Independent research and analysis of California's developed water systems
Jay Lund published a clever satire of California water rhetoric today, and he's right that policy-based evidence-making occurs in our water debates. I worked with Jay and other Delta Independent Science Board members in 2021 to save the Delta Independent Science Board from defunding, and I value his truthtelling. But Jay's framing misses something critical … Continue reading Response to Jay Lund’s “Nine California Water Rites”

In 2015, the Department of Water Resources filed a petition for Change in Point of Diversion with the State Water Resources Control Board for the WaterFix / twin tunnels project. Environmental, fishing, and Delta groups strongly protested the Water Board proceeding with the hearing before the Bay-Delta Water Quality Control Plan Update. But the Hearing … Continue reading History: Water Board ruled against delaying twin tunnels CPOD hearing for Bay-Delta Plan update

Governor Newsom's new salmon strategy breathlessly commits to the following: By 2025, begin to use biological indicators, referred to as biological goals, to inform decision making during implementation of the updated Bay-Delta Water Quality Control Plan. (SWRCB). But biological goals for salmon have been part of the Bay-Delta Water Quality Control Plan since the 1995 … Continue reading Governor’s new salmon strategy ignores existing biological goals
On Wednesday, October 4, 2023, the State Water Resources Control Board held a hearing on proposed regulations to implement 2018 legislation to make conservation a way of life in California. According to the Board's fact sheet: Making Conservation a California Way of Life is a new regulatory framework proposed by State Water Board staff that establishes … Continue reading Comments on the Water Board’s draft urban conservation regulations
The US Geological Survey's ARkStorm studies included extensive analyses of vulnerabilities to flooding. In 2016, USGS Researchers Geoffrey Plumlee, Charles Alpers, Suzette Morman, and Carma San Juan published “Anticipating Environmental and Environmental-Health Implications of Extreme Storms: ARkStorm Scenario.” The ARkStorm 1.0 scenario found extensive flooding of the San Joaquin Valley and the Tulare Lake basin … Continue reading USGS ARkStorm 1.0 study showed high risk of contamination from Tulare lake basin flooding
The Delta Lead Scientist, Dr. Laurel Larsen, is a hydroecologist at the University of California’s Berkeley campus. She is the first mid-career scientist to hold the position of Delta Lead Scientist, having received tenure in 2018. The Lead Scientist position and the Delta Science Program were first created under the 2000 CALFED Record of Decision, … Continue reading Delta Lead Scientist creates unprecedented conflicts of interest with multi-million dollar UC research grants
The Newsom administration's strategy for dealing with flood flows relies heavily on diversions to farmland for groundwater recharge. But flooding in the Tulare basin this year is showing how orchards are not resilient to floods. And orchards have also not been resilient to recent droughts. This is what happens to an almond orchard in full … Continue reading Orchards are not resilient to floods or droughts
