Budget Request Summary The Department of Water Resources (DWR)requests authority for a total of 150 permanent full-time positions funded by the State Water Project (SWP) to be phased in over four years as follows: 67 positions in 2021-22; 35 positions in 2022-23; 32 positions in 2023-24; and 16 positions in 2024-25; to address the following State Water Project initiatives: On-Going Maintenance, Asset Management/Maintenance Management and Affordability, Engineering & Technical, California Aqueduct Subsidence and Emergency Action Planning , emergency preparedness, and physical security enhancements. This request addresses specific DWR actions included in the Governor’s Water Resilience Portfolio, which prioritizes the rehabilitation of infrastructure damaged by subsidence and the implementation of risk-informed asset management plans for critical SWP infrastructure: • Proposal 19.3 (subsidence rehabilitation of critical infrastructure) and • Proposal 19.5 (risk-informed asset management plans for critical SWP infrastructure). These new actions require dedicated staff to perform new functions in addition to existing SWP program activities. The proposed positions will provide DWR with the resources and means to: Increase maintenance, refurbishment, repair, and replacement of aging infrastructure which is required to continue to meet the demands of the SWP and support the increased flexibility being requested to support water resiliency. Continue to develop and implement DWR’s Asset Management Program which optimizes, prioritizes and financially plans for projects to address aging infrastructure based on risk; enhance condition assessment and maintenance programs, and facilitate increased design, construction and inspection projects for an aging infrastructure. Perform studies, expand existing maintenance and facility inspections, execute preventative design and construction efforts, develop new or update existing guidelines and standards, adopt new technologies and system enhancements, Continue to address the adverse effects of subsidence along the SWP by implementing design, environmental permitting, and construction activities that will optimize resiliency and improve operational flexibility of the SWP as well as support safe and reliable delivery of water. Implement new Dam Safety Emergency Action Planning (EAP), emergency preparedness, and physical security enhancements. To respond timely, safely, and cost effectively to urgent or emergency work as defined by Public Contract Code §10122 et. seq. and other Executive, Legislative, or Regulatory mandates. B. Background/History Managed by DWR, the SWP is the largest state-built, multi-purpose water project in the United States, and one of the largest in the world. SWP funding was authorized by the California Legislature in 1959 and approved by voters in 1960 through the Burns-Porter Act. The Burns-Porter Act expressly authorized the State of California to enter into contracts for the sale, delivery, or use of the water made available by the State Water Resources Development System (California Water Code [CWC] 12937(b)). In return for the state financing, constructing, operating, and maintaining the facilities needed to provide water service, the 29 public water agencies contractually agreed to pay all associated SWP capital and operating costs including the 1.75 billion in bonds used to construct the SWP facilities. The resources in this request will be funded pursuant to CWC 12937 (b). DWR is an integral part of that growth through water delivery, pumping and hydroelectric plants operation, water movement and storage, and operation of dams up and down California. 1 California communities developed near SWP infrastructure due to the flood protection and water security the infrastructure provides. The infrastructure requires continuous maintenance, refurbishment and upgrades to meet the growing demands for water supply, clean energy, and flood protection under increased pressures of climate change. The SWP provides a supplemental water supply to approximately 27 million Californians and 750,000 acres of irrigated farmland. Seventy percent of SWP water goes to urban users and thirty percent to agriculture. The system conveys an annual average of 2.6 million acre-feet of water to 29 public agencies that purchase SWP water for distribution within their respective areas. The system’s facilities include 35 storage facilities, reservoirs and lakes; 21 pumping plants; 4 pumping- generating plants; 5 hydroelectric power plants; and more than 700 miles aqueducts, canals, tunnels, and pipelines, the highest pumping lift in the United States, Edmonston Pumping Plant, and the tallest dam in the nation, Oroville Dam. The system also provides flood control, hydroelectric power generation, recreational opportunities and ecosystem enhancements. Along the San Luis Field Division and San Joaquin Field Division, portions of the aqueduct were built to control subsidence. Canal embankments and structures were originally built higher to accommodate future subsidence. However, some canal embankments had to be raised in the 80’s and 90’s. During the 2014 to 2017 drought there was a vertical change of 2.75 feet and at least a 20 percent conveyance capacity reduction. As subsidence settlement continues, there will be a significant reduction of flow capacity (cfs), loss of operational flexibility, increased costs to deliver water, more Aqueduct failures, and reduced ability to utilize renewable energy sources. As part of the California Aqueduct Subsidence program, efforts have been taken to identify where subsidence is impacting the SWP, how much it is impacting water deliveries and what the near- and long-term solutions are. This includes evaluating 50 years of precise surveys and working with National Aeronautics and Space Administration (NASA) to monitor and assess rates of subsidence using satellite mapping; conducting research and hydraulic modeling and assessing impacts to SWP structures and operations; and identifying, evaluating and selecting remediation alternatives as well as evaluating potential areas of future subsidence. The failure of the Oroville Dam Flood Control Spillway in February 2017 highlighted the importance of committing sufficient resources to inspect, assess conditions, set priorities, meet regulatory compliance obligations, and maintain the SWP including its regulated dams and approximately 700 miles of aqueducts, canals, tunnels and pipelines. Of the 26 regulated dams, 22 are under the jurisdiction of the State Division of Safety of Dams (DSOD), with 11 of those also under the jurisdiction of the Federal Energy Regulatory Commission (FERC). The remaining four dams are part of the state/federal San Luis Joint Use Facilities and are owned by the United States Bureau of Reclamation (Reclamation). In compliance with DSOD and FERC regulations, DWR’s Operations and Maintenance (O&M) Dam Safety Services (DSS) convenes an independent consulting board (Board), on 5 -year cycles to review dam performance data and operation and maintenance records, participate in comprehensive inspections, and produce a report of categorized findings and recommendations. The recommendations typically require follow-up actions that are undertaken and managed by DSS. FERC and DSOD also participate in the conduct of these Boards. Subsequent to each Board meeting, DSS develops the scope of work, schedule, budget, and resources needed to address each of the findings and recommendations. Each scope of work can range in complexity from minor assessments to major dam alterations. Major alterations could include seismic remediation of dam foundations,

