Water Quality includes a program of real-time telemetry, generally with 15-minute reporting to the California Data Exchange Center. In addition, the SJRRP initiated a program of manual water quality constituent measurements.

Water Quality Measurements
SJRRP measurements of total suspended solids, EC, pH, Turbidity, DO, bacteria, trace elements and pesticides at eight sites have been added to the Bureau of Reclamation Water Quality Database. Query All Program Information, Station Description field for “Interim Flows”.
Monitoring is organized according to the Interim Flow Water Quality Monitoring Plan.
Seepage Management Projects
Reclamation conducts water quality monitoring to establish the existing (baseline) quality of San Joaquin River (SJR) surface water in the vicinity of anticipated seepage projects in Reach 3 and Reach 4 of the Restoration Area, of surface water within irrigation canals that are potential receiving bodies for SJR seepage, and of groundwater in lands adjacent to the study reaches.
