A preliminary report released a week after the Oct. 1 surge later found human error related to the programming of the control system was the "clearest contributing factor" in the tragedy. "Metro Vancouver continues to co-operate fully with external agencies in their investigations and will not be providing further comment at this time," said the regional district in a statement. When the water surged down the river, rising by three metres in a matter of minutes, it hit a popular fishing spot where a number of anglers were fishing. Two people pulled into the water were rescued and two swam to shore. Others standing near the water managed to scramble to higher ground before they were hit by the surge.
