St. Louis ? Two children whose home was hit by the massive flood surge from a reservoir break were released from a hospital Sunday.

Three-year-old Tara Toops and her 7-month-old brother Tucker were discharged from Cardinal Glennon Children’s Hospital in St. Louis, hospital spokesman Bob Davidson said. Another sibling, 5-year-old Tanner, remains in critical condition at the hospital.

The injured youngsters are children of state park Supt. Jerry Toops and his wife, Lisa, whose Lesterville home was ripped from its foundation Wednesday after a 660-foot-wide, V-shaped section of wall around a mountaintop reservoir toppled and unleashed a torrent of water.

About a billion gallons of water rushed through the breach, but the Toops home was one of the few structures affected.
