IEP - 1993.0801 A Review of the Interagency Ecological Study Program and Recommendations for its revision 08/01/1993 (PDF, NA)Description: The Interagency Ecological Study Program was initiated in July 1970 by a Memorandum of Agreement (MOA) between four state and federal agencies (California Department of Fish and Game, California Department of Water Resources, U.S. Bureau of Reclamation, and the U.s. Bureau of Sport Fisheries and Wildlife). This MOA was an outgrowth of testimony at Water Rights Hearing 1379, which indicated that construction and operation of the State Water Project and Federal Central Valley Project may have been contributing to fish and wildlife problems in the estuary. This 1993 report describes the findings and recommendations of an ad hoc Review Team commissioned by the IESP Coordinators.
IEP - 1995.0728 Science Advisory Group Long Term Monitoring Review July 28, 1995 07/28/1995 (PDF, 24 KB)Description: The Science Advisory Group is unanimous in its support for the long term monitoring components of the IEP. Monitoring activities, beginning in the 1960's have produced an invaluable set of observations to document changes in water quality, habitats, and populations of valued species. Although many complex problems remain unresolved, the Bay-Delta ecosystem is one of the best understood and most comprehensively studied estuarine ecosystems in the U.S. as a result of IEP. IEP data are the basis for the public's growing concern for the health of the Bay-Delta and its living resources; it has been critical in detecting the arrival of exotic species and in understanding their ecosystem-level effects; and it is the basis for environmental standards to protect this unique ecosystem.The IEP has made clear efforts in recent years to adapt.
IEP - 1999 Report of the 1980-1995 Fish, Shrimp, and Crab Sampling in the San Francisco Estuary, California 11/01/1999Description: Before 1980, little scientific information was available to set water quality standards for the protection of the fish and invertebrates of San Francisco and San Pablo bays. In 1979, the Interagency Ecological Program (IEP) designed a plan to collect biological and physical data from South San Francisco Bay to the west delta. The State Water Resources Control Board (SWCRB) approved this plan and the Bay-Delta Division of the California Department of Fish and Game (CDFG), operating as part of the IEP, set the plan in action. The objective of the study was to determine the effects of freshwater outflow from the delta on the abundance and distribution of marine and estuarine fishes, shrimps, and crabs and use this knowledge to understand the volume and timing of freshwater outflow that is necessary for their well-being.
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.
IEP - 2003.0325 Environmental Monitoring Program Review and Recommendations Final Report, March 25, 2003 03/25/2003 (PDF, 1.25 MB)Description: The intent of this review was to determine how the EMP could better meet current information needs for water resource mangement and protection. This review also reexamined program aims and the relationship of the EMP to other compliance and baseline aquatic monitoring activities in the Bay-Delta. This programmatic review was conducted in 2 phases. The first phase was an in-depth technical review of the EMP. The second phase was a review by program managers and legal staff from various IEP agencies. Overall, the EMP was found to be a tremendously valuable long-term environmental monitoring program providing essential data and information for resource management and scientific understanding of estuarine processes... the EMP's greatest asset is it's consistent and comprehensive long-term environmental data record, but needs improvement.
IEP - 2003.0325.2001-2002 Review of the Environmental Monitoring Program (EMP) for SWRCB in compliance with Water Right Decision 1641, Condition 11 03/25/2003 (PDF, 539 KB)Description: DWR/USBR fund and maintain, in cooperation with the Califorinia Department of Fish and Game (DFG) and the US Geological Survey (USGS), a water quality compliance and baseline monitoring program referred to as the "Environmental Monitoring Program" (or EMP) for the Bay-Delta. D-1641 specifies three goals for this monitoring program: (1) to ensure compliance with the Bay-Delta water quality objectives; (2) to identify meaningful changes in any significant water quality parameters potentially related to operation of the State Water Project (SWP) or the Central Valley Project (CVP); and (3) to reveal trends in ecological changes potentially related to SWP/CVP operations. Condition 11 (e) requires DWR/USBR to evaluate the EMP and report their conclusions to the Executive Director of the State Water Resources Control Board every three years.
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.
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.
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.

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.
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.
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.
