Autumn is a lovely time of year when pumpkins dot doorsteps, the weather is warm and clear, and leaves change from green to red. It’s also the time of year when the levels of toxic algae in Watsonville’s Pinto Lake skyrocket, stimulated by those same sunny days.

For decades, Pinto Lake has experienced a seasonal population explosion of single-celled organisms called blue-green algae, or cyanobacteria. They flourish in the spring and summer in the warm, shallow waters. Some types produce deadly liver toxins that can sicken people and kill pets and wildlife. The toxin levels are often low, but they are also highly variable, spiking in the fall. Though the problem is ongoing, the lake recently set records for its toxicity and is bringing Watsonville national attention.
