oroville, calif. — the latest on problems with an emergency spillway at the nation's tallest dam (all times local):

11:45 a.m.

the chief executive of the oroville hospital says it is operating normally but that 100 patients have been moved to the hospital's second floor.

hospital ceo robert wentz says the hospital took the step monday morning "out of an abundance of caution."

the hospital is outside the flood zone below the dam on oroville lake and sits on a hill.

wentz says evacuating acutely ill people is difficult so it is usually better for them to stay where they are.

he says patients will not go back to the hospital's first floor until authorities tell the hospital it is safe to do so.

state officials are waiting for the light of dawn to inspect an erosion scar on the potentially hazardous emergency spillway at northern california's oroville dam.

california department of water resources action director bill croyle says officials in helicopters overflew the spillway sunday night to visually inspect it.

evacuations for at least 188,000 people living below the dam were ordered sunday after officials warned the emergency spillway was in danger of failing and unleashing uncontrolled flood waters on towns below.

water levels at the huge dam are continuing to drop and stopping water from spilling over the emergency spillway.

california department of water resources officials say flows into the lake are just under 45,000 cubic feet per second. outflows remain high at nearly 100,000 cubic feet per second.

water levels at northern california's lake oroville are continuing to drop and stopping water from spilling over a big dam's potentially hazardous emergency spillway.

evacuations for at least 188,000 people living below the dam were ordered sunday after officials warned the emergency spillway was in danger of failing and unleashing uncontrolled flood waters on towns below.

california department of water resources officials say flows into the lake are just under 45,000 cubic feet per second. outflows remain high at nearly 100,000 cubic feet per second.

officials ordered the evacuation because possible failure of the emergency spillway could send a 30-foot wall of water into communities.

state fire and rescue chief kim zagaris says at least 250 california law enforcement officers are in the area of the dam and evacuation routes to manage the exodus of residents and ensure evacuated towns don't face looting or other criminal activity.
