Joe Blondia: Algal Blooms are a Natural Part of Spring

by | Mar 20, 2025 | Education, News, Watershed Trivia

There is lots happening in the spring in the Glen Lake/Crystal River Watershed. Birds are migrating, animals are coming out of hibernation, and diatoms (also known as algae) are growing in our water. 

You may see what looks like “clumps” floating in the water. These are formed when diatoms attach to the bottom of lakes or rivers. They release a little strand of mucus, and it traps other things in the water, and over time, this forms what looks like “clumps” of a variety of diatoms. With wind and currents, they eventually break off and float in the water.

This is a perfectly natural process, so don’t be alarmed if you see them!
