It is world-famous for its spectacular setting, and now people trying to protect Lake Tahoe’s beauty have added something new underwater to help keep it crystal clear: a “bubble curtain.”
Millions of tiny bubbles are pumped up from a line placed at the bottom of the Tahoe Keys. From up above you can see the bubble curtain in a V formation. The bubbles bounce out small invasive plants threatening to turn Tahoe’s crystal-clear blue water green.
