SAN FRANCISCO (AP) - California officials are releasing expert reports into the troubled Oroville Dam after criticism that officials weren't telling the public enough about risks from two damaged spillways and the rush to fix them.

The state Department of Water Resources on Monday released two reports from engineers and other experts that the state had previously refused to make public.

The reports say cracks in the main spillway might have led to the main spillway's failure in February. Authorities ordered nearly 200,000 people to evacuate on Feb. 12 after both of the dam's spillways began collapsing.

California lawmakers, conservation groups and newspaper editorials last week stepped up demands for state and federal officials to share more information about risks and repairs at the Oroville Dam.
