Lake Manitoba update: Feb. 18, 2018

It is a week where almost everything, river flows and lake levels, is down. The level of Lake Manitoba fell to 811.86 feet. As the lake level falls, so does the outflow at Fairford, which is now 5,845 cfs. Inflow from the Waterhen River is also falling and is now 2,331 cfs. The gauge on the Whitemud is still offline. Lake St. Martin fell this week to 802.07 feet. The level of Lake Winnipegosis is unchanged on the week at 832.32 feet. Flow on the Assiniboine fell to 682 cfs at Holland and 718 cfs at Headingly. The Shellmouth Reservoir rose slightly to 1,395.81 feet.

Lake Manitoba update: Feb. 11, 2018

Another week of slow and steady change. The level of Lake Manitoba has fallen slightly to 811.89 feet. As the lake level falls, so does the outflow at Fairford, now 6,092 cfs. Inflow from the Waterhen River is also falling and is now 2,499 cfs. The gauge on the Whitemud is still malfunctioning but it is still safe to say that it still at a trickle. Lake St. Martin rose this week to 802.11 feet. Lake Winnipegosis is also up this week to 832.34 feet. Flow on the Assiniboine is still low, being 821 cfs at Holland and 805 cfs at Headingly. The Shellmouth Reservoir rose for the first time in a very long time, and is now 1,395.80 feet.

ALMS puts in voice on environment review

Below is the letter ALMS submitted

Association of Lake Manitoba Stakeholders

To: The Canadian Environmental Assessment Agency

The Association of Lake Manitoba Stakeholders (ALMS) represents resident associations, farmers and ranchers in communities bordering Lake Manitoba affected by the flood of 2011.

We believe that The Manitoba Clean Environment Commission should complete an independent review as mandated. Numerous public consultations have been sponsored by both the former and present government of Manitoba. Evidence of the effectiveness of the process and that the voice of communities was heard by government are the modifications of the proposed channel and access that were made. Given that these consultant reports are available the assessment should be expedited.

We cannot stress enough the importance of the Lake Manitoba Outlet Channel to the sustainability of our communities. This vital project must be completed to mitigate against future floods. The flood of 2011, again in 2014 and the near flood of 2017 indicates vulnerability. The enhancement of the Portage Diversion increases the capacity for inflow into the lake by approximately 6000 cubic feet per second above the 2011 rate. Lake Winnipegosis has seen historically high levels resulting in higher inflows into Lake Manitoba taxing the only existing egress at the Fairford Water Control System. Our concerns are well-founded.

We urge you to support the work done by two Provincial governments and encourage an expedited review by the Manitoba Clean Environment Commission in order that this vital project be completed by the fourth quarter of 2021, as announced.

Sincerely,

Jack King

President, Association of Lake Manitoba Stakeholders

St. Laurent, Manitoba

Lake Manitoba update: Feb. 4, 2018

It has been another week of gradual change. The level of Lake Manitoba has fallen to 811.92 feet, down 0.05 feet from last week. Outflows at Fairford rose slightly to 6,533 cfs while inflow from the Waterhen River fell to 2,649 cfs. The gauge on the Whitemud is malfunctioning but it is safe to say that it still at a trickle. Lake St. Martin fell this week to 802.05 feet. Lake Winnipegosis is lower this week to 832.25 feet. Flow on the Assiniboine is up slightly but still low, being 777 cfs at Holland and 805 cfs at Headingly. The Shellmouth Reservoir continues to drop and is now 1,395.73 feet.

Lake Manitoba update: Jan. 28, 2018

It has been a week of little change. The level of Lake Manitoba is down ever so slightly to 811.97 feet. Fairford flows declined to 6,498 cfs. Inflow from the Waterhen River also fell to 2,790 cfs. Flow on the Whitemud remains a trickle at 11 cfs. Lake St. Martin is up slightly to 802.11 feet. Lake Winnipegosis is slightly lower this week to 832.31 feet. Flow on the Assiniboine is up slightly, to 671 cfs at Holland and 719 cfs at Headingly. The Shellmouth Reservoir continues to drop and is now 1,395.87 feet.

Lake Manitoba update: Jan. 21, 2018

It has been a slow and steady week. The level of Lake Manitoba continues to fall and is now under 812.0 feet, sitting this morning at 811.98 feet. Fairford flows continue to fall and the current flow is 6,604 cfs. That is more than double the main inflow from the Waterhen River (2,843 cfs). Flow on the Whitemud remains very low at just 9 cfs. Lake St. Martin, however, continues to rise, and is now 802.09 feet. Lake Winnipegosis is slightly lower this week to 832.32 feet. The gauge at Holland on the Assiniboine was calibrated this week, and the flow readings now make more sense. Flow on the Assiniboine is low, being 625 cfs at Holland and 657 cfs at Headingly. The Shellmouth Reservoir continues to drop and is now 1,396.16 feet.

Lake Manitoba update: Jan. 14, 2018

Most of the gauges were calibrated this week so we have a much better picture of winter conditions on the lakes and rivers. The Westbourne gauge is back up after a long period out of service, and with it, we now have an estimate of Lake Manitoba’s level: 812.08 feet. Fairford flows continue to fall (as expected with growing ice): the current flow is 6,886 cfs. The gauge on the Waterhen River is now functional and it is flowing at 3,072 cfs. Flow on the Whitemud is just 5 cfs. This means that Lake Manitoba should continue to fall over the remainder of the winter. Lake St. Martin continues to rise, and is now sitting at 802.00 feet. Lake Winnipegosis is slightly higher this week to 832.37 feet. The gauge on the Assiniboine at Headingly was calibrated this week and is showing a flow of 646 cfs. The gauge at Holland remains ice affected. The Shellmouth Reservoir continues to drop and is now 1,396.52 feet.
