YOLO COUNTY, Calif. —

In the Sacramento and San Joaquin regions, more than a thousand miles of levees protect farms and communities, but these aging structures are vulnerable to floods and earthquakes.

When there is a lot of water coming down the rivers, a system of weirs can take pressure off the levees by moving water into bypasses.
