California Aqueduct Subsidence Study

In 2006, the San Luis Field Division of the California Department of Water Resources' Division of Operations and Maintenance (O&M) began to see a reduction in flow capacity through the California Aqueduct (Aqueduct) Pools 20 and 21. Subsidence had lowered portions of the Aqueduct and caused the concrete liner freeboard (the vertical distance between the water surface and the top of the concrete liner) to be reduced from its normal of 3 feet, to less than 1 foot. Subsidence had also decreased the ability to store water in those pools, which is normally done to add operational flexibility and to manage pumping at the Aqueduct’s pumping plants. While subsidence has reduced the amount of freeboard and flow capacity at specific locations, contracted deliveries have not been curtailed through 2016. Additional work, to be addressed in the next phase of the project, will quantify how hydraulic limitations have impacted operations and will estimate future impacts to deliveries, based on forecasted subsidence rates. The purpose of this project is to research and study past and present subsidence reports and data, and to understand and summarize the magnitude, location, and effects on the Aqueduct. This report summarizes the significant information found, and presents the results of the data that were analyzed.

California State Water Project 2006 Watershed Sanitary Survey Update

California Department of Water Resources (DWR) | June 20th, 2007

The State Water Project (SWP) provides drinking water to approximately two-thirds of California’s population and is the nation’s largest state-built water development

The State Water Project (SWP) provides drinking water to approximately two-thirds of California’s population and is the nation’s largest state-built water development project. The SWP extends from the mountains of Plumas County in the Feather River watershed to Lake Perris in Riverside County. It is linked with the Central Valley Project (CVP) that extends from southern Oregon in the Sacramento River watershed to the Mendota Pool. The watershed of the SWP is vast; encompassing the 27,000-square-mile Sacramento River and 13,000-square-mile San Joaquin River watersheds and at times, the 13,000-square-mile Tulare Basin watershed. The contaminant sources in the SWP watersheds have been well documented in the three previous sanitary surveys. The California Department of Health Services (CDHS) requested that the 2006 Update address the Jones Tract levee failure and emergency response procedures, efforts to coordinate pathogen monitoring in response to the Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR), and a review of significant changes to the watersheds and their impacts on water quality.   A Technical Review Committee (TRC) was formed to guide development of the scope of work and provide technical expertise and review of the draft report. In addition to addressing the issues raised by CDHS, the TRC determined that the 2006 Update should focus on evaluating the sources of the water quality problems that the SWP Contractors face and recommending actions that the SWP Contractors can take that will lead to improvements in water quality over the next five years.

California Subsidence Program - Subsidence and Groundwater Monitoring Project

This Initial Study (IS) and Mitigated Negative Declaration (MND) has been prepared by the California Department of Water Resources (DWR) to address the environmental impacts of the proposed California Aqueduct Subsidence Program (CASP) Subsidence and Groundwater Monitoring Project (proposed project) and to satisfy the requirements of the California Environmental Quality Act (CEQA). The DWR is planning installation of equipment to collect spatial information at approximately five (5) groundwater and subsidence monitoring stations along the California Aqueduct (Aqueduct) (approximately Mile Posts 213.0L, 230.6L, 259.6L, 271.2L, and 279.1L within the San Joaquin Field Division) (Figure 1). The proposed project would provide real-time data to monitor groundwater levels and other spatial information as they relate to ground subsidence. The data would be used to help inform how subsidence is affecting the Aqueduct and would assist in maintaining infrastructure of the State Water Project (SWP). The proposed project is described in more detail in Chapter 2.

CalSim II Simulation of Historical SWP-CVP Operations Technical Memorandum Report

CalSim is a generalized water resources planning tool developed jointly by the Department of Water Resources (DWR) and the US Bureau of Reclamation Mid-Pacific Region (Reclamation). CalSim II is the application of the CalSim software to model the State Water Project (SWP), the federal Central Valley Project (CVP) and areas tributary to the Sacramento-San Joaquin Delta (Delta). The primary purpose of the CalSim II model is to evaluate the water supply reliability of the CVP and SWP, 1) at current or future levels of development, 2) with and without various assumed future facilities and, 3) with different modes of facilities operations. The purpose of the Historical Operations Study is to evaluate the ability of CalSim-II to represent CVP and SWP operations, in general, and the delivery capability of the projects, in particular, through the monthly simulation of recent historical conditions. The Historical Operations Study is part of a larger CalSim II evaluation process. Other components of the evaluation include a survey of the water community to gather their views and opinions of the model, a model peer review by leading academics and practitioners, and a sensitivity analysis on model inputs. It is hoped that this effort, to assess the quality and limitations of CalSim II, will lead to a wider debate about critical model issues, help direct model development in both the near and long term, and eventually lead to greater public confidence and acceptance of the model.
