Can You Spot the Bloom?

Vancouver Lake Regional Park swim beach 8/21/2023

Vancouver Lake Flushing Channel 8/14/2023

Lacamas Lake "cove" Heritage Park 8/21/2023

Harmful algae is not always green! Look for a layer of green, blue, brown, or red on the water. Presence or absence of scum on the shoreline is another way to identify a bloom. A cyanoHAB is a harmful algal bloom (HAB) that creates cyanobacteria and can make people and pets sick.


Water temperature, sunlight, and nutrients are a few factors in algal blooms forming.


There's still lots of sun to enjoy in late August so be prepared and on the look-out for algae before you go in the water.

Causes of CyanoHABs

Answer: Vancouver Lake Flushing Channel and Lacamas Lake have active cyanoHABs in the images above. The image at Vancouver Lake Regional Park shows improving conditions and a dissipating bloom.
