PPIC Report: Making the most of water for the environment: a functional flows approach for California’s rivers

In California, water and land management activities have substantially altered river flows and degraded river channels and their floodplains. The result has been a precipitous decline in native fish populations, including the collapse of valued salmon fisheries, and widespread imperilment of freshwater biodiversity. Environmental flows—flows in rivers and streams necessary to sustain ecosystem health—are essential to reversing these trends. Yet many rivers in California lack environmental flows. And for those rivers with such protections, environmental flows are typically established at static minimum levels, which fail to preserve the natural seasonal and interannual variability of flow that sustains healthy ecosystems. A new approach to managing environmental water is needed.  Building on previous PPIC work in this area, we recommend a “functional flows” approach for managing water for the environment. … ”  Read more and download report at the PPIC here: Making the most of water for the environment: a functional flows approach for California’s rivers

Q&A: A faster track for ecosystem restoration

two people standing amongst tall trees.4 reasons meadow restoration is good for all of us

Meadows are often the subject of beautiful photographs and paintings, with colorful grasses swaying in the wind and creeks winding through the scene. But beyond their beauty, meadows provide important services to people and wildlife.  “Meadows are a great form of green infrastructure,” said Ian Vogel, a wildlife biologist in the U.S. Fish and Wildlife Service’s Sacramento Field Office. “They clean our air, contribute to a reliable water supply and provide essential habitat for wildlife.”  Vogel is part of a network of federal and state agencies and environmental groups known as the Sierra Meadows Partnership. The partnership creates and implements strategies to restore meadows throughout the Sierra. … ”  Read more from the US FWS here:  4 reasons meadow restoration is good for all of us

New water affiliates group forms at Scripps’ Center For Western Weather And Water Extremes

Atmospheric river storms cause 40-60 percent of annual precipitation and roughly 85-99 percent of flood damages on the West Coast. With atmospheric rivers vital to water supply and the main drivers of flooding, the Center for Western Weather and Water Extremes (CW3E)at Scripps Institution of Oceanography at UC San Diego this month has formed the Water Affiliates Group (WAG), a new annual membership program that brings together water agencies and other water resource stakeholders to share best practices in forecast informed reservoir operations,  better understand atmospheric river storms and drought, and strategize ways to improve water management that mitigate flood risk and increase water supply reliability.  …

Click here to continue reading this press release.

Many water operations in the West are strictly regulated by U.S. Army Corps of Engineers-approved water control manuals based on long-term averages of winter storms and spring runoff. A few private reservoirs in the region have used weather forecasts in operations. These manuals have traditionally operated on calendar-year directives to lower reservoir levels in October to make room to prevent winter storm runoff floods and raise levels in April, if it rains. A new federal policy now allows water managers to incorporate forecasted conditions in planning water operations and in updates to water control manuals, allowing operators to leverage advances in weather and water forecasting to better adapt to anticipated drought or storm conditions. 

CW3E is a leader in Forecast Informed Reservoir Operations (FIRO), which uses data from watershed monitoring and modern weather and water forecasting to help water managers determine the best course of action for retaining or releasing water from reservoirs depending upon the forecasted conditions. There are on-going FIRO projects at Russian River Basin (Lake Mendocino), the Santa Ana River Basin (Prado Dam), and the Yuba-Feather River Basins (New Bullards Bar and Oroville). As forecasting skill improves, and with more frequent and greater extremes in floods and droughts likely in the future climate, FIRO is aiding reservoir operators in developing procedures for leveraging improved forecasts within established guidelines. 

“The vision for the new Water Affiliates Group is to develop a strong network of like-minded water leaders to strategize and execute plans for research and applications developments that support best practices in forecast-informed water operations, and pioneer innovative solutions in water supply management that ultimately preserves public safety and saves money for ratepayers, ”said F. Martin (Marty) Ralph, director of the Center for Western Weather and Water Extremes at Scripps and a leading researcher studying atmospheric rivers.  

There are six founding partners of the Water Affiliates Group: Irvine Ranch Water DistrictOrange County Water DistrictSan Diego County Water AuthoritySonoma WaterTurlock Irrigation District, and Yuba Water Agency. Members of the Water Affiliates Group have the opportunity to share their perspectives with CW3E scientists and other water districts at the annual workshops and conferences that the Center convenes. 

