****Thanks to Dr. Scott Forbes for the following post *****
The fall update finds little to worry about as we head toward winter. The lake and rivers are all close to average long-term levels. Lake Manitoba is currently sitting at 811.28 feet, a bit below the midpoint of its operating range. Outflow at Fairford is modest at 2,235 cfs, slightly above its long-term average. The level of Lake St. Martin is 798.02 feet, well within its desired operating range. Flow on the Dauphin River is 2,765 cfs. Flow on the Waterhen River is 3,136 cfs, about 300 cfs below its median flow for this time of year. The level of Lake Winnipegosis is currently 830.24 feet, right at its average level for early October. Flow on the Whitemud River is currently 60 cfs and falling. Flow on the Assiniboine is 819 cfs at Holland: that is slightly above the long-term average for this time of year. The gauge at Headingly is currently offline. The Shellmouth Reservoir is falling slowly, and is currently at half a foot below its median level for this time of year, sitting at 1400.27 feet. Overall, as winter approaches there is nothing worrisome in the long-term outlook. Flows and lakes levels neither too high, nor too low: like Goldilocks, right in the middle and just right.
