Abstract:

The State Water Resources Control Board (SWRCB) sets water quality objectives to protect beneficial uses of water in the Sacramento-San Joaquin Delta and Suisun Bay. These objectives are met by establishing standards mandated in water right permits issued to the Department of Water Resources and U.S. Bureau of Reclamation by the SWRCB. The standards include minimum Delta outflows, limits to Delta water export by the State Water Project (SWP) and the Central Valley Project (CVP), and maximum allowable salinity levels.

In 1971, the State Water Resources Control Board (SWRCB) established Water Right Decision 1379 (D-1379). This Decision contained new water quality requirements for the San Francisco Bay-Delta Estuary. D-1379 was also the first water right decision to provide terms and conditions for a comprehensive monitoring program to routinely determine water quality conditions and changes in environmental conditions within the estuary. The monitoring program described in D-1379 was developed by the Stanford Research Institute through a contract with the SWRCB. Implementation of the monitoring program began in 1972, as SWRCB, DWR, and USBR met to define their individual responsibilities for various elements of the monitoring program. In 1978, amendments to water quality standards were implemented and resulted in Water Right Decision 1485 (D-1485). More recently these standards were again amended under the 1995 Water Quality Control Plan and Water Right Decision 1641 (D-1641) established in 1999. The SWP and CVP are currently operated to comply with the monitoring and reporting requirements described in D-1641. D-1641 requires DWR and USBR to conduct a comprehensive environmental monitoring program to determine compliance with the water quality standards and also to submit an annual report to SWRCB discussing data collected.

The phytoplankton monitoring program is one element of DWR’s and USBR’s Environmental Monitoring Program (EMP) conducted under the Interagency Ecological Program (IEP) umbrella. The EMP also includes monitoring of water quality, zooplankton, and benthic organisms. The overall objective of the phytoplankton monitoring program is to determine the impacts of water project operations on the estuary. These impacts are interpreted by changes in phytoplankton diversity, abundance, and distribution associated with physical and other biological factors in the estuary.

Methods and protocols used in the collection of this data package
Description:

Field Methods

Phytoplankton samples are collected with a submersible pump or a Van Dorn sampler from a water depth of one meter (approximately three feet) below the water surface.

Samples are stored in 60-milliliter glass bottles. Two mL of Lugol's solution are added to each sample as a stain and preservative. All samples are kept at room temperature and away from direct sunlight until analyzed.

Description:

Laboratory Methods: EcoAnalysts, Inc.

Phytoplankton are identified to the lowest taxonomic level possible using the Utermöhl method and APHA standard methods (Utermöhl 1958, APHA 2012). An aliquot is allowed to settle onto a counting chamber for a minimum of 12 hours. The aliquot volume is adjusted according to the algal population density and turbidity of the sample. For the Estuary, the aliquot volume is usually about 10 ml. Aliquots are enumerated at a magnification of 630X using a Leica DMIL inverted microscope. For each settled aliquot, phytoplankton in randomly chosen transects are counted and photos are taken of the specimen, first encounter; measurements are made with an ocular micrometer. Taxa are enumerated as they appear along the transects. A minimum of 400 total algal units are counted, and a minimum of 100 algal units of the dominant taxon. For taxa that are in filaments or colonies, the number of cells per filament or colony is recorded. Length measurements are performed on 10 to 25 algal units of the dominant taxon, and up to 5 units of each minor taxon. The measurements taken are 1st greatest axial length, 2nd greatest axial length, and 3rd greatest axial length. From these measurements, biovolume is calculated for each cell measured. Biovolume equations are considered proprietary by the contractor but are based on the equations found in Hillebrand et. al. 1999. EcoAnalysts, Inc. processed data from 2008 to 2013, except for September 2013 and November 2013, which were contracted out to BSA Environmental, Inc.

Description:

Natural Unit Density Calculations (Organisms per mL)

Both contractors calculate natural unit density per unit volume of water using the same equation. Organism counts for each sample can be converted to organisms/ml using the following formula:

Organisms/ml = (C x Ac) / (V x Af x F)

where:

C = count obtained

Ac = Area of cell bottom (mm2)

Af = Area of each grid field (mm2)

F = Number of fields examined

V = volume settled, in ml

This simplifies to:

Organisms/ml = C / cV

where:

C = count obtained

cV = counted volume, in ml (cV = Ac /(V x Af x F))
