The State Water Resources Board has released the draft of a Scientific Basis Report that looks at fisheries and water flows in the Sacramento River and Bay-Delta region. The area supplies 80 percent of the Valley’s water. The report issued Oct. 19 follows by several weeks a draft study sent out for comment on the other major river that flows into the Delta, the San Joaquin River, which feeds the federal Central Valley Project. Zone 7 Water Agency is suppled by the State Water Project from the Shasta Dam on the Sacramento River.
