Lake Manitoba update: August 7, 2017

The update was delayed as I was unable to access the Environment Canada site yesterday; it is still very slow to respond today.

The theme for this week is down. Rivers and lakes are all down in the summer heat. Lake Manitoba dropped nearly 2/10ths of a foot to 813.08 feet. With the lower lake level, outflow on the Fairford River is down to 11,336 cfs. Lake Winnipegosis is down to 833.92 feet, and as a result flow on the Waterhen River is down to 9,994 cfs. Lake St. Martin fell this week to 803.05, still above flood level. Flow on the Assiniboine is now a trickle, being 749 cfs at Holland and 777 cfs at Headingly.
