The 2013 Great Flood: Actions to Mitigate, Manage, and Control Future Floods
A final copy of The 2013 Great Alberta Flood: Actions to Mitigate, Manage and Control Future Floods whitepaper has been released. This document consists of collaborative recommendations made by Canada’s leading water experts. The document has been evolving for over a month thanks to the received feedback from water experts and Albertans. This document was written as a collaborative teamwork to determine the recommended actions that should be taken to strategize for future flooding.
During the creation of this report, two draft versions were posted here with the request for public feedback. The response was excellent, leading to the creation of a separate feedback document titled The 2013 Great Alberta Flood: Actions to Mitigate, Manage and Control Future Floods Feedback Compendium which catelogues the feedback received.
We’d like to thank everyone who sent in feedback on the draft iteration when it was posed two weeks ago. Additional information about this document will be posted on the Alberta WaterSMART website as it arises.
If you didn’t get a chance to share your feedback or if you have additional thoughts after reading the final version of the whitepaper please do not hesitate to contact us, and like always please continue to check our news section for updates on what is happening around water in Alberta.
Brad Stelfox: Living at the River’s Edge
The 2013 flood of the Bow River basin has triggered a long-overdue conversation about the natural and man-made factors that caused or contributed to these types of events. Across society, people are now asking pointed questions that relate to mitigation, prevention, headwater management, overlapping landuses, floodplain infrastructure, climate change, and flood proofing.
The WaterSMART White Paper provides an excellent broad overview of the complexity of this watershed issue and makes clear that integrated solutions are required to meaningfully address this challenge. Appropriately, the WaterSMART report identifies that both engineering and landscape management approaches are required if watershed integrity of the Bow River basin is to be conserved and risk to infrastructure is to managed at an acceptable level.
As a resident of the Sunnyside community in Calgary, our neighborhood was extensively flooded and most families experienced serious damage to their basements, and in some cases, structural damage to their homes. In comparison to the residents of lower Benchlands, High River, and many other communities, we escaped relatively unscathed. In the aftermath of these events, we are told that those who have experienced flooding are expected to go through the emotions of anger, denial, depression and acceptance. For most affected by the flood, there is a basic need to understand what happened and what factors contributed to an event that so forcefully changed our lives. Over the next several months, more information will certainly come forward to help residents better understand the weather, landscape, and landuse dynamics that shaped this massive event, but a few thoughts are respectfully offered below to help put some of these dynamics into context.
Bill Wahl: Flood Recovery and/or Flood Prevention
The following is an open letter addressed to the citizens of Alberta, from Bill Wahl of Medicine Hat. The letter expresses how Mr. Wahl has been affected by floods, but also points out how water in Alberta is being managed and areas for improvement. Have a read and please continue to share your thoughts with us through Facebook, Twitter or Email. Thanks for sharing, Mr. Wahl!
An open letter to the Citizens of Alberta
Flood Recovery and/or Flood Prevention
My name is Bill Wahl and I am frustrated!!
Like others in Medicine Hat and Southern Alberta we live in proximity of the South Saskatchewan River [have for 40 years] and have been affected by flooding, all-be-it not this year due to the installation of a high tech backflow preventer after the 1995 flood. We are thankful to family and friends who helped us move out of our home and for better preparedness of disaster services.
The main reason for my frustration is that I always thought that the dams on the tributaries of the South Saskatchewan River were there in part to help us out during times of impending floods. The Alberta Government meetings after the ’95 flood reported that flooding was caused by a severe precipitation event that occurred in very close proximity to the Oldman River Dam. That and a combination of technical issues caused by washed out flow sensors, telephone communications and the short time from onset of precipitation to significant increases in inflow did not give dam operators sufficient time to spill water ahead of high water entering the dam. Although dam safety was never an issue, water was released from the dam at a rate no greater then inflow. So what happened this year? According to records obtained from Alberta Environment and Sustainable Resource Development, the 2013 peak was ~5590 cm3/s and the 1995 peak was ~4200 cm3/s. The gauging station reports of the 2013 peak was more than 1m higher than 1995. The cross section of the river valley at other locations will affect this value to some extent. Levels in Medicine Hat never reached those predicted with an increase of 50 cm3/s increase in flow rate over 1995 reported. Persons who experienced the 1995 levels commented on water levels about 20 cm higher; all this being enough to cause significantly damage in Medicine Hat. How is it that the dam[s] that impact our flow rate could not have done more to mitigate flood issues this year given the knowledge gained from the ’95 flood, and new technologies for weather forecasting? We have experienced more floods in the past 20 years than the first 20 years of living by the river.
Keep Them Out Of The Floodways by Don Barnett
The following is a speech given by Don Barnett to the Inland Waters Directorate of Environment Canada in 1976. Don Barnett was mayor of Rapid City, South Dakota during one of the worst floods in South Dakota's history and at the time of this speech one of the worst floods in U.S. history.
We hope that the speech below will stir some thoughts from you, our readers, on how to mitigate floods in the future in Southern Alberta.
Join Our Discussion: How can Alberta prevent future flooding?
The rain may have stopped, but flooding in Alberta is not over. We're continuing the conversation on the Alberta WaterPortal and wanting to hear what you think. The below excerpt outlines five actions that were recently developed by leading Canadian water experts, to address future flood mitigation. What are your ideas? Join the conversation on Facebook, Twitter or email us.
Southern Alberta has just experienced the worst flooding disaster in the province’s history. At the Canadian Water Summit, held on June 27, 2013 in Calgary, a group of leading water experts were asked the question: “What can we do to mitigate these flood situations in the future?" These experts put forth five actions that all levels of government should consider today to avoid the impacts of similar flood events in the future.
- Anticipate more extreme weather events and plan for them.
- Improve our operational predictive capacity through better modeling and data management.
- Invest in infrastructure such as on and off stream storage, diversions, and natural storage such as wetlands.
- Consider flood risks in municipal planning, including building in flood plains, and better engineering of electrical, mechanical and back-up systems.
- Manage our water resources collaboratively, following the example of the Bow River Consortium, and ensure proper funding for the watershed planning and advisory councils across the Province.
Above all, leadership is vital. The intention is to have these recommendations reviewed and expanded on by a broad audience, and then presented to all levels of government for their consideration.
The Alberta WaterPortal is the vehicle for collecting input broadly, and for generating the dialogue that will shape these recommendations into significant action plans. Now, it's your turn. Share your ideas with us through Facebook, Twitter or email us!
