DWR 2006 study: “too much risk” taken with reservoir operations

In 2006, for the first California Climate Assessment, DWR published a study of operations of the State Water Project and Central Valley Project with climate change. The report was titled, "Progress on Incorporating Climate Change Into Management of California’s Water Resources." DWR's 2006 modeling predicted the current crisis, with Shasta, Folsom, and Oroville reservoirs being … Continue reading DWR 2006 study: “too much risk” taken with reservoir operations

On scientific confluence and the challenges of avoiding a ghastly future in California water

Seventy years ago, psychologists Fritz Perls, Paul Hefferline, and Richard Goodman defined confluence as considering different viewpoints and assimilating them into one's own worldview [1]: At the end of any successful experience – one that is not interrupted but allowed to complete itself – there is always a confluence of energy or energy producing materials. … Continue reading On scientific confluence and the challenges of avoiding a ghastly future in California water

DWR Chief Engineer warned of climate change draining northern California reservoirs

Governor Newsom’s drought emergency declaration is a direct consequence of the draining of Shasta, Folsom, and Oroville reservoirs by the Central Valley Project and State Water Project to export water from the Delta. Emergency operation of these major reservoirs will be a disaster for the Delta ecosystem, and will also have severe impacts on Delta … Continue reading DWR Chief Engineer warned of climate change draining northern California reservoirs

Update: Bay Delta Conservation Plan & Climate Change

In August, 2012, California Water Research released a report, Incorporating Drought Risk Into California Water Resources Planning.  Since that time we have been waging a quiet campaign for the Department of Water Resources to recognize that their climate modelling for the Bay Delta Conservation Plan has significant limitations and inconsistencies. The report says that, if the projections … Continue reading Update: Bay Delta Conservation Plan & Climate Change
