Proper Lake Management Keeps Your Resort Lakes Looking Beautiful

Proper lake management is the secret to healthy, sparkling, and beautiful water features at your resort. Let’s face it; when it comes to upscale resorts, every detail matters. Your guests expect more than perfectly manicured golf courses. Every lake and pond on your property speaks volumes about the care and attention you give to your property, and in turn, to your visitors.

Upscale hotels, resorts, golf courses, and casinos throughout the country know that meticulous lake management results in a healthy aquatic environment. The proper balance of fish, plants, aeration, and maintenance makes all of the difference. This, in turn, ensures that your guests always see sparkling and beautiful lakes, fountains, and ponds every time they visit.

To maintain the natural beauty of your lakes and ponds, you need to partner with a company that has extensive experience caring for water features from the most petite pond to the largest lake. Select a partner company that serves:
Homeowner’s Associations (HOA)

Keep Oxygen Levels Up in Your Lake with the Right Aeration System

The primary purpose of aeration in pond and lake management is to increase the oxygen levels in the water. There are different methods for doing this, including injecting air, mechanically mixing or agitating the water, or even injecting pure oxygen.

Destratification is a type of circulation that thoroughly mixes the water layers of different temperatures in the lake.

Here are the most common systems for lake aeration.

Air Injection (Diffuser Systems) – The most common method, air injection systems, consist of a compressor on shore delivering air through lines to the bottom of the lake.  The rising air bubbles cause colder water to rise and mix with the warmer water.

Mechanical Flow Pumps – A floatation platform and frame support an electric motor and a large propeller. The propeller pushes the water from the surface downward, setting up a circulation pattern.

Surface Spray Units – This lake aeration system consists of a float with an electric motor-driven impeller. The turning impeller pulls water up a long vertical tube and sprays it above the water’s surface in a fountain effect.

Impeller-Aspirator Systems – These consist of a float that supports an electric motor-driven impeller at the bottom of a hollow shaft that extends down toward the deeper water at an angle. The impeller propels the water into the air.

Pump-and-Cascade Systems – This lake aeration system is a large pump that moves lake water to the top of a ramp chute. The water cascades down the ramp and falls back into the lake.

The Four Main Types of Pond Weeds

It can be challenging to keep your pond weeds under control. You will first need to identify which specific weed is your main nuisance plant, as you wouldn’t want to start the wrong type of treatment. Additionally, some pond plants are beneficial to local and migratory wildlife.

When it comes to aquatic weed control, pond weeds can be easy to identify.


Algae are a common nuisance with no defined root system. Some, like planktonic algae, are microscopic, while others resemble land plants, except that they lack roots. It often floats on a pond’s surface in sheets but starts life at the pond’s bottom before floating to the surface.

Emergent Plants

Emergent plants are rooted plants often found along the shoreline. They stand above the surface of the water, like cattails. The stems or stalks of emergent plants are somewhat stiff or firm. You will want aquatic weed control for some common emergent weeds are alligator weed, water pennywort, and smartweed.

Floating Plants

True floating plants are not attached to the bottom of the pond. Some varieties can grow to over a foot in diameter, like the water hyacinth. Most have roots that hang in the water from the floating green portions. Duckweeds are a good example and form dense blankets that cover the surface of the water.

Submerged Plants

Of the underwater pond plants that require aquatic weed control, Hydrilla is one of the worst submerged weeds. It grows quickly and has long leaves and sharply serrated edges. Its leaves are quite rough to the touch. Flowers grown from their upper branches are translucent to white.

Why Use Aerators and Fountains for Ponds and Lakes

Adding air to a pond has a hugely positive impact on the ecosystem. It circulates water, disrupts mosquito breeding, adds oxygen for fish and other critters, and it helps prevent algae and other weeds. Aeration is by far the best value for money in terms of good pond health.

Aeration can come in many forms: aerators, fountains, windmills, circulators, and electric compressors. By far, the most common are pond aerators and fountains.

Pond aerators and fountains provide lovely visuals; this is true for fountains, especially, and aerators to a far lesser degree. Both mechanisms hang under a donut-shaped float and use a motor-driven propeller to shoot water up into the air. The main difference between a fountain and an aerator is that a fountain forces the water through a nozzle at high pressure, creating a specific display, whereas the aerator has no nozzle.

Using pond aerators and fountains do not provide the same oxygenation at the bottom of the pond as an air compressor, and usually isn’t as successful at fighting algae and weed growth. Pond aerators and fountains will circulate the top layers of water, keeping the pond surface free of scum and tree pollen. The benefit of this function is that they do not disturb the lower levels of pond or lake water, ensuring a better environment for trout and other cold-loving fish. Another advantage with pond aerators and fountains is that they do an excellent job of aerating shallow water bodies where you may otherwise need a large number of diffusers or an air compressor.

Keep the Pond in Your HOA Community Free of Weeds

When they overgrow, pond weeds can become unsightly and stunt fish growth.  Pond weeds usually start by someone adding plants to the pond, but they are then not managed and get out of control.

Here are a few possible methods to address weed control for lakes and ponds.

Many chemical options have warning labels, which state that for your safety and the environment’s safety, only 1/3 or 1/2 of the pond can be treated at a time due to the mass of dead, decaying weeds. More than that and it will risk a large scale fish kill.

There are tools to help make weed control for lakes and ponds easier, like extended weed cutters and rakes.

An eco-friendly approach is to use triploid grass carp, which eat weeds. However, there is a permitting process, and you need to do some research, as some species of weeds are not on their dietary list.

A Lake Bottom Blanket is another non-toxic option.  It covers and suffocates the weeds but does not suffocate the floor of the pond harming the smaller life.

Once overgrown pond weeds are addressed, then a proactive approach to weed control for lakes and ponds will ensure that they do not return. Installing a properly sized aeration system will provide oxygen in the water and help beneficial bacteria. You can add some “Muck and Sludge Remover” as well, to reduce the mucky bottom and even add some pond dye to the water to turn it a pleasant color.
