4.3.3.3 San Joaquin River
The San Joaquin River at Fremont Ford and at Hills Ferry will be sampled on a weekly basis. Weekly samples should adequately characterize temporal variations and provide an adequate assessment of the changes in water quality in the San Joaquin River as a result of continued discharge of drainage (Hills Ferry) and from the removal of drainage (Fremont Ford).
A daily composite sample will be collected at Crows Landing. This frequency is necessary for evaluation of compliance with water quality objectives. A weekly grab sample will also be collected for quality control purposes.
