A large plankton bloom can be seen spread across Puget Sound from Tacoma to Edmonds, the Washington Department of Ecology said.
They tweeted out photos taken from a helicopter over the non-toxic bloom.
This bloom is earlier than usual, the department said, but last week's sunny weather provided the algae with a better environment to grow.
The Department of Ecology advises people should not swim in the tomato soup-like water. Most blooms are harmless but toxins can make people sick if exposed to high enough levels.
