Description

Continuous Flow and Water Quality Monitoring Network in the Sacramento-San Joaquin Delta and Suisun BayThis is a Sources Sought Notice. The Bureau of Reclamation, Mid-Pacific Region, Bay Delta Office (BDO), is seeking businesses capable of providing ecological monitoring and research in the Sacramento-San Joaquin Delta to better document and understand the effect of the Central Valley Project (CVP) operations on hydrological, biogeochemical, sediment, and ecological characteristics of the system. Data collection will include the following:1. Hydrodynamic data: continuous water level, velocity, and flow (including both discharge and direction) that provides information about transport, mixing processes and water residence times. Hydrodynamic processes directly affect water supply, fish habitat, fish migration, and wetland inundation. The equipment used to collect hydrodynamic data include acoustic Doppler velocity meters and pressure sensors.2. Water-quality data: continuous temperature, specific conductance, and turbidity, all of which drive biological and ecosystem processes. YSI ExO2 multiparameter water quality sondes are used to collect these data. In addition to basic water quality parameters (temperature, specific conductance and turbidity), some stations measure continuous dissolved oxygen, pH, chlorophyll, dissolved organic carbon, and nutrients that impact aquatic biogeochemical processes (e.g. transformation rates, aquatic productivity, zooplankton growth) and are also in turn altered by many of these processes (e.g., photosynthesis, respiration, uptake). These data are collected by adding additional probes to the YSI ExO2 multiparameter sondes with the exception of the nitrate data which are collected using a SUNA V2. 3. Phytoplankton species composition data: the collection of discrete samples analyzed for phytoplankton enumeration, in addition to deployment of in situ multiparameter fluorometers that measure phytoplankton species composi...
