    The CDA will have their annual conference in Quebec city this fall. Les Amis is submitting a paper on the following topic:

    [b:2hjwnfte]navigation at control structures[/b:2hjwnfte]

    members of the Canadian Dam Association (CDA) are interested in the point of view of recreational paddlers on this issue.

    This is a key opportunity to communicate sustainable development concerns to this key group of stakeholders.

    They want a constructive presentation on “navigation through dams, spillway design, required clearances and design resources, dam and boom design, and water flows and safety issues…”

    Any amongst you with pictures, stories, viewpoints, personal experiences, please contact me at SUBJECT CDA CONTENT.

    Public Works and Government Services Canada (PWGSC) proponent of alterations to an existing Class B Dam at Laniel, Quebec has applied for approval under the Navigable Waters Protection Act. Located at the outflow from lake Kipawa and the start of this section of the Kipawa River this dam was originally constructed in 1910. Concerns for its age, structural integrity, and the need to increase the water release capacity at this location means that the project will proceed.

    A not-for-profit organization representing the commercial and recreational white water community, Les Amis de la Rivière Kipawa (LARK), is arguing that given the value of Kipawa river’s whitewater, PWGSC should not, unnecessarily, by design, impair navigable access to the river at the location of the new structure. In fact access to the river since 1968 has included, water levels permitting, navigating the open sluiceways of the Laniel flood control dam.

    The paper will discuss issues and relevance of multiple use potential of water control structures, as well as recreational navigation issues including: spillway design and required clearances; dam and boom design; water flows and safety issues; and finally joint management/users groups.

    Travaux publics et Services gouvernementaux Canada (TPSGC), initiateur d’un projet de reconstruction du barrage de Laniel, classé de catégorie B, a fait une demande de permis sous la Loi sur la protection des eaux navigables (LPEN). Localisé à la sortie du lac Kipawa et constituant le début du tronçon de la rivière du même nom, le barrage de Laniel a été construit au début des années 1910. Des déficiences en raison de l’âge de la structure, de son intégrité structural et les besoins d’augmenter la capacité d’évacuation de l’ouvrage font que le projet de reconstruction a été jugé nécessaire.

    Les Amis de la Rivière Kipawa (LARK), un organisme sans but lucratif souligne l’importance des zones d’eaux vives, telles que rencontrées sur la rivière Kipawa, comme outil de développement économique au Canada et à travers le monde. Selon LARK, TPSGC ne devrait pas, de par sa conception, limiter l’accès à la navigation au droit de la nouvelle structure. En fait, l’accès à la rivière depuis 1968 comprend, lorsque les niveaux d’eau le permettent, la navigation à travers l’ouvrage de Laniel.

    Cet article discute des enjeux et de la pertinence de maintenir un usage multiple aux ouvrages de contrôle et des enjeux reliés à la navigation tels : la conception d’un déversoir et les dégagements nécessaires; la conception d’estacades de sécurité ; les écoulement d’eau, les problèmes de sécurité, de même que la gestion conjointe avec les groupes d’intervenants.


    Navigation of water control structures occurs on various rivers in North America such as on the Achigan and Bonnybrook rivers in Quebec, the Moose River in New York, and the Gull River in Minden, Ontario where there is a Whitewater Preserve established. The dam on the Gull River owned by Parks Canada is part of the Trent/Severn waterway and gets run hundreds of times/week during the summer.

    Paddles of Ager’s falls on the Moose River in New York must sign a waiver prior to passing over the dam during the Moose River Paddling Festival. The AWA (American Whitewater Affiliation) has an agreement with the power company to provide 20 releases per year on the bottom Moose. Ten of the days are locked to specific Sundays with the remaining ten scheduled by AWA Bottom Moose coordinator. On the other hand, several people have been ticketed for running Fenelon Falls, Ontario, which involves coming within the 50m no boating zone for the dam just above the falls.
