A U.C. Davis researcher said today that the proposed twin tunnels could reduce the proliferation of hyacinth and other invasive aquatic weeds.
That’s because the Delta would likely grow saltier, said Shruti Khanna, a postdoctoral researcher with the Center for Spatial Technologies and Remote Sensing.
“There will be seasonality in the salinity,” she told the Senate Subcommittee on Invasive Species during a hearing in Stockton. “During high flows the water will be fresh, and in the low-water season more saline. That higher salinity will control the species…. One of the major reasons they’ve been able to invade the Delta so well is because it is so fresh, all throughout the year.”
Of course, local agriculture depends on keeping the Delta fresh, too. We won’t get into that just now.
