First-ever video from bottom of Lake Tahoe released

Researchers have captured the first-ever video from the bottom of Lake Tahoe, nearly 1,500 feet below the surface. The footage shows nutrient-rich particles that play a role in the lake’s ecosystem. Scientists from the University of Nevada, Reno say Tahoe’s deep-water mixing cycle—normally occurring every four to seven years—is showing signs of change. This process is key to keeping the lake healthy and its waters blue, raising concerns about Tahoe’s long-term environmental balance.
