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.”
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.
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.
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.
