Lake Manitoba update: June 25, 2017

Strong winds continue to make estimating the level of Lake Manitoba difficult. The rough estimate is that the level is currently 813.50 feet with north winds driving up the level of the south basin. The current level is roughly the same as last week. It appears that the level of Lake Manitoba is declining very slowly from a peak of roughly 813.7 feet. Lake St. Martin remains at flood level, sitting at 803.30 feet this week. Flow on the Fairford River remains high (11,654 feet), as does flow on the Waterhen River (11,901 cfs). Both rivers are affected by the wind direction. North winds lower the level of the north basin of Lake Manitoba, reducing outflow at Fairford. The same winds push water into the south end of Lake Winnipegosis, causing Waterhen flows to rise. Lake Winnipegosis remains high this week at 834.65 feet which is keeping Waterhen flows high. Flow on the Whitemud River fell this week to 388 cfs. Flow on the Assiniboine fell to 1,907 cfs at Holland but is 3,094 cfs at Headingly. The mismatch suggests a possible gauge error.
