Gallery: Oroville Dam repairs in full swing

Repairs of the spillway structure on the Oroville Dam in California are well underway. 

The failure of the spillway in February 2017 led to water being diverted down an earthen emergency spillway which had not been used since the dam was completed in 1968.

The incident occurred after the Department of Water Resources (DWR) started to discharge water over both the main and emergency spillway in order to control water levels impounded by the dam.

High water flows led to both spillways being damaged and concerns that the erosion could led to the collapse of the earth embankment dam, which is the highest in the US at 230m, and resulted in over 180,000 people being evacuated from their homes.

In February this year GE reported that the managment of the Oroville Dam was being sued over the failure by more than 40 local businesses, farms and property owners.
