Blue-Green Algae Blooms in Eel River and Big Lagoon

This is a Blue-green Algae warning: There have been recent blooms on the Eel River and Big Lagoon. Stay out of areas where it has formed. Children and pets are particularly at risk. (See information on the effects below in the press release.)

Blue-green algae forms most often when high levels of phosphorous or nitrogen occur in warm, calm bodies of water.

Humboldt Health Alert Press Release:

Blue-green algae, also known as cyanobacteria, are simple plants found naturally in water and wet environments. Blue-green algae prefer warm stagnant nutrient rich water and are found most often in ponds, lakes, and slow moving rivers. Some species of blue-green algae produce toxins, so skin contact and ingestion can be dangerous. Children and pets are at the greatest risk of serious toxic effects from blue-green algae.

A bloom is a build-up of algae that creates a green, blue-green, white, or brown coloring on the surface of the water, sometimes occurring as mats or scum.

Although blooms can occur at any time of year, they occur most often in the warmer months between June and September.

In Humboldt County, Big Lagoon and the Eel River have seen recent blooms.

To stay safe, always assume that a blue-green algal bloom has the potential to be toxic. Do not drink or swim in water with scum layers or blooms.
