PERFORMANCE WORK STATEMENT (PWS)

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

1.0 Background

Reclamation operates and maintains the Central Valley Project (CVP) for the purposes of navigation and flood control; fish and wildlife mitigation, protection, restoration, and enhancement; agricultural and municipal and industrial water supply; power generation; and recreation. Reclamation’s mission is to perform these functions in an environmentally and economically responsible manner. To carry out this mission, Reclamation requires accurate and reliable data and information on the hydrodynamic, water quality and biogeochemical properties of the Sacramento-San Joaquin Delta (Delta) and Suisun Bay. Observational environmental data are used for: (i) real-time operation of CVP facilities, (ii) documenting long term status and trend measures of Delta ecosystem responses to hydrologic conditions, CVP operations and habitat restoration actions, and (iii) calibrating and validating hydrodynamic, sediment transport, biogeochemical, and ecological models.

The proposed tasks include high-frequency monitoring for flow, water quality (including chlorophyll, nutrients, and phytoplankton species composition), sediment, as well as biological responses at key locations in the Delta. 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.

For example, nutrient and phytoplankton dynamics are explicitly measured at select stations to improve our understanding of how physical dynamics, water quality, and landscape features shape the base of Delta food webs. These data will provide information about drivers linked to food quantity and quality as well as potential toxin production by harmful algae. Suspended-sediment monitoring provides an understanding of the sediment inputs and internal exchanges between Delta regions, locations of sources and sinks, and provides insight into the underlying cause of turbidity variability in the Delta. Suspended-sediment measurements also gage the availability of suspended sediment for existing tidal wetlands and for proposed large-scale marsh restoration efforts in the Delta.

Combined, these data establish the spatially and temporally rich data set needed for real-time operation of CVP facilities, understanding Delta ecosystem responses to hydrological conditions altered by the CVP, and evaluating restoration actions.

2.0 Purpose and Scope of Work

The scope of this project includes ecological monitoring and research in Sacramento-San Joaquin Delta to better document and understand the effect of CVP operations on hydrological, biogeochemical, sediment, and ecological characteristics of the system. Data collected will include:

• 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.

• 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). Together with hydrodynamic data, these parameters allow us to understand conditions that favor different phytoplankton species, which can determine the health of the food web, and whether conditions create suitable habitat for critical species. 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. Discrete samples for nutrients are chlorophyll concentration also collected for sensor validation and to analyze additional parameters.

• Phytoplankton species composition data include: the collection of discrete samples analyzed for phytoplankton enumeration, in addition to deployment of in situ multiparameter fluorometers that measure phytoplankton species composition at critical locations across the network to evaluate phytoplankton community dynamics that can inform the science and management of both beneficial and harmful algal blooms. Time-series data are collected using a multi-channel fluorometer (bbe Fluoroprobe).

• Sediment data are critical to assess and quantify suspended sediment distribution across the region and availability to existing and planned marsh habitats. Sediment concentration data are needed to transform turbidity data (a measure of water clarity) into suspended sediment concentration, a transportable quantity that can be used to compute suspended sediment fluxes and can be used in numerical models (turbidity cannot be used for either of these purposes).

Suspended-sediment concentration data are typically measured with the D96 sampler, but collection methods determined by field conditions.

For continuous monitoring stations, data are collected at high temporal resolution (every 15 minutes) across a network of stations in the Sacramento-San Joaquin Bay-Delta region. The recipient will provide various modes of data delivery including curated data summaries; interactive dashboards of flow, water quality, biogeochemical conditions and constituent fluxes; real-time posting of in situ field data and timely posting of discrete data to a public repository [e.g., Environmental Data Initiative (EDI), California Data Exchange Center (CDEC)]. These products provide information for evaluation and understanding of ecosystem responses to management actions in the Bay-Delta.

Additionally, the recipient will: obtain the required permitting for monitoring and research activities;

provide the necessary equipment, materials, supplies, and staffing to complete all tasks; conduct biological sample collection and processing (e.g., identification, enumeration); conduct data quality control and assurance, management and open access publishing; and serve as lead or co-lead on data analysis and reporting of results. These activities will be completed in collaboration with Reclamation biologists and natural resource specialists.
