Public Safety Around Dams and Site Tour

October 21 – 22, 2023 

Delta Winnipeg - Room: Assiniboine A

Includes breakfast, breaks and lunches

Includes half-day bus tour to St. Malo Dam

Fee: $625.00

A 2 day course, Dams and Public Safety, provides training on public safety risk assessment based on the methodologies presented in the Canadian Dam Association’s Guidelines for Public Safety Around Dams, 2011. This will deliver a practical hands-on workshop providing realistic case studies and tools that can immediately be applied for the assessment of public safety risks at a facility. 

Dam Safety Guidelines usually address the various hazards which can lead to the failure of a dam and present methods to manage these risks. However, more people have died in accidents around dam sites that are not associated with structural failure of dams. Use of water resources for recreation and other purposes means dam owners and operators are expected to manage their facilities to minimize risk to the general public. The Canadian Dam Association issued the Guidelines for Public Safety Around Dams and three associated Technical Bulletins in 2011. 
This Workshop provides training on public safety assessments based on the methodology presented in the Guidelines. 
•    Workshop attendance is limited to maximize the opportunity for participation 
•    Case studies addressed by small working groups 
•    Presentations made by CDA-trained instructors 
•    Extensive training binders and electronic resources are provided to each registrant 
•    Site visit in the second day to a local dam (St. Malo Dam) for a hands on site evaluation and demonstration of the techniques learned. 

Who should attend? Managers and operators of dam facilities, regulators and consultants who make risk management assessments or decisions relating to public safety. 

 

 

Dam Safety Review 

Saturday, October 21, 2023 - 8:30 am – 4:30 pm

Delta Winnipeg - Room: Assiniboine B

Includes breakfast, breaks and lunch

Fee: $495

Participants will develop an understanding of the following:

1. Dam Safety Review process as described in the CDA technical bulletin
2. Roles and expectations of the dam owner and review engineer
3. How a safety statement can be made and supported

Attendees will work through exercises to better understand how to scope a Dam Safety Review and learn what information is required to;

• assess the safety of a dam
• how to approach the hazard-failure mode-control aspect of a safety analysis,
• how to present the findings in a manner that supports decision-making by the dam owner

Printed course material is provided for attendees to use during the workshop and keep for future reference. Please note course materials do not include the Technical Bulletin. Tools and samples are also included. Exercises are completed in small groups, allowing for significant discussion and peer learning among workshop participants. The workshop is aimed at dam owners, consultants and regulators who want to gain a better understanding of good practice as described in the CDA’s Technical Bulletin: Dam Safety Reviews.

Workshop Objectives

The objectives of the workshop are:

1. Understand the expectations of a dam safety review consistent with guidance issued by the Canadian Dam Association including:
   • Provide an understanding of the Dam Safety Review process as outlined in CDA’s Technical Bulletin on Dam Safety Reviews
   • Provide an understanding of the roles and expectations of the Dam Owner and Review Engineer in a Dam Safety Review
   • Provide an understanding of how a safety statement can be made and supported
2. Provide a networking opportunity for dam professionals.

Exercises will be carried out to demonstrate a) the information required to assess the safety of a dam; b) a framework for considering hazards, failure modes, and controls; and c) the need for Dam Safety Review findings that support decision-making.
