What’s That Smell?
It’s that time of year again…when West Sacramento residents and travelers crossing the Yolo Causeway want to pinch their noses and ask “What’s that smell?"
According to the Sacramento Metro Air Quality Management District, it’s actually plants and growth rotting in the Yolo Bypass that dries out in the fall, and depending on the temperature and wind direction, can cause quite a stink.
The algae and wetland vegetation sinks to the bottom of water bodies and decomposes, creating sulfur dioxide and other foul-smelling gases.
Warm days and cool nights cause a thermal current, bringing smells to the surface.
Because of our proximity to the Bypass, West Sacramento gets the brunt of the strong odor.
