UC Davis scientists say they could see down 73.6 feet in 2004 – a 4% improvement from 2003.
Tahoe Regional Planning Agency spokeswoman Julie Regan says it’s encouraging news but warns against confusing the improvement with a longer trend, which is one of serious decline. "Of course any level of clarity of this magnitude is fantastic but we still are looking at a total average decline over the course of the last 30 years."
Lake Tahoe’s clarity declined from 99 feet in 1970 to a record low of 64 feet in 1997. Scientists say a number of factors have contributed to the lake’s loss of clarity over the years, ranging from air and water pollution to soil erosion and nutrients that fuel algae growth.
