Blue-green algae at Donkey Park

Donkey Park is a lake in Kauai County, Hawaii. Blue-green algae are not currently monitored at this water.

They can produce toxins that make people sick and can be rapidly fatal to dogs, so skip water that looks green, scummy, or like spilled paint, and keep children and pets out of it.
