Weed Control Tips for Summer Boating & Swimming

Aquatic weeds can go from a minor nuisance to a major disruption during peak summer months. Whether you're trying to launch a boat, take a swim, or just enjoy a clean view from the dock, unmanaged vegetation can get in the way.

From safety concerns to recreational limitations, keeping your shoreline and swim zones weed-free is one of the best ways to protect your lakefront investment and enjoy the season to the fullest.

Why Aquatic Weeds Get Worse in Summer

As water temperatures rise, many aquatic plant species hit their peak growth phase. This is especially true in shallow areas near the shoreline, where sunlight penetrates to the bottom and fuels aggressive plant growth.

Factors that contribute to rapid summer weed growth include:

• High nutrient levels from runoff or fertilizers
  
  
• Slow-moving or stagnant water
  
  
• Lack of routine shoreline maintenance
  
  
• Minimal competition from natural aquatic species
  
  

Without intervention, these conditions can lead to overgrown swim zones, tangled boat props, and restricted access to docks or launch areas.

Weed Removal vs. Weed Prevention

Controlling aquatic weeds requires both short-term action and long-term strategy.

• Weed removal provides immediate relief—essential for high-traffic swim areas, dock zones, or boat paths.
  
  
• Prevention helps reduce regrowth and keep your lakefront manageable throughout the season.
  
  

Let’s take a closer look at how to approach each.

1. Cut Back the Growth with Manual Tools

When weeds have already taken hold, mechanical cutting is one of the most efficient ways to clear them out fast.

The WeedShear is a V-shaped underwater cutter that slices through submerged vegetation with minimal resistance. It's ideal for clearing boat lanes or prepping swim zones before a busy weekend.

For larger areas or dense infestations, a powered tool like the Aquatic Vegetation Groomer (AVG) can be used. It works like an underwater trimmer, shaving weeds at the base and giving you more control over depth and coverage.

2. Rake and Remove the Debris

Cutting weeds is only part of the process, removing them is just as important. Leftover plant material can sink, decay, and contribute to future muck and weed growth.

The RakeZilla is a heavy-duty aquatic rake designed to haul out large volumes of cut weeds and debris. Its long tines and wide head make it ideal for pulling vegetation from the water and clearing it away from shore.

Raking after cutting ensures a cleaner finish, helps reduce nutrient buildup, and makes your lakefront more inviting for guests.

3. Maintain Open Water with Regular Grooming

Once your main zones are cleared, periodic grooming helps prevent regrowth. Light weekly maintenance, using the same tools, is often enough to keep things under control without letting weeds regain a foothold.

Focus on:

• Boat paths
  
  
• Swimming areas
  
  
• Dock and lift zones
  
  
• Around piers and shoreline structures
  
  

This consistent approach not only improves water usability but also helps reduce algae growth and sediment buildup over time.

Keep Your Lakefront Clean All Summer

Aquatic weeds are part of lake life but they don’t have to dominate your summer. With the right mix of cutting, raking, and proactive maintenance, you can stay ahead of growth and keep your shoreline clear, safe, and ready for fun.
