Lake Manitoba update: Jan. 31, 2016

Lake Manitoba rose slightly this week, likely due to the precipitation that fell – the weight of the snow on the ice raises the level of the lake. The lake is currently sitting at 811.73 feet, up two hundredths of a foot from last week. The level of Lake St. Martin was unchanged from last week, sitting at 800.68 feet. Outflow at Fairford rose slightly to 5,013 cfs. The gauge for the Waterhen River remains offline this week. The Whitemud flow remains very low (51 cfs) while flow on the Assiniboine continues to fall, reading 1,341 cfs at Holland, and 1,313 cfs at Headingly.

Lake Manitoba update: Jan. 17, 2016

A bit of good news. It appears that the ice affected gauges have been calibrated over the last week and so we can get a much better idea of what is currently going on. Lake Manitoba continues to fall but very, very slowly. We are down three hundredths of a foot this week to 811.73 feet. Inflow from the Waterhen is currently 2,471 cfs, about half of the outflow at Fairford of 5,013 cfs. Flow at the Whitemud is negligible at 51 cfs. Lake St. Martin is rising rapidly, up about 1/6th of foot over the last week to 800.54 ft. The Assiniboine gauges are currently registering just under 1,800 cfs, treble the average flow for this time of year.

Lake Manitoba update: Jan. 10, 2016

The ice continues to play havoc with the gauges this week. Looking at the gauge readings, flow on the Waterhen apparently fell from over 9,000 cfs on Tuesday to zero today, neither of which is true. The Assiniboine gauges have been behaving erratically all week and it is not possible to tell what the actual level of flow is. But according to the latest provincial flows on the Assiniboine are unseasonably high, a worrisome indicator for the spring thaw.

The Lake Manitoba gauges appear to be functioning normally and the level of the lake remains little changed from the last update, currently sitting at 811.76 feet. Lake St. Martin has risen to 800.38 feet, with flows at Fairford currently at 5,136 cfs. The Whitemud flow remains very low at 64 cfs.

New Year’s update for Lake Manitoba

I’ve been away since early December hence the delayed update. I’ll continue to post updates each Sunday starting on the 10th. Not much is changing these days. Lake Manitoba is down slightly since the last update, currently sitting at 811.79 feet. This means that the data from the Waterhen are still ice affected and reading too high. The gauge reading is currently 6,531 cfs, higher than the gauge reading for Fairford, which is 5,277 cfs. If that were true, Lake Manitoba would be rising, not falling (slowly). The Whitemud flow is basically zero (113 cfs). Flow on the Assiniboine is also uncertain as the gauges are ice-affected, reading over 5,000 cfs at Holland and 3,000 cfs at Headingly. Lake St. Martin now sits at 801.26 feet, up very slightly (0.03 feet) since the last update.
