The following publications are available online. - Sources
of Salinity in the South Sacramento-San Joaquin Delta, May 2007. Division
of Operations and Maintenance, Environmental Assessment Branch. This report documents
discharges on waterways flowing to the State and federal export sites from the
San Joaquin River via south Old River and Grant Line Canal. The discharges are
mostly agricultural but also include four National Pollutant Discharge Elimination
System (NPDES) facilities, urban runoff, and groundwater effluence. The discharges
are saline and measurably raising the salinity of water flowing to the export
sites from the San Joaquin River.
- Water
Quality in the State Water Project, 2002 and 2003, July 2007. Division of
Operations and Maintenance, Environmental Assessment Branch. This report describes
water quality in the State Water Project during 2002 and 2003. State Water Project
facilities include the Oroville complex, California Aqueduct, South Bay Aqueduct,
North Bay Aqueduct, and four Southern California reservoirs. Trend analysis report
focused on drinking water parameters-of-concern such as salinity, organic carbon,
and bromide. Water quality in south Delta exports (California Aqueduct and South
Bay Aqueduct) was relatively good during 2002 and 2003. Salinity was low to moderate
for most months of each year. Seawater intrusion - with the resulting elevation
in salinity and bromide - was evident during the last five months of 2002 and
the last three months of 2003. With the exception of one month, organic carbon
in both aqueducts was 5.2 mg/L or less. North Bay Aqueduct exports exhibited relatively
high levels of organic carbon and turbidity. Water quality in the Oroville complex
and upper Feather River reservoirs was excellent, as usual, with non-detectable
to low levels of minerals, nutrients, and most minor elements.
- Factors
Affecting Total Organic Carbon and Trihalomethane Formation Potential in Exports
from the South Sacramento-San Joaquin Delta and Down the California Aqueduct.
Organic carbon in the California Aqueduct. Total organic carbon (TOC) and trihalomethane
formation potential (THMFP) were assessed in water exports from the south Sacramento-San
Joaquin Delta (Delta) at Banks Pumping Plant, the Delta-Mendota Canal (DMC), and
further down the State Water Project's California Aqueduct.

Joaquin Delta. California Aqueduct Salinity Report, 2004. This report describes
factors affecting the composition and salinity of exports from the south Sacramento-San
Joaquin delta.

of the California State Water Project - Appendix E 1999 Water Operations in the
Sacramento-San Joaquin Delta This is an annual publication that documents
SWP operations in the Sacramento- San Joaquin Delta. Appendix E also reports on
water quality, Delta flows, and the salvage and loss of federally threatened and
endangered fish at Delta facilities. This report covers 1998 water year, from
October 1, 1997, through September 30, 1998.
- Assessment
of MTBE In State Water Project Waters, April 1999. This report summarizes
the results of MTBE monitoring conducted in 1997 on eight reservoirs in the California
State Water Project. The main objectives were to evaluate MTBE loading from boating
activities during summer holiday weekends and to define MTBE concentrations in
the reservoirs. The 47 page report includes 25 Figures and 31 Tables.
