200, 000 Asked To Flee California Spillway
Emergency crews early on Monday prepared loads of rock to be dropped by helicopters to seal a crumbling spillway that threatens to inundate communities along the Feather River in Northern California, local media reported.
Almost 200,000 people were ordered on Sunday to evacuate from the area below the Lake Oroville Dam, the tallest dam in the United States, after authorities said its emergency spillway could give way.
Officials said the situation seemed less dire overnight but Sacramento television station KCRA reported that helicopters from around the state were sent to drop chest-high bags of rocks to close the hole in the spillway.
The NBC affiliate showed dump trucks dropping off piles of rock, which were then loaded into the bags with backhoes. The operation to close the gap would begin as soon as it was feasible, the station said.
The state Emergency Services Office and Department of Water Resources did not immediately respond to requests for comment.
The water department said on Twitter on Sunday afternoon that the spillway next to the dam was “predicted to fail within the next hour” but it remained standing.
The department said authorities were releasing water to lower the lake’s level after weeks of heavy rains in drought-plagued California.
Overnight, state and local officials said the immediate danger had passed with water no longer flowing over the eroded spillway but they cautioned that the situation remained unpredictable.
“Once you have damage to a structure like that it’s catastrophic,” acting Water Resources director Bill Croyle told reporters. But he stressed “the integrity of the dam is not impacted” by the damaged spillway.
The earthfill dam is just upstream and east of Oroville, a city of more than 16,000 people north of the state capital of Sacramento.
