Harmful Algal Blooms in Michigan

Harmful Algal Blooms in Michigan

Harmful algal blooms (HABs) are a growing concern for lake and pond owners across Michigan. These blooms can reduce water quality, impact recreation, harm aquatic life, and create potential health risks for people and pets.

What Are Harmful Algal Blooms?

Harmful algal blooms occur when algae, most commonly cyanobacteria (blue-green algae), grow rapidly and accumulate near the water's surface. Blooms often appear as green scums, floating mats, or discolored water.

While algae are a natural part of aquatic ecosystems, excessive growth can create serious water quality issues. Some cyanobacteria can also produce toxins that may be harmful to humans, pets, and wildlife.

What Causes HABs?

Excess nutrients, particularly nitrogen and phosphorus, are the primary cause of harmful algal blooms. Common nutrient sources include:

• Fertilizer runoff

• Stormwater runoff

• Agricultural drainage

• Pet waste

• Decaying vegetation

• Waterfowl activity 

Warm temperatures, abundant sunlight, and stagnant water further encourage bloom development.

Why Are HABs a Problem?

Dense algae blooms can reduce water clarity, create unpleasant odors, and interfere with swimming, fishing, and boating.

As blooms die and decompose, they consume oxygen in the water, which can stress fish and other aquatic life. If toxins are present, contact with affected water may pose risks to people and animals.

Preventing Harmful Algal Blooms

The best way to reduce harmful algal blooms is through proactive lake management. Effective strategies include:

• Reducing nutrient runoff

• Installing shoreline buffer plants

• Monitoring water quality

• Managing aquatic vegetation

• Using pond and lake aeration systems

Aeration helps improve circulation, increase dissolved oxygen, and support healthier water conditions.
