Water from the rain-swollen Sacramento River is spilling over a 33.5-foot-high concrete wall and into a bypass built to divert flood water.

NOAA hydrologist Robert Hartman said Sunday the overflow is expected to reach a depth of three feet on Tuesday then start receding. It’s the first time water has spilled over the so-called Fremont Weir crest and into the Yolo bypass since 2012. The nearly 2-mile-long concrete wall is located about 8 miles northeast of Woodland.
