Toggle Image SWP Seismic Loading Criteria Report 09/01/2012 (PDF, 11.30 MB)
Description: The State Water Project (SWP) is considered a critical lifeline for California. Earthquakes pose one of the greatest risks to this vital lifeline. Therefore, the selection of seismic loading criteria becomes critical when designing new facilities or evaluating the safety of existing facilities. This report provides design engineers with a guideline in selecting appropriate seismic loading criteria for a wide variety of SWP facilities including dams, canals, pipelines, tunnels, check structures, bridges, buildings, pumping and power plants, and utility overcrossings. The seismic design load shall be selected based on the criticality of a facility and consequences of failure. Most critical facilities are expected to be functional immediately after an earthquake and thereby should experience very limited damage.

Toggle Image IEP - 2008.0717 Response to CALFED ISB report "Moving the IEP into the Future" 07/17/2008 (PDF, 1.53 MB)
Description: This is a response to a April 4, 2008 letter to the Interagency Ecological Program (IEP) Directors regarding the CALFED Independent Science Board's (ISB) recommendations for the Future. Some of the ISB's recommendations are related to activities the IEP already performs, or that it could accomplish through its existing governance structure and funding sources. These include expanding data analysis and publications capabilities; increasing integration and collaboration with other monitoring and research programs within and outside the Delta; strategically analyzing current monitoring efforts, including protocols and locations; and increasing periodic, independent review of program elements and assessing the program's response to those review. Other ISB recommendations are beyond the current IEP scope and the BDCP may be able to help.
Toggle Image IEP - 2008.0404 Moving the Interagency Ecological Program Into the Future, CALFED ISB, April 4, 2008 04/04/2008 (PDF, NA)
Description: As part of its mandate to oversee the quality and use of Science in the Bay-Delta system, the CALFED Independent Science Board (ISB) has been conducting a broad review of the Interagency Ecological Program (IEP). The goal of this effort is to promote innovation in and modernization of the program as well as integration with efforts outside of the Delta. Most importantly, the ISB feels strongly that on-going planning efforts such as Delta Vision and the Bay-Delta Conservation Plan must begin incorporating monitoring and research in general, and the IEP specifically, into their strategic planning. We encourage you, as IEP Directors, to engage with Delta Vision, BDCP and the CALFED Science Program in this regard.
Toggle Image IEP - 2006.0505.2 Science Advisory Group Report on the SAG's 2005-2006 Programmatic Review of IEP's Delta Smelt Program 05/05/2006 (PDF, NA)
Description: This document is comprised of two distinct but interrelated parts: (1) An independent review by the Scientific Advisory Group (SAG) of the Interagency Ecological Program’s delta smelt work that includes the SAG’s recommendations for improving the work and; (2) The IEP’s draft response to the findings and recommendations contained in the SAG Report. The SAG Report appears in its unaltered original font and formatting and the IEP draft responses to each recommendation are shown in bold. Cited references appear at the end of this document. The purpose was to examine current sampling programs and strategies with regard to their utility and value towards understanding what factors influence the health, i.e. the abundance, of delta smelt populations, and hence towards managing water project operations in the Delta that affect Delta Smelt.
Toggle Image IEP - 2006.0505 Delta Smelt Review-Science Advisory Group Report 05/05/2006 (PDF, 78 KB)
Description: On April 13/14, the IEP Science Advisory Group (SAG) met with IEP staff to review the current IEP effort monitoring and studying delta smelt. The purpose of this meeting was to examine current sampling programs and strategies with regard to their utility and value towards understanding what factors influence the health, i.e. the abundance, of delta smelt populations, and hence towards managing water project operations in the Delta that affect delta smelt. This report summarizes the key findings that the SAG believes deserve the most attention by IEP, including: 1. Delta smelt review epitomizes what IEP can and should accomplish.; 2. The power of collaboration; 3. Existing monitoring program needs to be continued with wome critical re-evaluation; 4. Use of data in management actions; 5. It's more of a POD than just a delta smelt issue.

