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.

Metropolitan’s 2015 Urban Water Management Plan (UWMP) has been prepared in compliance with Water Code Section 10608.36 of SB X7-7, which was enacted in 2009, and Sections 10610 through 10656 of the Urban Water Management Planning Act (Act), which were added by Statute 1983, Chapter 1009, and became effective on January 1, 1984. This Act requires that every urban water supplier providing water for municipal purposes to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually prepare and adopt, in accordance with prescribed requirements, an urban water management plan.
The Act requires urban water suppliers to describe and evaluate sources of water supply, efficient uses of water, demand management measures, implementation strategy and schedule, and other relevant information and programs. Urban water suppliers are required by the Act to update their UWMP and submit a complete plan to the California Department of Water Resources (DWR) every five years. An UWMP is required in order for a water supplier to be eligible for DWR administered state grants and loans and drought assistance.
As with Metropolitan’s previous plans, the 2015 UWMP does not explicitly discuss specific activities undertaken by its member agencies unless they relate to one of Metropolitan’s water demand or supply management programs. Presumably, each member agency will discuss these activities in its UWMP.
The information included in the 2015 UWMP represents the most current and available planning projections of supply capability and demand developed through a collaborative process with the member agencies. Metropolitan’s Board recently adopted the 2015 Integrated Water Resources Plan, Water Tomorrow (2015 IRP Update), which represents Metropolitan’s comprehensive planning process and will serve as Metropolitan’s blueprint for long-term water reliability, including key supply development and water use efficiency goals.

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 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.

Billions of dollars are at stake in the decisions that society makes regarding activities that are directly intended to protect Bay water quality. The region has made huge investments to build and operate the infrastructure to collect and treat the region’s municipal and industrial wastewater, and continued investment at a similar scale will be needed to maintain, upgrade, and operate this infrastructure to serve a growing Bay Area population. The region has spent and will spend comparably large sums to manage stormwater and establish green infrastructure in our cities to minimize the adverse water quality impacts of stormwater on the Bay. Large investments have been and will be made to manage contaminated sediment in the Bay, both at sites identified for cleanup and for dredging to maintain channels for commercial and recreational vessels.
Billions more are at stake in decisions regarding activities that influence Bay water quality as unintentional side-effects. Commercial product formulation and usage (including pesticides, pharmaceuticals, personal care products, electrical equipment, home furnishings, automobile components, and many, many others), sediment management, water supply management, energy production, and habitat restoration and management are all immense and essential enterprises that have a tremendous influence on Bay water quality.
