Lower American River Erosion Control
Aerial image of flood risk reduction work on the American River in Sacramento, Calif., Feb. 1, 2023. The U.S. Army Corps of Engineers Sacramento District began work on erosion control measures along the American River in October 2021. The flood risk reduction measures were in place when heavy storms caused high water flows through the project site. The work held up incredibly well with only minor repairs to environmental features needed to return it to pre-storm conditions.
