Is Your Lake Overeating? The Simple Science of Eutrophication

What Happens When Algae Take Over?

The first visible sign of eutrophication is often an algae bloom. The water may appear bright green, cloudy, or covered with floating mats of algae. While this may seem like only a cosmetic problem, algae create several serious issues.

They block sunlight from reaching underwater plants, preventing them from producing oxygen through photosynthesis. As algae die, bacteria begin decomposing the organic material, a process that consumes large amounts of dissolved oxygen in the water. This chain reaction can leave fish and other aquatic organisms without the oxygen they need to survive. You don’t have to wait until this happens—be proactive about maintaining your lake to avoid more costly issues down the road. You can work with a lake services company that offers detention pond maintenance and other services.

The Problem with Low Oxygen

Healthy lakes contain dissolved oxygen that supports fish, turtles, insects, and beneficial bacteria.

During advanced eutrophication, oxygen levels can drop and create what scientists call hypoxic conditions. In severe cases, fish kills may occur because aquatic animals simply cannot get enough oxygen.

Low oxygen also affects the entire food chain, reducing biodiversity and altering the natural balance of the ecosystem. Some of the warning signs you’ll notice when dealing with low oxygen include water odor, odd fish behavior, algae swarms, and water color changes. Reach out to a company offering lake services and retention pond maintenance to inspect your lake and offer solutions.

Can Eutrophication Be Prevented?

In many cases, yes. A good place to start is reducing the amount of nutrients entering waterways. Simple steps you can take include:

• Applying fertilizer only when necessary
• Avoiding fertilizer before heavy rain
• Maintaining septic systems regularly
• Planting native vegetation along shorelines
• Preventing grass clippings and leaves from entering storm drains
• Controlling soil erosion on construction sites and farms

Communities also play an important role by improving stormwater management and wastewater treatment. If you need professional help, consult with a company specializing in retention pond maintenance.
