Work continues on a boil on a Sacramento River levee near the Natomas Cross Canal.

Joe Henderson is the General Manager of Reclamation District 1001. He says crews are installing a seepage wall on an 870-foot section of levee along the Garden Highway north of Elverta Road.

"They put down a filter fabric first and then they put rock over it to keep it in place and that helps support the levee and keep the levee dirt material in place," says Henderson.

He calls the work an "emergency pre-emptive repair." He says most levees are prone to seepage.

"As long as it's running clear, that's what we want. When it starts to move material, that's when we start monitoring closely and progress from there."

Henderson says the levee system is in pretty good shape considering the amount of pressure on it this winter. The district plans to begin work soon on another section of levee up-river from the boil site.
