A judge has ordered a Fresno-based water district to stop working on plans to raise the height of Shasta Dam.

The Westlands Water District, which provides irrigation water to farmers on the west side of the San Joaquin Valley, was working on a report assessing the environmental impacts of raising the height of the dam.

But a judge ruled that Westlands’ work violated a state law that prohibited local and state agencies from participating in any projects that would have an adverse impact on the McCloud River.
