Lake Manitoba update: Oct. 16, 2017

Lake Manitoba appears to be down from last week with current estimate of the level of Lake Manitoba is 812.43 feet. If that is true, then the lake is back inside its operating range. There are some odd gauge readings, however, that are not matching up with the prevailing winds. The level at Steep Rock is currently falling, but winds are from the southwest, so the Steep Rock gauge should be rising. Thus the estimate of lake level should be viewed with some suspicion. Fairford flows are down to 8,582 cfs, as are flows on the Waterhen (7,487 cfs). The estimate of the level of Lake Winnipegosis is down this week to 832.45 feet. The level of Lake St. Martin is almost unchanged this week at 801.74 feet. The Whitemud River is now running at 109 cfs. Flow on the Assiniboine is 833 cfs at Holland; the gauge at Headingly is currently offline.

One thought on “Lake Manitoba update: Oct. 16, 2017

  1. Could the odd gauge readings be a set up. You know a set up for” we are not responsible for” the imminent flooding of the Lake Manitoba South Basin this fall as in “we are not liable for damage because the lake was in the normal operating range”? Just saying.
