Governor Jerry Brown and administration officials claim that the California WaterFix, a controversial plan to build two 35-mile long tunnels under the Sacramento-San Joaquin River Delta, is based on science.
“The best scientific thinking says California needs the project,” Governor Brown told Dan Morain, Sacramento Bee editorial page editor, in an interview in December of 2016.
However, federal scientists strongly disagree with Brown’s claim that “best scientific thinking" supports the construction of the tunnels. In fact, the National Marine Fisheries Service (NMFS) has released a draft biological opinion documenting the harm the tunnels would cause to salmon, steelhead, Delta and longfin smelt, other fish and wildlife species, and water quality.
An independent peer review panel found the NMFS findings are backed by comprehensive analyses, new data, and modeling, according to a statement from the Golden Gate Salmon Association. The panel further found NMFS used the best available science and produced evidence of significant adverse impacts to species and critical habitat, including unacceptable harm to salmon.
