Harmful Algal Blooms
Harmful Algal Bloom Monitoring
Algae observed in the lake?
Did you notice any algae at the lake site? Algae, when present in moderate amounts, is a healthy part of the lake community. Please survey popular recreation sites at the water body.
Types [of algae] observed?
Filamentous algae is “stringy” and like “cotton candy” It is harmless and can be picked up with a stick.
Algae in the water column: Tiny microscopic algae are often present in the water column, giving the water a
green (or brown) tint. Look for greenish colored water (L) or tiny clumps of algae
floating in the water column (m). Pea-green waters (R) are an indication of an algal bloom.
Floating scum (different than filamentous green algae) are almost always Harmful Algal Blooms. Follow “in-case of a bloom instructions”.
Harmful algal bloom suspected?
If your water is abnormally greenish colored, you observe many floating algal colonies or if there are any spilled-paint like scums present, you should suspect a harmful algal bloom. Follow the “Steps to Take if You Suspect a Harmful Algal Bloom” document to record your observations, photograph the bloom, and contact the authorities.
