Stay clear and stay safe this Victoria Day long weekend

Spring rain and snowmelt mean faster flows on many waterways

Toronto - Ontario Power Generation (OPG) is reminding the public to stay clear of dams and hydro stations on Victoria Day weekend. Many parts of the province have experienced higher water levels and faster flows because of significant rain and snow melt this spring.

“Water levels on many lakes and rivers are much higher than normal. Please enjoy this Victoria Day Long Weekend, but remember to stay clear and stay safe around OPG’s dams and generating stations.”

Mike Martelli, OPG President of Renewable Generation

Water levels can change quickly. OPG continuously adjusts the flow of water through its dams to accommodate changing water conditions. These adjustments are coordinated with the relevant river authority.

Safety booms may also be damaged from unprecedented high flows and debris on the Ottawa and Madawaska Rivers. Residents should remain extra vigilant and watch for signage indicating dangers ahead.

OPG operates 66 hydroelectric stations and 241 dams on 24 river systems throughout Ontario.

For more water safety information, please visit www.opg.com/watersafety.

OPG is one of the most diverse electricity generators in North America. It produces about half of the electricity Ontarians rely on every day, and its clean, safe, power costs an average of 40% less than other generators.

Fin de semaine de la fête de la reine : plus loin, c’est plus sûr

La pluie printanière et la fonte des neiges augmentent le débit sur plans d’eau

Toronto – Ontario Power Generation (OPG) rappelle au public de se tenir à l’écart des barrages et des centrales hydroélectriques pendant la fin de semaine de la fête de la Reine. De nombreuses régions de la province ont été témoin ce printemps de hauts niveaux d’eau et de débits accélérés, à la suite de pluies abondantes et de la fonte des grandes quantités de neige.

« Les niveaux d’eau sur un grand nombre de lacs et rivières sont beaucoup plus élevés que la normale », a souligné Mike Martelli, président, Production d’énergie renouvelable pour OPG. « Profitez pleinement de la longue fin de semaine de la fête de la Reine, mais rappelez-vous d’être prudents et de vous tenir loin des barrages et des centrales ».

Les niveaux d’eau peuvent changer rapidement. OPG ajuste continuellement le débit à la sortie de ses barrages pour s’adapter aux conditions hydriques changeantes. Ces ajustements sont coordonnés de concert avec l’autorité responsable de la gestion des rivières pertinente.

OPG exploite 66 centrales hydroélectriques et 241 barrages sur 24 rivières en Ontario.

Pour obtenir plus de renseignements sur la sécurité et l’eau, veuillez consulter le site www.opg.com/watersafety (en anglais).

OPG est l’un des producteurs d’électricité les plus diversifiés en Amérique du Nord. Il produit environ la moitié de l’électricité pour satisfaire les besoins quotidiens des Ontariens et le coût de son énergie sûre et propre est en moyenne 40 % moins élevé que celui des autres producteurs.
