Lake Manitoba update: Nov. 19, 2017

With growing ice cover, we are starting to get a good read on lake levels. Lake Manitoba is registering 812.27 feet this morning, below the top end of its operating range of 812.5 feet. Upstream on Lake Winnipegosis the level is unchanged from last week at 832.51 feet. This level is roughly 2 feet above its average level for this time of year and continuing high water on Lake Winnipegosis keeps the level of Lake Manitoba high. Ice is currently affecting the gauges on the Waterhen River. Fairford flows remain high currently registering 8,193 cfs. The level of Lake St. Martin is up this week to 801.36 feet. Flow on the Whitemud River is a trickle at 31 cfs. The Assiniboine flows are now 1,134 cfs at Holland. Flow at Headingly (1324 cfs) jumped in the last few days in a manner suggesting that the gauge is ice affected. The Shellmouth Reservoir continues to drop and is now 1,398.72 feet.
