NOAA Fisheries Northwest Region supports efforts to restore the ecological function of our region’s habitat. Restoring habitat contributes to the recovery of species currently protected under the Endangered Species Act (ESA), ensures that critical habitat designated under the ESA will serve its intended conservation role, and advances the conservation and enhancement of essential fish habitat (EFH) designated under the Magnuson-Stevens Fishery Conservation and Management Act (MSA).

Subsidized or subsidizing? Municipal drinking water service funds in California

Utilities Policy (Elsevier) | September 29th, 2022

In the longstanding debate over efficiency and effectiveness in drinking water provision between public versus privately governed systems, one of the main contention points is the reasons for different bill levels imposed by city-run as compared to privately owned water systems. In this study, we examine one potential explanation for disparities in bills: whether cities use their general funds to subsidize their drinking water fund operations or vice versa. Either practice goes against “user pays” principles, as pointed out by critics of municipal operation. However, the claims have not been tested empirically at scale. We extract and analyze city water enterprise fund financial data from the California State Controller Cities Raw Data of Financial Transaction Reports to empirically assess the extent to which and reasons why interfund transfers occur in California's 267 municipally owned water utilities. We find very little evidence that substantial interfund transfers, in either direction, occur between water enterprise funds and general funds within California cities, indicating that enterprise fund control measures are generally successful. These findings suggest that with proper regulation, the municipal fund subsidy debate is essentially a distraction from the real reasons why municipal and other water provider rates differ substantially.

Sustainability Outlook Indicator Descriptions and Methodology

The Sustainability Outlook describes how, through the lens of four societal values — public health and safety, healthy economy, ecosystem vitality, and opportunities for enriching experiences — it will help identify desired water management outcomes and indicators. Those outcomes and indicators can be used to gauge the status of, and progress toward, sustainability. Because sustainability is not something achieved once and forever, the Sustainability Outlook and the representative indicators are intended to be adaptive and help water resource managers address changing circumstances and incorporate lessons learned.  This document details the process to date for developing the sustainability indicators and includes descriptions of the initial indicators. Indicators are presented according to societal value, corresponding intended outcome, and classification (“Basic” with potential statewide application or “Watershed” level application, “Advanced” for future development, or “Archived” with no additional development identified at this time). Each intended outcome has several indicators, and in some cases, indicators may apply to multiple outcomes.  This version of the document (December 2018) is being released concurrently with the public review draft of Update 2018. It is considered an in-progress review draft because indicator assessments are ongoing, and the contents are subject to change as indicators are more fully developed, combined, or otherwise modified. As part of Update 2018, future versions of this paper will reflect the status of indicator development and stakeholder input. 

Sustainable Development and Environmental Justice

This chapter addresses the incorporation of environmental justice into the general plan. While environmental justice is not a mandatory topic in the general plan, there is a strong case for its inclusion. Federal and state anti-discrimination statutes, which have a long history, apply to planning as they do to other policy areas. As discussed below, environmental justice issues are often related to failures in land use planning. Planning policies that promote livable communities and smart growth can be tools for achieving environmental justice. In keeping with that idea, this chapter begins with a discussion of sustainable development. Sustainable development provides a context for understanding how environmental justice fits into land use planning. This chapter concludes with a discussion of transit-oriented development, which has important implications for environmental justice and sustainable development.

The Sustainable LA Grand Challenge (SLA GC) Environmental Report Card (ERC) for Los Angeles County (L.A. County) is the only comprehensive environmental report card for a megacity in the world. This 2019 ERC on Water provides an in-depth look at the region’s efforts in moving toward a more resilient local water supply, which requires maximizing high quality local water supplies, improving water conveyance and treatment infrastructure, reducing water consumption, and implementing innovative technology and policy solutions. Twenty indicators were assessed across eight categories. Many of these indicators are new areas of assessment for the ERC and will provide a more comprehensive picture of current conditions compared to the 2015 ERC that last assessed L.A. County’s water. Grades were assigned in each category based on compliance with environmental laws or numeric standards where applicable, on our best professional judgment, and on historical improvements and context. This year’s grades range from D/ Incomplete to B+, and although there has been great progress in some areas, others still require significant improvement to raise the county’s C+ average.

Sustainable Management of a Water Reservoir System Facing Climate Uncertainty

Water scarcity is a growing global issue. It affects even highly developed regions like California, the world's fifth largest economy, where years of severe droughts interspersed with unusually wet seasons have caused societal debates over the management of the water resources stored in the state's extensive reservoir system. This paper presents a strategic optimization model for the long-term, sustainable management of such a system. Introducing a new modeling paradigm based on cycles of stochastic length, defined by the event when all reservoirs are simultaneously full, we avoid the limitations of traditional models and obtain sustainable management policies. To address the unpredictable effect of climate change on future water supply, we adopt a distributionally robust framework where nature chooses adverse inflow distributions. This leads to a stochastic shortest path problem under distributional ambiguity. Using tools from stochastic dynamic programming and aggregation methods, we obtain policy insights and overcome the curse of dimensionality typically associated with systems models. In a case study for California's Sacramento River Basin, we report suboptimality gaps between 3% and 15%, with our sustainable management policy reducing average cycle shortage costs by 40% compared to the current policy, demonstrating the significant cost saving potential.