Toggle Image IEP - 2004.1201 Long-term Fish Monitoring Program Element Review 12/01/2004 (PDF, 2.79 MB)
Description: In spring 2004, we initiated a review of the Interagency Ecological Program fish monitoring program elements on behalf of the IEP Management Team. These elements constitute a substantial portion of IEP’s overall monitoring efforts. They represent some of IEP’s longest standing monitoring elements (also referred to as surveys) collecting data used for decades by scientists and resource managers throughout the San Francisco Estuary. As requested, this is a programmatic review to assemble relevant information that can help in the ongoing management and implementation of IEP. In addition, IEP management expects to use this information in decisions about performing more in-depth reviews of program elements and in setting overall program priorities and resource commitments.
Toggle Image IEP - 2003.0807 EMP Response to 2002 IEP SAG Review 08/07/2003 (PDF, 1.53 MB)
Description: The IEP Science Advisory Group (SAG) provided an independent scientific review of the IEP Environmental Monitoring Program (EMP) as part of this program’s 2001-2002 comprehensive programmatic review. Here, the EMP review core team (including Wim Kimmerer) provides a written response to the SAG review dated May 22, 2002. The core team is particularly thankful for SAG comments regarding the basis for the EMP. These comments led to an intense and productive exploration of program aims and the conceptual basis for the EMP sampling design, yielding a much improved basis for the program and sampling design. As its “primary recommendation,” the SAG called for the EMP to focus on rapidly turning data into useful products by increasing the program’s "human intellectual investment" and working with outside researchers.
Toggle Image IEP - 2002.0522 Science Advisory Group May 22, 2002 Review of Environmental Monitoring Program 05/22/2002 (PDF, 204 KB)
Description: A core element of the Interagency Ecological Program (IEP) is the Environmental Monitoring Program (EMP), mandated by the State Water Resources Control Board to document the changing status of water quality and biological communities in the Sacramento-San Joaquin River Delta and downstream embayments of San Francisco Bay. Sustained, uninterrupted operation of the EMP for over 30 years is a remarkable achievement that in many ways serves as a model of successful state-federal partnership in environmental monitoring, providing one of the longest and most valuable records of combined water quality-biological monitoring in the U.S. Members of the IEP Science Advisory Group (SAG), including outside specialists recruited for the EMP technical review, unanimously endorsed the Environmental Monitoring Program.
Toggle Image Water Quality Conditions in the Sacramento-San Joaquin Delta During 1996 07/31/2001 (PDF, 5.88 MB)
Description: Water year 1996 was classified as a wet year with an average stream flow similar or somewhat above that in 1993. As in many recent years, snow pack water content was below average and precipitation was high early in the spring. Dilution associated with the high stream flow produced low nutrient and specific conductance, and high dissolved oxygen concentrations compared with drier years - especially the recent drought years 1987-1992. However, the pattern of highest nutrient concentration in the winter among seasons and in the south delta among regions persisted. Water quality conditions in 1996 were also characterized by comparatively higher Secchi disk depth than in the early 1970's. Further, even though 1996 was a wet year, the dissolved oxygen concentration in the Stockton Ship Channel was below the USEPA and RWQCB standards.

Toggle Image Review of the Bay Program by the Science Advisory Group 10/01/1999 (PDF, 49 KB)
Description: The SAG had several comments and recommendations for the IEP, with regard to the Bay Program: I. Fisheries and macroinvertegrate monitoring is extremely important and should be continued; II. Both people and funding resources have been diverted from the Bay program by competing demands for DFG expertise. This diversion of resources has been to the detriment of the program. A renewed commitment to the program is needed. III. The SAG identified 4 goals that have guided the program. These goals should be consulted frequently to make sure that the program is on focus. IV Data collection and enumeration of fishes has dominated the first 20 years of the program and this monitoring must continue, but the program must also evolve with increased resources for analysis and synthesis to explain the mechanisms behind the patterns observed.

In addition, this report documents and presents the findings from previous aquifer testing and well development with the lower-confined Tuscan Formation aquifer. The investigation was undertaken as a part of the Groundwater Development effort of the State Water Project Future Supply Program.
Toggle Image Problems of the Lower San Joaquin River Influencing the 1963 Salmon Run 01/15/1964 (PDF, 2.45 MB)
Description: Studies conducted by the Delta Fish and Wildlife Protection Study defined a problem relating to the upstream migration of adult salmon caused by flow reversal and pollution in the lower San Joaquin River area. Further studies are underway to solve this problem in the future. These studies indicated that during 1961 and 1962 flow reversal and pollution from cannery waste discharges did exist in the San Joaquin River during the September-October period when adult salmon are normally migrating. The salmon runs in all of the tributaries of the San Joaquin River were drastically reduced for each of these two years, decreasing from approximately 50,000 fish to under 3,000. Water development projects, which are perhaps the principal reasons for past declines, may well become the means for restoration of the salmon.
