IEP Technical Reports focus on scientific topics for resource managers, scientists and the public. An IEP Technical Report is an irregularly produced publication series that provides an avenue for reporting on larger, more complex studies or data collection effort. IEP Technical Reports are usually greater than 70 type written pages and do not undergo external peer review. Findings should be interpreted with caution.
Recent Technical Reports
Ecological Impacts of Drought on the Sacramento-San Joaquin Delta with special attention to the extreme drought of 2020-2022
Drought Synthesis Team. 2023. Ecological Impacts of Drought on the Sacramento-San Joaquin Delta. Interagency Ecological Program for the San Francisco Estuary. IEP Technical Report 100.
- In this report (PDF) the authors integrated long-term data from the Interagency Ecological Program's long-term monitoring, as we as other data sources, where available, to assess the impacts of droughts on the upper San Francisco Estuary (Suisun Bay, Suisun Marsh, and the Delta). The report describes certain key changes that occur during droughts.
Synthesis of data and studies related to the effect of climate change on the ecosystems and biota of the Upper San Francisco Estuary Year 2022
Climate Change MAST (Climate Change - Management, Analysis and Synthesis Team). 2022. Synthesis of data and studies related to the effect of climate change on the ecosystems and biota of the Upper San Francisco Estuary. IEP Technical Report 99.
- An important climate change review has been published as an IEP Technical Report. This recent effort (PDF) effort by the Climate Change Management Analysis and Synthesis Team (MAST) represents critical analysis of issues important for continued management of water and aquatic habitats in the upper San Francisco Estuary and surrounding watersheds.
White papers providing a synthesis of knowledge relating to Delta Smelt biology in the San Francisco Estuary, emphasizing effects of flow
FLOAT-MAST (Flow Alteration - Management Analysis and Synthesis Team), 2022. White papers providing a synthesis of knowledge relating to Delta Smelt biology in the San Francisco Estuary, emphasizing effects of flow. Interagency Ecological Program, Sacramento, CA. IEP Technical Report #98. 191 pp.
- Prepared by the Flow Alteration (FLOAT) Management Analysis and Synthesis Team (MAST), these white papers (PDF) are part of developing an annual summary and synthesis of factors affecting the Delta Smelt population. They provide the necessary background for understanding the annual summary and synthesis (in development) and will be useful to any one needing a basic background in Delta Smelt ecology.
- These white papers are also are intended to be living documents updated at intervals to remain current with recent advances in understanding of the Delta Smelt population.
