Magnitude and frequency of the floods of January 1997 in northern and central California; preliminary determinations
Preliminary determinations of the magnitude and frequency of peak flows resulting from the storms of December 1996 and January 1997 were made at 292 streamflow gaging stations located in 45 counties in northern and central California. Peak flows were the largest on record at 106 stations, and recurrence intervals were greater than 100 years at 32 stations. Two separate frequencies were...

Comparison of 1972 and 1996 water levels in the Goleta central ground-water subbasin, Santa Barbara County, California
Ground-water levels for 1996 were compared with 1972 water levels to determine if a "drought buffer" currently exists. The drought buffer was defined previously, in a litigated settlement involving the Goleta Water District, as the 1972 water level in the Central ground-water subbasin. To make this deter mination, a network of 15 well sites was selected, water levels were measured...
