While there are many benefits to lake weeds and algae, extreme proliferation tin can crusade many problems. When lake weeds cover more than than 25% of the lake surface information technology is considered dense growth. ^[1] This can interfere with water recreation, such every bit boating and swimming. It can also interfere with fishing by producing a foul taste and odour in the water. Most chiefly, dense lake weed growth can crusade major fish kills by depleting oxygen in the water at nighttime. ^[2] Make sure to take the proper command measures in your lake or pond to ensure a safe and flourishing aquatic environment. Remember, aquatic vegetation is an important part of the ecosystem. If algae and underwater vegetation accept taken over your pond or lake, use controls to restore balance without removing all of your vegetation.

Design your lake properly. Many species of lake weeds flourish when they can take root in underlying soil. ^[3] You can prevent this by creating steep banks on the border of your lake or pond, that descend directly into deep waters. ^[4]
- Consider constructing lake banks with a 3:ane form that descend into a h2o depth of 5ft. This strategy will prevent submersed plants from rooting in the lake, but it will not help with algae or free floating plants.
2

Keep your lake deep. Brand certain that your lake maintains a depth of two-3ft at its most shallow point.^[5] This will help prevent weeds from taking root if they go on to proliferate throughout your lake or pond. Keep in mind that this will only work for rooted weeds, not algae or free-floating plants.

3
Create a buffer zone around your lake. Lake weed proliferation is usually caused past an overabundance of nutrients in the surrounding soil. The runoff from fertilizer in the soil feeds these lake weeds and causes them to grow in big numbers. Create a riparian buffer zone by planting 100ft of natural plants or trees between your fertilized land and your lake to prevent runoff from entering the lake. Choose plants that will prevent erosion and that practise non require any chemicals to be practical.
- If yous accept livestock, nutrients from their feed and brute waste material may likewise enter runoff and cause weed proliferation. Consider building a debate around your livestock or keep them at to the lowest degree 100ft away from the lake'southward edge. ^[half-dozen]
4
Be proactive. Once you notice a significant lake weed event, exist sure to address it every bit shortly as possible. Continual overgrowth volition lead to more serious weed problems. The more you lot allow the weeds to grow, the more than expensive and time-consuming it will be to address the problem at a later date.
- If you notice besides many ducks or feeding fish effectually your lake, you may desire to take steps to reduce their presence. Their waste can contribute to the growth of weeds.

1
Use a benthic barrier. A benthic Barrier is a sheet that lays on the lesser of the lake preventing sun from reaching the lake bottom and so it kills lake weeds it targets. This is a non chemic reusable product that is safe for fish.
- Some vegetative growth is necessary for the wellness of the lake. If you use a benthic barrier, go out some area uncovered to allow for natural vegetative growth.
- Don't cover fish spawning or bird nesting areas.
2
Remove weeds by hand. Yous tin can easily cut up lake weeds from the roots, collect the cut weeds, and remove them from your lake or pond. They tin be cutting with a sickle or pulled up by hand, then removed from the h2o with rakes or hoes. ^[7]
- Almost lake weeds are perennials, significant they volition go along to sprout throughout the season due to underwater roots. Y'all must remove them from their underlying roots in social club to be properly command them. ^[8]
three
Use weed removal devices. Depending on the size of your lake or pond, and the weeds you are trying to remove, you lot may need an underwater or motor-driven device. Controlling lake weeds by mitt can exist labor intensive and hard, as these weeds usually grow back quickly.
- Motor-driven underwater removal devices can help cutting lake weeds loose under water, like water lilies and h2o milfoil. ^[9] There are as well aquatic weed harvesters that collect weeds for removal. Motor-driven devices often get out cutting-upward weed fragments in the water. New weeds may grow from these pieces so exist careful when removing weeds this way. ^[10]
- For surface algae in smaller bodies of h2o, water pumps can circulate the acme layer of water to forbid algal scum from settling.
- Mechanical control of lake weeds can be likened to mowing a lawn. These devices will trim the weeds, simply it is a temporary solution. ^[11]

