Banner - American River Levees

Caution Boaters and Swimmers! 
We are working to armor 2.5 miles of levee along both sides of the American River between Sacramento State University and Glenn Hall Park.
In this area, we have installed yellow barriers. These are placed in the river to help control sediment stirred up by construction activities;
however, they can present potential hazards to boaters and swimmers.
Please avoid the yellow barriers, follow the center of the river channel through construction, stay away from shorelines where major construction is underway.

Levee upgrades to build on recent flood risk management efforts

The Sacramento Metropolitan area is one of the most at risk areas for flooding in the United States due to its location at the confluence and within the floodplain of two major rivers. Significant levee improvements, primarily through the construction of 22 miles of seepage cutoff walls, were completed on the American River in 2016 as part of the Water Resources Development Act (WRDA) 96/99 project. Now, this project will add up to 11 miles of bank protection for Lower American River levees. But this portion includes more than just the American River. Sections of the Natomas East Main Drainage Canal (NEMDC), Arcade Creek, and Magpie Creek would be improved to address identified seepage, stability, erosion, and height concerns.
