Interagency Ecological Program: Discrete water quality monitoring in the Sacramento-San Joaquin Bay-Delta, collected by the Environmental Monitoring Program, 1975-2020.

The Interagency Ecological Program’s (IEP) Environmental Monitoring
Program (EMP) was initiated in compliance with the Water Right
Decision D-1379 (now mandated by Water Right Decision D-1641) and has
monitored discrete water quality and nutrients in the upper San
Francisco Estuary since 1975. The objectives of the EMP are to obtain
consistent and accurate monthly data at established monitoring
stations, provide and document information necessary to achieve
compliance with salinity, flow, and dissolved oxygen standards, and to
report this information for the purpose of management and conservation
of the upper San Francisco Estuary. While the EMP also collects
biological data, this dataset only includes the discrete water quality
and nutrient data collected by the EMP from 1975-2020.