Sustainable Water and Environmental Management in the California Bay-Delta

National Academy of Sciences (NAS) | March 29th, 2012

Water management in the California Bay Delta is directed toward providing a more reliable water supply for California, and protecting and rehabilitating the Delta ecosystem, including five endangered and threatened populations and species of fish that live in or migrate through the Delta. However, water management in the Bay and Delta is distributed among many agencies and organizations, a structure that hinders the development and implementation of an integrated, comprehensive plan. As a result, recent Bay Delta planning efforts have not resolved the best plan for the environment or for satisfying anticipated water needs. Challenges include the fact that water scarcity has not been adequately addressed in planning for Delta water and environmental management; the interacting effects of the many environmental stressors that impact the Delta ecosystem, and the many biological and physical effects of climate change. This report discusses the issue of scarcity, factors affecting the listed species and the Delta ecosystem in general, future water-supply and delivery options, scientific uncertainties, the degree of restoration likely to be attainable, and the need for comprehensive planning. Key Messages Planning efforts to implement the two goals of providing a more reliable water supply for California and protecting and rehabilitating the Delta ecosystem have not led to clarity on how the inevitable tradeoffs between the two goals should be managed, particularly when water is in short supply. Climate change is one of most challenging and important issues confronting the management and rehabilitation of the Delta ecosystem. Changes in climate are expected to have profound effects on the physical and ecological structure and functioning of the Delta, as well as on the availability of water in California. Many environmental stressors, including water diversions, contaminants in the water, and introduced species affect the structure and functioning of Delta ecosystems. Interactions among stressors and between stressors and ecosystem processes are widespread and complex. Furthermore, species differ in their responses to stress. This complicates the interpretation and evaluation of the effects of stressors on the ecosystem, and makes it impossible to identify which stressor is the root cause of a certain environmental problem, or even to rank the stressors with any certainty. The large number of stressors, their effects and interactions lead to the conclusion that efforts to eliminate any one stressor are unlikely to reverse declines in listed species. Opportunities exist to mitigate or reverse the effects of many stressors. Continued effects analyses, modeling, and monitoring are necessary to ensure actions taken to rehabilitate the ecosystem are cost-effective. Due to the extensive physical changes that have already taken place and are still occurring in the Delta ecosystem and its tributary watersheds, it will not be possible to restore the habitat to its pre-disturbance state. Delta restoration programs will need to balance consideration of an ecosystem approach with the Endangered Species Act's emphasis on individual species. Assessments suggest that many species will be affected by shifts changes in the pattern and type of precipitation due to climate change. Projected increases in mean sea level and extremes of precipitation have the potential to increase the frequency of levee failures and the inundation of islands, in part because the levees continue to subside due to the oxidation of peat. Sea level rise also has the potential to enhance salt water intrusion and alter water quality. Planning and evaluation of future environmental and economic scenarios will need to address uncertainties in projections, integrated analysis, and the development of risk management strategies. Future planning should also include a climate-change based risk model and analysis that incorporates data on the actual changes in Delta conditions as well as alternative future climate change scenarios and their probability. The instability of levees and the fact that the failure of one levee can affect others are likely to be major issues for achieving any measure of water-supply reliability or ecosystem rehabilitation. Continuing the status quo of improving levees will not always be the most environmentally sustainable or economically defensible response in the years ahead. Science is necessary to inform actions and proposals, but does not provide the entire, prioritized, integrated analysis needed. Societal and political considerations are also important factors in determining the most appropriate policy. Undertaking a comprehensive review of water planning and management functioning would allow California to anticipate future needs such as water scarcity, balanced consideration of all statewide water use practices, and water engineering alternatives. As a result, the Delta would be an effective partner in statewide water management plans. It is likely that the scarcity of water for all needs in the Delta will become severe. While more effective planning is developed, the state will need to use its water resources efficiently and productively. The committee has not analyzed the benefits and disadvantages of an isolated conveyance facility, because not enough specific information was available about it, and therefore there is no recommendation with respect to its adoption as a major part of water management in the Delta. However, the considerations such as the form such a facility would take, its size, location, and the diversion design and operation, including the role of current diversions, should be analyzed as part of any integrated Delta plan, and compared to alternative water management options, including current operations.

Sutter County Groundwater Management Plan

Sutter County intends this GMP to be relevant for the entire County. Sutter County overlies the south central part of the Sacramento Valley Groundwater Basin, and specifically the Sutter Subbasin and portions of the East Butte and North American Subbasins. The majority of the County is serviced by water and irrigation districts, reclamation districts, cities, and public utility districts, which have the authority to manage groundwater in their service areas. Unless those entities decline to manage groundwater on their own, and instead enter into agreements with the County, this GMP does not formally apply to those areas. If those entities choose not to adopt their own GMPs, they have the option of taking formal action to adopt the Sutter County GMP for their areas. By doing so, they will fulfill the requirements of the groundwater management provisions of the California Water Code.
