Thanks Scott for the most recent update that follows. Lake Manitoba update: January 2, 2024
The New Year brings a relatively uneventful update. Precipitation has been light, and water levels / river flows do not show any big changes from the last update in November. The level of Lake Manitoba is currently 811.25 feet, slightly higher (0.06 feet) than the level on Nov. 1 and is still in the lower half of its desired operating range. Outflow at Fairford has increased to 2,151 cfs, which is still low for this time of year. The level of Lake St. Martin is has risen slightly from November to 798.29 feet, still near the midpoint of its operating range. Flow on the Dauphin River is up to 4,556 cfs. Flow on the Waterhen River has fallen to 1,462 cfs, very close to the average flow for this time of year. The level of Lake Winnipegosis is down slightly to 830.05 feet, about 3-inches below its average level for January. The gauge on the Whitemud River is currently offline. Flow on the Assiniboine is currently 1,999 cfs at Holland and 1,275 cfs (and rising) at Headingly. The province is dropping the level of the Shellmouth Reservoir, which has increased Assiniboine flows since November. The current level of the reservoir is 1399.50 feet, about 1.4 feet lower than early November.
