Lake Tahoe, CA, Surges with 16 Billion Gallons of Water Since February 15 as Storms Boost Levels - SnowBrains

Lake Tahoe has seen a dramatic influx of water in recent weeks, with approximately 16 billion gallons added to the lake since February 15, according to the U.S. Geological Survey-the equivalent of roughly 90,000 Olympic-sized swimming pools. This large bump has nudged the water gage height upward from about 7.5 feet to 8 feet on the lake's measuring station, reflecting substantial gains in the basin's water supply as winter storms continue to unload precipitation across the region.
