UPDATE (12:50 a.m.)—Conowingo Dam officials said seven gates were open just after midnight Saturday, and they may open up to 10 gates by 8:30 a.m.

"Drove through the Conowingo Dam Car Wash this morning," one Twitter user said Thursday. "Some serious spray coming over the wall."
By 4:30 p.m. Friday, officials had opened seven gates total and said the dam was operating under spill conditions.
