Rainfall in the upper Fraser River and North Thompson River watersheds is bringing up the fast-running Fraser River in the next day or so, says the B.C. River Forecast Centre.
The Fraser should peak at six metres at the Mission gauge on Wednesday, Maple Ridge district said in a news release.
But that is still below the 2007 level, when flood fears were heightened.
The District of Maple Ridge has been doing daily dike patrols since early June and staff have been in regular contact with colleagues in the lower Fraser Valley, monitoring the conditions and forecasts for each five-day weather cycle.
Prior to this recent expected slight increase, water levels peaked at 5.65 metres from June 10 to 15.
