Description: Description: Map of 10 ft. contour lines of equal elevation of groundwater levels of selected wells in the San Joaquin Valley, CA for Spring 2009. Well measurements were collected from January to May 2009 by the California Department of Water Resources (DWR) and cooperating water agencies and entered in DWR's Water Data Library ( The resulting point data were plotted in ArcMap 9.3.1 and contoured using Spatial Analyst at 10 ft. contour intervals.

Toggle Image Water Quality Conditions in the Sacramento-San Joaquin Delta 1970 - 1993 12/31/1996 (PDF, 11.71 MB)
Description: The upper estuary has been characterized as a dynamic system, changing as it responds to the intricate interactions of physical, chemical, and biological forces. This was reflected by the lack of a consistent long-term trend for most variables between 1970 and 1993. Among the physical variables that did demonstrate a trend, total exports, Secchi disk depth, and wind velocity increased over the period of record. The increase in Secchi disk depth was accompanied by a decrease in suspended and volatile solids. Among the biological variables that demonstrated a trend, chlorophyll a concentrations decreased in the southern and Suisun Bay regions, and diatoms decreased throughout the upper estuary.
