The confounding statements from the state Department of Water Resources about the Lake Oroville spillway crisis just keep coming.The disaster has been a public-relations nightmare from the beginning, but DWR keeps making matters worse with its words and actions. As the repair bill for the crumbling spillway and the emergency response approached $200 million last week, DWR acting Director Bill Croyle — who has exhibited a troublesome tendency to downplay the incident since it started Feb. 7 — used an inappropriate analogy when asked at a press conference whether the crisis could have been prevented and who was responsible.
