It is another week of little change, but warming temperatures now hint that the spring freshet is not far off. The level of Lake Manitoba continues its slow decline, falling to 811.38 feet this morning. Inflow from the Waterhen River that has fallen to just 484 cfs. Inflow from the Whitemud River is a trickle at 49 cfs. Outflow at Fairford inched downward to 2,613 cfs. The gauge on Lake Winnipegosis appears to be malfunctioning, showing a five foot rise in water level since last week which doesn’t seem terribly likely. The gauge on the Dauphin River now appears to be functioning, registering a flow of 2,483 cfs. The level of Lake St. Martin is little changed from last week sitting at 799.34 feet today. The Assiniboine at Holland shows a flow of 1,010 cfs. The flow at Headingly is slightly higher at 1,183 cfs and has been rising since mid-week. The primary gauge on the Shellmouth Reservoir is behaving erratically, and is not giving the same reading as the secondary gauge, so there is no estimate this week.
