Today, the UC Davis Tahoe Environmental Research Center and Tahoe Regional Planning Agency released findings from the 2025 Lake Tahoe Clarity Report, which showed annual average clarity — or how deep a 10″ white disk can be lowered into Lake Tahoe before it becomes invisible from the surface — was statistically unchanged compared to the year prior. This continues a trend since the late 1990s of relatively stable, but not improving, Lake clarity.
After decades of steady water clarity loss in the latter half of the 20th century, organized efforts by Keep Tahoe Blue and other partners in Tahoe’s Environmental Improvement Program (EIP) helped stabilize Lake Tahoe’s world-famous water clarity. EIP projects to restore damaged ecosystems — especially in the Upper Truckee River watershed, Tahoe’s largest tributary — have been effective investments. As have policies to limit urban runoff and improvements to stormwater treatment infrastructure.
