Narrated Presentation describing construction activities associated with our Sacramento River East Levee Contract 1 work, scheduled to begin March 30, 2020. This presentation was created to replace the public meeting, previously scheduled for March 12.
From mavensnotebook.com – “Following a comprehensive outreach and recruitment effort, the Sites Project Authority Board of Directors has selected Jerry Brown as the Executive Director for Sites Reservoir. Jerry Brown previously served as general manager of Contra Costa Water District where he oversaw the operations and management of a large water system that served more than 500,000 customers. In this role, he also oversaw development of the first Los Vaqueros Reservoir expansion in 2012. Since leaving CCWD in 2019, he has been working closely with Bay Area water agencies, refuge managers and Central Valley water users to develop the second expansion of Los Vaqueros as a regional asset funded by Prop 1, similar to Sites Reservoir. … “ (more).
From American Greatness – The rains bypassed sunny California in January and February, encouraging talk of another drought. California’s last drought was only declared ended about a year ago, after two wet winters in a row filled the state’s reservoirs. To cope with the last drought, instead of building more reservoirs and taking other measures to increase the supply of water, California’s policymakers imposed permanent rationing. This predictable response ignores obvious solutions. Millions of acre-feet of storm runoff could not only be stored in new reservoirs but also in underground aquifers with massive unused capacity. Additional millions of acre-feet could be recovered by treating and reusing wastewater, and by joining the rest of the developed nations living in arid climates who have turned to large scale desalination. All of this, however, would require a change in philosophy from one of micromanagement of demand to one that emphasizes increasing supply. (more)
From AccuWeather – After an absence of major storms for much of the winter, the ‘March Miracle,’ in terms of wet weather, seems likely to continue next week in California. The storm that brought drenching rain and yards of snow to the Sierra Nevada early this week has now all but cleared out of the state of California. A lull in storms is forecast late this week to this weekend, but a new series of storms is destined to impact much of the West next week with more rain and mountain snow from Monday to Wednesday. “It looks like a general 1 to 3 inches of rain during the first half of the week for California alone,” AccuWeather Senior Meteorologist Brett Anderson said. The most frequent rain may focus from just north of Los Angeles to the Oregon border, but some periodic rains will sweep through the L.A. Basin to San Diego and the deserts as well. (more)
New Forecast Tool Looks Three Weeks Ahead for Chances of Atmospheric Rivers – The Storm Type Key to Water Supply and Flooding, that Can Break U.S. West Coast Droughts, and Douse Wildfires
From Center for Western Weather and Water Extremes – While the Pacific Northwest experienced serious flooding in January and February, areas farther south are bracing for drought after an extremely dry winter. People in these dry regions are hoping for a “Miracle March” to deliver substantial rain and snow to alleviate drought risk. However, a new experimental forecast tool looking out as far as three weeks shows little chance of this happening. The tool focuses on the odds of atmospheric rivers hitting the region over the next three weeks. Atmospheric river storms can deliver up to half of California’s total annual precipitation and cause 90 percent of flooding in the state, while a lack of enough of these storms can lead to drought.

From CAAg Today Radio –The first bill introduced by Representative Josh Harder (CA-10), the Securing Access for the Central Valley and Enhancing (SAVE) Water Resources Act passed in the Natural Resources Committee today on a vote of 19-12. The bill provides a wraparound approach to addressing water issues facing the Central Valley by supporting local water storage projects, spurring innovation, and making long-overdue investments in our aging water infrastructure. This is the final step in the legislative process before the bill receives a vote in the full House of Representatives. The SAVE Water Resources Act touches on a broad range of water policy areas aimed at increasing water storage opportunities, spurring innovation in water sustainability, and making responsible federal investments in our aging water infrastructure.

From DredgingToday.com –This project will kick off major construction in the region to complete approximately $1.5 billion of work to upgrade levees along the American and Sacramento Rivers as well as widening the Sacramento Weir and Bypass. The project is part of the American River Common Features program work, which is a collaborative effort between USACE, California’s Central Valley Flood Protection Board, California Department of Water Resources and the Sacramento Area Flood Control Agency (SAFCA) to modernize Sacramento’s aging flood infrastructure for more than 500,000 people in the greater Sacramento region.

From inside climate news –Across hundreds of mountaintops, from the Sierra Nevada to the Sawtooths, Wasatch and Colorado Front Range, cloud seeding experts are now often burning small amounts of silver iodide with the aim of bolstering dwindling water supplies. The vaporized metal particles are ideal kernels for new ice crystals. When moist, super-cooled air rises over mountain ranges under predictable winds, it sets up perfect conditions for the crystalline alchemy that creates snow, the white gold craved by ski resorts, ranchers and farmers and even distant cities that need mountain water to survive. The scramble for water has intensified as global warming has battered much of the West during the last 20 years with heat waves, droughts and wildfires. With projections for declining snowpack and river flows, cloud seeding is becoming a regional climate adaptation measure costing several million dollars each year. In other regions, including parts of the central United States, seeding has also been used to try and enhance summer rains and to reduce the risk of severe hail storms. (more)
Without $175M levee upgrade thousands in Manteca, Lathrop would need flood insurance
From Manteca/Ripon Bulletin –Failure of levees during a 200-year event would send three feet or more of water to cover almost all of Lathrop, flood neighborhoods in Manteca southwest of the Airport Way and 120 Bypass interchange as well as inundate the first floor of the 500-room Great Wolf Lodge and indoor water park. Areas in the City of Manteca where almost 4,000 homes have been approved west of McKinley Avenue along with the existing Oakwood Shores development could be covered with more than 10 feet of water. The same applies for the new Wayfair distribution center in Lathrop along the 120 Bypass. Protecting against a 200-year flood — which references the magnitude and not the frequency of flooding — is a state mandate that must be in the process of physically be constructed by 2025 or else all development will stop in the identified areas.
