Continuous Flow and Water Quality Monitoring Network in the Sacramento-San Joaquin Delta and Suisun Bay

Description / purpose

High-frequency monitoring for hydrodynamic (stage, velocity, flow), water quality (including chlorophyll, nutrients), sediment, and phytoplankton at key locations in the Delta (Figure 1). The physical properties monitored by the fixed-station network are the primary drivers of the habitat conditions and biological responses that management actions are designed for. Combined, these data establish the spatially and temporally rich data set needed for real-time operation of water export facilities, understanding Delta ecosystem responses to hydrological conditions, and evaluating restoration actions.
