Winter is settling in and ice is forming on the lakes and rivers. We are now getting a good look at the level of Lake Manitoba: it is sitting at 811.55 feet this morning. Ice still appears to be affecting the gauge reading on the Waterhen River (5,862 cfs): flow on the Whitemud River continues to fall, dropping to 123 cfs today. Outflow at Fairford is currently 2,617 cfs. Lake Winnipegosis is sitting at 830.56 feet this morning, near its long-term average level for this time of year. Lake St. Martin is starting to rise, and has reached 798.48 feet this week. Flow on the Dauphin River is up from last week to 4,768 cfs: that reading may be ice affected. Flow on the Assiniboine is 1,674 cfs at Headingly: ice appears to be affecting the gauge at Holland. The level of the Shellmouth Reservoir is now dropping steadily, sitting at 1401.41 feet today.
