The 2-Gates Project proposes an alternative management strategy to achieve protection of the delta smelt (Hypomesus transpacificus). The Central Valley Project (CVP) and State Water Project
(SWP) operate under the OCAP and other water rights and water quality requirements (project background provided in Appendix A). These operations comply with the RPAs in the recent BOs for the OCAP from the U.S. Fish and Wildlife Service (FWS 2008) and National Marine Fisheries Service (NMFS 2009). The RPAs include actions to limit reverse flows in Old and Middle Rivers to reduce entrainment of fish at the CVP and SWP export facilities.
The Project seeks to provide equal or improved protection to delta smelt (reduced entrainment at the export pumps) with higher than the minimum allowed water exports described in the OCAP BORPAs while operating within the other water management requirement (D-1641). In particular, the Project is intended to demonstrate that operable barriers, strategically placed in the central Delta and managed in conjunction with some restrictions on OMR negative flows, can provide equal or greater protection for delta smelt than restrictions on OMR negative flows alone. The proposed 2-Gates Project is designed as a demonstration project to test this premise and to improve understanding of the key physical and biological processes needed to restore a sustainable ecosystem.
The 2-Gates Project proposes to install and operate temporary, removable gates in two channels in the central Delta at Old River and Connection Slough (Figure 1). The gates will be used to manipulate flows and key water quality components of delta smelt habitat in order to reduce entrainment of delta smelt at the export facilities.

The Regional Monitoring Program for Water Quality in San Francisco Bay (RMP) is the primary source for long-term contaminant monitoring information for the San Francisco Bay. The RMP is an innovative and collaborative effort among the scientific community, the San Francisco Bay Regional Water Quality Control Board (Water Board), and the regulated discharger community. The Program was initiated by the Water Board as a pilot study in 1989 and has been collecting water, sediment, and bivalve tissue data since its official inception in 1993. Regular monitoring of sport fish tissue and bird eggs for toxic contaminants was incorporated into the Program in 1997 and 2006, respectively.
The Program monitors the different matrices included in “status and trends” monitoring on varying schedules. Additional monitoring occurs as part of short-term “special studies” or pilot studies focused on new regions, matrices, or contaminants of immediate or increasing regulatory interest. In 2015, the RMP collected only water data as part of “status and trends” monitoring. A pilot study was also conducted to collect sediment data from the Bay margins. Bird egg monitoring was originally scheduled to be conducted in 2015, but was delayed until 2016.
The purpose of this report is to document RMP monitoring activities in 2015. The report is organized into chapters on water and sediment. Each chapter contains information on:
• The locations where these samples were collected,
• The field sampling methods,
• The target analytes, laboratories, and analytical methods for each matrix, and
• Any problems encountered or non-conformances to planned procedures.

The Regional Monitoring Program for Water Quality in the San Francisco Estuary (RMP) was created to provide longterm monitoring information on ecosystem health in the Estuary. The impetus for the program development was a resolution by the San Francisco Bay Regional Water Board to require dischargers in the Bay Area regulated under the National Pollution Discharge Elimination System (NPDES) program to participate in regional monitoring. Contribution to the program constitutes compliance with the requirement to participate. Elimination of certain permit requirements for individual permits offset the requirement for continued participation.

In 1992 the San Francisco Bay Regional Water Board passed Resolution No. 92-043 directing the Executive Officer to send a letter to regulated dischargers requiring them to implement a regional multi-media pollutant monitoring program for water quality (RMP) in San Francisco Bay. The Water Board’s regulatory authority to require such a program comes from California Water Code Sections 13267, 13383, 13268 and 13385. The Water Board offered to suspend some effluent and local receiving water monitoring requirements for individual discharges to provide cost savings to implement baseline portions of the RMP, although they recognized that additional resources would be necessary. The Resolution also included a provision that the requirement for a RMP be included in discharger permits. The RMP began in 1993, and over ensuing years has been a successful and effective partnership of regulatory agencies and the regulated community.
The goal of the RMP is to collect data and communicate information about water quality in San Francisco Bay in support of management decisions.

In 2016, bird egg samples were collected from 4 areas for terns with 84 individual samples analyzed for Hg and 12 composites analyzed for Se. Samples for cormorants were collected from 3 areas, with 9 composites analyzed for Hg, Se, PFCs, PCBs, and PBDEs. The sampling and analysis was conducted by the Regional Monitoring Program for Water Quality in San Francisco Bay. The details of the cruise and sample collection methods are described in the RMP Quality Assurance Program Plan, cruise plans, cruise reports, and field sampling reports. These documents are available from the SFEI website (http://www.sfei.org/programs/sf-bay-regional-monitoring-program).

A second year of Sturgeon Derby monitoring will be conducted in collaboration with the 32nd annual Original Sturgeon Derby held by the Foundation Sportsman’s Club out of Bay Point, CA. The sturgeon derby and tissue sampling will occur on February 67, 2016. Tissue samples from female white sturgeon will be collected, and samples from up to fifteen sturgeon will be analyzed.
The Derby offers an opportunity to collect a variety of tissue samples from fish caught for the competition that are otherwise unavailable. This will allow for comparison between selenium concentrations measured in tissues that are easy to obtain nonlethally (muscle plugs, fin rays) and those that are not, but may be of greater interest toxicologically (ovaries, liver) or analyzed for microchemistry (otoliths, for comparison with fin rays). If approved, additional collection of muscle fillet samples will also contribute to a better understanding of the relationship between muscle fillet and muscle plug selenium concentrations. Analysis of tissue samples for stable isotopes will also provide information on diet and habitat use by the sturgeon. Otolith microchemistry will be conducted to support development of a method for fin rays, which can be collected from sturgeon nonlethally during future monitoring efforts.
This study will be performed as a collaboration between SFEI (with RMP funding), USFWS, USGS, UC Davis, and Stantec. The purpose of this Sampling and Analysis Plan is to outline the details for how the samples will be collected, handled, and analyzed by the various parties involved with the study. Additional pathology samples taken by USFWS will not be included in this document, except where needed to inform the collection of other samples.
