Dramatic new images show scale of damage to Oroville Dam spillway
Geologists attempted for the first time Tuesday to figure out what to do about the vast, yawning canyon dug out of the earth after a crater opened up in the Oroville Dam’s concrete spillway and diverted water at high speed into the adjacent hillside.
Monday’s shutoff of water flowing down the main spillway revealed a shocking panorama of damage, forcing experts with the California Department of Water Resources to scramble to figure out how the crippled chute can possibly be fixed by the end of the year — in time for the next rainy season.
Photographs and video released by the department Tuesday showed that an enormous section of the spillway, which is as wide as a 15-lane freeway, had been wiped out. In its place is a giant rocky channel carved out of the earth leading down to the Feather River.