    3.12 Hydrology and Water Quality

    3.12 HYDROLOGY AND WATER QUALITY EXECUTIVE SUMMARY This section describes the drainage features, stormwater quality, flooding hazards, and flood-protection improvements within the City’s Planning Area. Regulatory agencies governing stormwater quality and flooding hazards are also discussed. The City’s Planning Area is comprised of the City’s boundaries and adopted Sphere of Influence (SOI). The County’s Planning Area consists of unincorporated land within the One Valley One Vision (OVOV) Planning Area boundaries that is outside the City’s boundaries and adopted SOI. Together the City and County Planning Areas comprise the OVOV Planning Area. With implementation of the proposed General Plan goals, objectives, and policies potential impacts on hydrology and water quality would be less than significant. EXISTING CONDITIONS Surface Water Drainage Patterns within City’s Planning Area Surface water drainage patterns are dependent on topography, the amount and location of impervious surfaces, and the type of flood control that is located in an area. The size, or magnitude, of a flood is described by a term called a “recurrence interval.” By studying a long period of flow record for a stream, hydrologists estimate the size of a flood that would have a likelihood of occurring during various intervals. For example, a five-year flood event would occur, on the average, once every five years (and would have a 20 percent chance of occurring in any one year). Although a 100-year flood event is expected to happen only once in a century, there is a 1 percent chance that a flood of that size could happen during any year.

    Energy and Water Co-Benefits from Covering Canals with Solar Panels B

    Nature Sustainability, 2021 https://doi.org/10.1038/s41893-021-00693-8 Author-formatted copy Energy and water co-benefits from covering canals with solar panels B. McKuina,b*, A. Zumkehra, J. Taa, R. Balesa, J. H. Viersa, T. Pathaka, J. E. Campbell b* a Sierra Nevada Research Institute, University of California, Merced b Environmental Studies Department, University of California, Santa Cruz * Corresponding authors: [email protected] and [email protected] Solar-power development over canals is an emerging response to the energy-water-food nexus that can result in multiple benefits for water and energy infrastructure. Case studies of over-canal solar photovoltaic (PV) arrays have demonstrated enhanced PV performance due to the cooler microclimate next to the canal. Further, shade from the PV panels has been shown to mitigate evaporation and could mitigate aquatic weed growth. However, the evaporation savings and financial co-benefits have not been quantified across major canal systems. Here we use regional hydrologic and techno-economic simulations of solar PV panels covering California’s 6350 km canal network, which is the world’s largest conveyance system and covers a wide range of climates, insolation rates, and water costs. We find that over-canal solar could reduce annual evaporation by an average of 39 ± 12 thousand m3 per kilometer of canals. Furthermore, the financial benefits from shading the canals outweigh the added costs of cable-support structures required to span canals. The net present value (NPV) of over-canal solar exceeds conventional over-ground solar by 20% to 50%, challenging the convention of leaving canals uncovered and calling into question our understanding of the most economic locations to locate solar power.

  • Where Does Our Water Come From?

    Where Does Our Water Come From?

    Have you ever wondered where your water comes from? Here in Huntington Beach, about three-quarters of our water is drawn from local groundwater supplies, while the rest is imported from both Northern California and the Colorado River. Shasta Trinity Lake Water from Northern California travels to us through a complex delivery system Lake known as the California State Water Project. Designed and built in the 1960s, the State Water Project is one of the largest public water and power utilities in the REDDING world, providing drinking water for more than 25 million people statewide. THE Managed by the California Department of Water Resources, the project stretches CALIFORNIA AQUEDUCT over 700 miles, from Lake Oroville in the north to Lake Perris in the south. Water Lake stored in Lake Oroville, Folsom Lake, and other tributaries, and fed by snow melt Oroville from the Sierra Mountains, flows into the Sacramento and San Joaquin rivers, and from there into reservoirs in the Bay-Delta region. Feather River Sacramento From the Bay-Delta, giant pumps lift the water into the 444-mile-long California River Aqueduct, there to flow southward to cities and farms in central and Southern Folsom SACRAMENTO Lake California. Composed mainly of concrete-lined canals, the Aqueduct also includes over 20 miles of tunnels, more than 130 miles of pipelines, New Hogan and 27 miles of siphons. Along the way, the water is pumped Reservoir Managed by the Metropolitan The 2,882 feet over the Tehachapi Mountains. The Edmonston Water District of Southern Bay-Delta Pumping Plant alone lifts millions of gallons a day up California, the Colorado River SAN San 1,926 feet, the highest single water lift in the world.