CW3E has numerous tools and technologies that members of the Water Affiliates Group can use to augment water research and methods of implementation. These tools include research on water supply reliability, flood management, greenhouse gas mitigation, groundwater recharge, public safety, observations, forecasting, decision support, climate outlooks (months- to decades-long), and hazard assessment.

Commentary from founding partners on the new Water Affiliates Group:

“Ensuring water supply reliability is incredibly important for today’s water leaders.  The Water Affiliates Group has been formed at the right time and will help shepherd in a new level of industry networking and top-notch research that will support successful water operations throughout the state.” – Steven E. LaMar, Board of Directors, Irvine Ranch Water District

“We value our partnership with the Water Affiliates Group because it is a testament to true collaboration. Water and government agencies and leading researchers have come together to enhance water management to make California more resilient during times of drought,” stated Orange County Water District President Vicente Sarmiento.  “As part of this effort, the Orange County Water District is studying the feasibility of increasing water capture behind Prado Dam which would allow us to capture and use an additional 20,000 acre-feet, or 6.5 billion gallons, of stormwater in a wet year. This creates a new local water supply that is enough for 160,000 people―a tremendous benefit to our region that makes us less reliant on costly imported supplies.”

“This partnership with Scripps Institution of Oceanography underscores our commitment to strategic, science-based decision-making and long-term planning. By supporting advances in forecasting, we can more efficiently and effectively manage water resources both locally and statewide. This ultimately will benefit everyone in California by helping sustain our economy and quality of life.” — Jim Madaffer, Board Chair, San Diego County Water Authority

“Sonoma Water has worked with CW3E since its inception to brainstorm, create and implement successful state of the art water management tools, many that are being replicated across California. In the era of climate change, adaptation is mission critical.  Our partnership with CW3E as a founding member exemplifies the trust and ongoing support needed to meet these challenges together,” said Grant Davis, general manager, Sonoma Water.

“Turlock Irrigation District has been utilizing Scripps’ atmospheric river data to inform our reservoir operations for the last few years. Using this data has proven invaluable to our operations, improves public safety, and provides tremendous value to our customers,” said Turlock Irrigation District General Manager Michelle Reimers. “We are thrilled to be founding members of the Water Affiliates Group, and are excited to enhance our relationship with Scripps and continue using the latest technology to inform our water operations.”

“Our partnership with Scripps has been extremely productive and beneficial,” said John James, Yuba-Feather FIRO co-chair and Water Project Manager for Yuba Water Agency. “As a member of the new Water Affiliates Group, it’s exciting to continue to grow Scripps involvement with the Agency and leverage the remarkable research they provide for the benefit of both the people of Yuba county and the state.”

Study finds wastewater treatment plants could profit by processing food waste while reducing greenhouse gases

A new report issued today by the California Environmental Protection Agency shows that at least half of California’s landfill-bound food waste could be processed at the state’s wastewater treatment plants and serve as an innovative power source.  Waste can be “co-digested” at these facilities, which involves adding organic wastes including municipal food scraps and industrial food processing wastes such as chicken blood to a facility’s anaerobic digester.  Building on a survey of the nearly 225 wastewater treatment plants in California, the report finds that many have the existing anaerobic digestion capacity to accommodate diverted food waste. While maximizing the use of that excess capacity would require additional infrastructure investments, the report shows such investments would benefit California’s economy while advancing environmental goals.

Click here to continue reading this press release from Cal EPA.

“We release this report just as California is experiencing the very real impacts of climate change,” said Jared Blumenfeld, California’s Secretary for Environmental Protection. “As our environmental problems become more tangled, we have to start planning for cross-cutting solutions like this. Co-digestion can be a triple threat against climate change: it can reduce organic waste in landfills while cutting greenhouse gas emissions and helping to clean wastewater.”

The report estimates the statewide capital investments required to use the co-digestion capacity range between $900 million and $1.4 billion. The net benefits to the state could be up to $255 million each year. 

Maximizing co-digestion capacity could reduce statewide greenhouse gas emissions by as much as 2.4 million metric tons of CO2-equivalent per year. That’s more than half of the emissions from landfills that California committed to reducing by 2030.

“The report’s findings are very promising,” said State Water Board Chair E. Joaquin Esquivel. “It shows California’s wastewater treatment plants have the existing anaerobic digestion capacity to accommodate at least half of California’s landfilled food waste—likely more. We look forward to working with our industry partners to get more of these projects off the ground.”

The full report can be found on the SB 1383/Organics Diversion/Co-Digestion resource webpage.
