Water flow slowing over emergency spillway at tallest US dam

Officials say water will continue to flow over an emergency spillway at the nation's tallest dam for another day or so.

Water began flowing over the emergency spillway at the Oroville Dam in Northern California on Saturday for the first time in its nearly 50-year history after heavy rainfall.

California Department of Water Resources spokesman Eric See said at a Sunday press conference that skies are clear and the overflow is steadily slowing. It's expected to stop by midday Monday.

In addition to the emergency spillway, water also flowed through the main spillway that was significantly damaged from erosion. Officials said they'll assess the damage starting Monday.

See stressed the dam is structurally sound and there was no threat to the public.

About 150 miles northeast of San Francisco, Lake Oroville is one of California's largest man-made lakes.
