I donot think we have anything to worry about here where we live, for the reasons you mentioned. South Fort George gauge up .111 which is a little over 4 inches, in over 13 hours.
Hope, up a little over 3 inches in the same time period. Mission is up 10 inches but it could be because of the tidal effect, as the water nears the river mouth and backs up some. Of course you have the Vedder and Harrison that adds to the runoff, both being below the Hope gauge and will effect the Mission gauge.
I am no expert on how much the tide and being near the river estuary effects things.
Also in 1948, the big flood year the Mission gauge reached 8.2 we are now at 5.69 which is 8 feet lower than 1948's level, discharge rate was 15,300.
In 1972 another high water year Mission gauge was 7.4 so we have nearly 6 feet to reach that level. Discharge was 13,000. Right now it is 10,000
I have also talked to a few people in the know on the current situation and I will go out on a limb and say we will be okay here unless we get a lot of rain and warm temperatures in the next week or so. The flooding going on now is homes that do not have dyke protection The low temperatures have helped as well of course but maybe will be adding some snow pack for next year.
I have layed my cards on the table with these facts, time will tell if I win this poker game.
I have not checked the snow pillows throughout the province to see how the water content is doing, will later.
