes to adequately manage their waterways.
Lake restoration is an important process in which a wide range of management techniques are used to restore a lake to its original state or to a state that better supports the health and well-being of the aquatic system, including plants and animals. It’s important to understand why problems, which often manifest as algae, occur before preventative solutions can be implemented.
The word “algae” often gets used informally as a catch-all term that can include a wide array of organisms that are not always closely related. Sometimes, when people refer to “algae,” they may actually be talking about cyanobacteria, also known as “blue-green algae” or “toxic algae.” It actually is not algae at all.
Cyanobacteria appear in several different forms. It can appear as hair-like filaments, slimy coatings on plants, or a green, soupy-looking substance suspended in the water column. Cyanobacteria can release toxins that can harm your waterway. The toxins are the cyanobacteria’s way of defending themselves against other competing organisms, but they can also harm fish, wildlife, pets, and humans.
Excessive runoff and pollution is a common source of this problem. This runoff can lead to nutrient loading that will eventually upset the balance of a waterway’s aquatic system. Grass clippings, pet waste, eroded sediment, and landscaping fertilizers all contribute to nutrient loading. Managing the conditions that contribute to nutrient loading is crucial to keeping the harmful cyanobacteria and nuisance algae in check.
In both ponds and lakes, aeration systems are used to increase the oxygenation and circulation of the waterway. A pond aeration system can be in the form of a floating fountain or consist of submersed diffusers strategically located at the bottom throughout the waterbody. Aeration helps improve the overall health of the aquatic system by converting nutrients to forms that do not sustain organic growth. Likewise, if muck development is severe, new tools like Oxygen Saturation Technology (OST) can be used to target dissolved oxygen to the bottom sediments where it will remain and aid in the natural digestion.
Unhealthy shorelines are a large contributing factor to nutrient loading. In addition to releasing sediment, unstable and eroded shorelines can allow stormwater runoff to flow directly into the water, polluting the ecosystem. SOX Solutions is a knitted mesh material that can be used to physically reshape and anchor the shoreline for many years of stability. Planting native, deep-rooted vegetation around the
Lakes and ponds suffering from chronic nutrient loading may be excellent candidates for proven nutrient-locking technologies like Phoslock and Alum. These products can help inactivate excess nutrients, making them unavailable for fueling nuisance plants and algae. Phoslock, specifically, is a lanthanum-modified clay that rapidly binds and permanently removes free reactive phosphorus from the water column shortly after application. It is also effective in locking up the phosphorus in the bottom sediments. This helps return the pond to its naturally beautiful state.
Dead algae, along with other build-ups of sludge and bottom sediment, can occur in your waterway. This is a natural process, but poor management can expedite this build-up. Biological treatments (which are like a probiotic for your waterbody) introduce naturally occurring cultures into the water. They digest undesirable organic muck and help clear excess nutrients from the ecosystem. This process can also help raise the dissolved oxygen levels in the pond and help beneficial aquatic plants, fish, and animals thrive.
Nutrient-rich muck and detritus can be removed physically with a hydro-rake, which is essentially a floating backhoe capable of removing up to 500 pounds of material in one scoop. These materials are then taken from the shoreline for off-site disposal. This process not only helps remove excess nutrients, but also helps restore lake and pond depth and volume – reducing flooding, cloudiness, and bad odors.
In urgent circumstances, herbicides and algaecides can be used to quickly eliminate nuisance algae and weeds. Lake and pond management professionals only use products that are registered with the Environmental Protection Agency (EPA) and formulated to specifically target the undesirable growth in your waterbody. However, herbicides and algaecides should only be used as a last-resort option when it is too late for preventative action.
Sterile triploid grass carp serve as a “biological control” option for nuisance aquatic vegetation. Triploid Grass Carp can help reduce the amount of pesticides required for the management of nuisance and invasive vegetation. Though EPA-registered aquatic herbicides play a key role in safe and responsible plant management, they should generally be viewed as a last resort option for stubborn infestations.