Dredge and deepen the lake. If the weed problem is severe, and weeds comprehend over 25% of the lake surface, consider dredging and deepening the lake. This will remove existing weeds and the bottom layer of sediment, too as any underlying nutrients that cause weed proliferation. Dredging and deepening volition reveal a layer of food-poor soil, limit the amount of sunlight weeds are exposed to, and make information technology more difficult for weeds to take root. ^[12]

ane
Choose the correct herbicide. It is necessary to properly identify the weed earlier purchasing herbicide. Different species and types require different herbicides. If you are unsure of the weed, telephone call your county extension role or an herbicide dealer to make sure you buy the effective herbicide. ^[13]
- Make sure you understand the effects and implications of applying an herbicide before doing so. Read the label on your herbicide to understand the restrictions and await time on boating, swimming, and fishing before applying. This may be an of import cistron when choosing an herbicide. ^[14]
- Herbicide comes in both liquid and solid grade, as sprays or granules.
- For algal weed control, consider using copper sulfates or copper chelates, such equally Cutrine Plus. These can exist applied directly to the infested area as per the instructions on the label. ^[fifteen] For certain submersed plants, such as swimming weeds, and free-floating plants, such as duckweed, consider using a diquat or fluridone. Rooted-floating plants, such as water-lilies, and emergent plants, such every bit cattails, are best treated with glyphosate. ^[16]
- Cheque your local and state regulations earlier using herbicides in a body of water. Permits are required for some types of applications.
2
Employ nether the proper conditions. Herbicides are best applied in late jump when plants are youngest and weakest. If you wait until belatedly summer when vegetation is thick, you risk major fish kills past depleting oxygen all at once. ^[17]
- Apply when h2o temperatures are in the upper 60s (Fahrenheit). Herbicides do not work effectively when the water is besides common cold. ^[18]
three
Dose properly. Make sure that yous are using the proper dose when applying herbicide. The herbicide label volition depict how to calculate dosage. Dosage is usually measured based on acre-feet, which tin be determined past multiplying the surface area acreage past the boilerplate depth. The label will so tell y'all how much to apply based on this measurement. ^[19]
- Never apply a larger dose than listed on the label. ^[twenty]

Reapply as needed. Herbicides volition need to be reapplied in subsequent years to come. Underlying seeds are unaffected by herbicides and will therefore emerge the adjacent year despite initial treatment. Make sure to go on to apply in the spring to treat any structures that lay dormant in the winter. ^[21]

Check your local laws. Depending on the type of biological control that you use, you may need to get a allow from your local department of wild animals or agriculture. Some species that can control lake weeds are considered invasive in detail areas, and yous may not be allowed to innovate them. E'er learn what your local laws are before introducing a new animate being or fish into your lake.^[22]
2

Introduce swans to the lake. Mute swans can be released onto small lakes. As they feed on both submerged plants and algae, they may be ideal to control vegetation. Proceed in mind that swans require extra care, husbandry, and protection from predators.^[23]
3
Release grass carp into the lake. Also known as the white amur, grass carp feed on the submersed plants in your lake. They are usually introduced into a lake to control vegetation. Go on in mind that grass carp will consume about any submerged vegetation, non just invasive species or weeds.
- Grass carp volition not help much with duckweed or watermeal.
- It is recommended that you stock 15 to 30 fish per acre of lake. Get carp that are at least ten or twelve inches long.^[24]
- Grass bother tin can exist invasive. Check your local laws to make sure that you are allowed to employ them as a biological control before you release them into your lake.
4
Research which insects may be helpful. If you want to target a specific weed, y'all may wait into using insects every bit course of biological command. You will need to find insects that are host-specific; this means you pick a species of insects that will only eat the specific weed that you want to remove. You can research your particular weed to see if there is an insect species that may help. You might also reach out to your local section of wildlife or agriculture, Baneful Weed Command Board, or an ecologist.
- Exercise non release not-native insects until you have verified that they will merely consume the constitute in question and that they will take no other touch on your local ecosystem.

Article Summary X

To kill lake weeds, try laying a benthic bulwark on the bottom of the lake. A benthic bulwark is a sheet that prevents sunlight from reaching the bottom and kills any weeds there. If you use a benthic barrier, leave some areas uncovered to assistance underwater plants abound. Alternatively, employ a motor-driven underwater removal device, which cuts back the weeds similar a lawn mower. Yet, keep in listen that this doesn't forbid weeds from growing back. You can also utilize an herbicide to kill the lake weeds. For algae, consider using copper sulfates or copper chelates. For swimming weeds and gratuitous-floating plants, similar duckweed, use a diquat or fluridone. It's best to apply an herbicide in late spring when plants are youngest and weakest. However, keep in mind that herbicides can potentially be dangerous to fish and other wildlife.
