"Thanks to the bi-state partnership, Lake Tahoe is one of the most protected watersheds in the nation," TRPA Executive Director Julie Regan said. "The science community has played a pivotal role in the drive toward environmental restoration, and we're proud of the progress we've collectively made on Lake Tahoe's clarity over the decades. What happens on the land here affects the lake, and we continue to look to science to inform and prioritize Tahoe's restoration projects."
