Water was reportedly five feet high in some homes, causing significant damage. Water rose four feet high in the lower level of the Renaissance Hotel on Stemmons Freeway near Wycliff Avenue. Dallas police received more than 240 calls about people in danger from the flood waters in four hours. A woman was swept away in Turtle Creek by Wycliff Avenue after she abandoned her car due to rapidly rising flood waters. Her body was recovered later that night nearly a mile from were she was swept away.
