A preliminary report has found human error was "the clearest contributing factor" in a deadly incident at the Cleveland Dam in North Vancouver, B.C., the regional district said Thursday. Two men, father and son, were killed downstream when the spillway gate opened unexpectedly during maintenance on Oct. 1, releasing a freezing torrent of water into the Capilano River. "While the review continues, we can now confirm that the clearest contributing factor was human error related to programming of the control system for the spillway gate at the Cleveland Dam," Metro Vancouver commissioner Jerry Dobrovolny said in a statement. On Thursday, Metro Vancouver said the 2002 errors happened while the district was in the process of upgrading the spillway gate. There is no siren or alarm system in place to warn people in the river if the dam malfunctions.
