“Time to start building an ark,” said the elderly man ahead of me at the Hort’s this morning. Surveying the current situation, he may be right.
Deluges of rain in the Souris River watershed over the weekend have already raised the river to dangerously high levels in Saskatchewan, where flash flooding has occurred, and North Dakota where the city of Minot has evacuated about 14,000 people. Twenty-six Saskatchewan communities have declared states of emergency due to flooding. That water now heads into Manitoba. Its first hot spot is the town of Melita, already heavily diked against the flow. These pictures I took on Tuesday show Melita’s current water levels.
Dikes around Melita will be bolstered against the new higher flows. Downstream the communities of Wawanesa and Souris are bracing for the new onslaught expected over the next three weeks. Existing dikes in Wawanesa will need come up eight feet to protect the town! The Souris River drains into the Assiniboine which will continue to be heavily diverted north into Lake Manitoba, exacerbating the flood problems around its shore. In the past couple of days, more evacuations have occurred around the lake in the RM of Siglunes, town of Alonsa and Lake Manitoba First Nations. Watch a short video of flooding at Lake Manitoba Narrows. At this time, 2,649 Manitobans are evacuated from their homes. These pictures show more of the devastation at Twin Lakes Beach.
The excessive rainfall has saturated the prairies. Total rainfall between April 1 to June 21 at many locations in Saskatchewan and Manitoba is approaching annual totals. For example, Weyburn, SK has received 82% of annual normal precipitation (342 mm), Melita 51 per cent (516 mm), Souris 65 per cent (518 mm) and Brandon 61 per cent (472 mm). It’s a sunny, muggy day in Manitoba today and similar in southeast Saskatchewan. However, more rain is ahead for the Souris River basin this weekend.
There are currently 31 states of local emergency (SoLE) and five prevention orders. Since the Manitoba Emergency Co-ordination Centre opened in early April for spring flooding, there have been 67 SoLEs and 31 prevention orders declared across the province by local authorities.
I took these next three pictures on Tuesday. My friend Chris surveys inundated Riverside Park, where the Souris River crosses Hwy #10 south of Brandon. The Souris River flows toward an old bridge next to the park then the view downstream.
The prairies remain vigilant for sudden flooding and unexpected rainfall amounts.
I am working on an update about Spruce Woods Provincial Park for posting over the next two days. Keep your powder dry.
Three Manitoba Flood Comments
I trawl select comment pages for accounts and background on the flood. Here are three comments from a CBC report about how much water the Portage Diversion added to Lake Manitoba, which continues to flood. I have no idea who made these statements, make no claim as to their veracity and present them as potential examples of how far ahead of the government Manitobans are and how deep the harm from man-made flooding has gone. Here’s the quote from the article.
“(Steve) Topping said extra flows from the diversion represented about three inches of water to Lake Manitoba.”
Comment #1
The “extra flows” are those in excess of 25,000 cfs. If you can calculate that, be honest with us now and tell us how much the entire diversion contributed over the full time of its operation and how much it continues to contribute, since it is still in operation. Please project how much more it will add. And don’t give us a wishy-washy “well, it’s hard to say because of the natural flows.” That’s untrue. It’s math. Calculate volume. To put things in perspective, tell us how much each river and the unnatural diversion individually contributed.
This is what many people along the lake, as well as those watching from across Manitoba, are wondering. Frankly, we know you made a mistake. You know it. Own up. Give us the facts. Telling the truth and giving information is the start to healing the people along the lake – though every storm is now going to rip open the wound caused by the use of Lake Manitoba as a storage facility.
Comment #2
Fairford River Flows:
8,400 cfs July 10 to Dec 1, 2010
5,600 cfs Dec 1, 2010 to mid-Feb 2011
9,100 cfs mid-Feb to mid-Apr 2011
Lake Manitoba level 812.66 at freeze-up, rose 4 inches to 812.99 at breakup. At the end of November last year someone made the decision to keep Lake Manitoba at or above regulated levels over the winter in order to prevent flooding downstream of the Fairford Dam. In retrospect this appears to have been a very poor decision.
Comment #3
Volume of water which has flowed down the Portage Diversion between April 6 and June 2 equals 2,355,000 acre-feet. Surface area of Lake Manitoba is approximately 1,152,000 acres. Divide the first number by the second to arrive at the increase in lake levels due to the diversion is 2.04 feet.
