Oroville Dam

One year after the Oroville Dam’s concrete spillway ruptured on Feb. 7, 2017, crews working day and night have made the most critical repairs to what has become an $870 million project. Kiewit Corp. of Omaha, Neb., fixed the dam’s main spillway and an emergency spillway that also was damaged by unprecedented water releases forced by record rainfall in Northern California.

The work has continued in 2018, while the California Department of Water Resources (DWR) and Washington, D.C., discuss the extent to which the Federal Emergency Management Agency will pay for repairs. Meanwhile, Governor Jerry Brown signed legislation that codified the annual inspections DWR already conducts of the vast majority of the 1,249 dams the department oversees. The law requires “low hazard potential” dams be evaluated at least every other year.
