The Water Picture: 1986-1993

February 25, 1993|NONA YATES

The record California dry spell has ended with a deluge. The 1993 rain total is still a few inches from surpassing the record set in 1978, but it has been enough to refill the state's network of reservoirs and assure Californians of a reliable water supply--at least until the next dry spell. Here is a look at the rainfall picture since the drought began.

After six years of below-normal rainfall, precipitation is approaching near record levels...

STATEWIDE PRECIPITATION, PERCENT OF NORMAL 1977: 4.5% 1986: 128% 1987: 61% 1988: 82% 1989: 86% 1990: 69% 1991: 76% 1992: 86% 1993: 155% . . . replenishing reservoirs that were getting dangerously low.

SNOWPACK WATER CONTENT, PERCENT OF NORMAL 1977: 27% 1986: 188% 1987: 47% 1988: 40% 1989: 72% 1990: 43% 1991: 85% 1992: 68% 1993: 140% Notes: 1993 figures are year-to-date totals, except snowpack, which is an estimate of what the April 1 season total will be.
