Butte County Sheriff Kory Honea says the nearly 200,000 people who were ordered to leave their homes over the weekend out of fear that the emergency spillway at Oroville Dam could collapse may not be able to return until that spillway at the nation's tallest dam is repaired.
Helicopters are being used to drop loads of rock on the eroded spillway at Lake Oroville, about 150 miles northeast of San Francisco. Forecasters say more rain is expected this week.
Department of Water Resources officials continue to allow water to flow from the primary spillway at the dam in an attempt to reduce the lake level by 50 feet before another large winter is forecast to slam into Northern California.
A flash flood warning for Central Butte County due to the Oroville Dam situation will remain in affect until 4:15 p.m. on Tuesday.
