The Grand Splash Week is a series of festive events taking place this summer, from July 1-10th, on the shores of various waterways in Quebec. Citizens are invited to take to the water at safe locations that are not public beaches, but have everything it takes to become one.

A Grand Splash,



It's an opportunity to have fun and take concrete action. Positive energy, smiles and joy are the order of the day!


The Grand Splash Week brings citizens together with a common goal: to democratize access to water!


The event aspires toward a Quebec society where everyone can fully enjoy the waterways, while respecting nature.


The Grand Splash Week is an initiative of Fondation Rivières, an organization that works to preserve, restore and enhance the natural character of rivers. The foundation contributes to ensuring water quality and access to water for the population of Quebec.

Honorary Chairmanship 2022


Clay and Friends has been thrilling crowds over the past few years with their electrifying rhythms and over-the-top performances. The group offers a percussive mix of hip-hop, soul and funk backed by the prose of what is now known as La Musica Popular De Verdun. His new album AGUA EXTEND'EAU is a real pleasure for the ears.

The concept of the Grand Splash was born in Quebec City in 1994. When the Société des Gens de Baignade took to the water, they demanded a public swimming site at the Bassin Louise. This inspired the creation of a Grand Splash in Montreal in 2003. This project brought together a few participants in the Old Port to demand swimming access. It was the citizen committee Montréal Baignade that led the initiative, supported by the organization Jour de la Terre.

In 2018, Fondation Rivières joined the adventure to organize the Grand Splash. They became the main organizer the following year. In 2020, the pandemic pushed the organizers of the Grand Splash of Montreal to rethink their formula, in order to maintain the course of the event's claims, despite the health measures in place. The "Petit Splash deviendra Grand" contest was therefore launched. This virtual edition highlighted potential swimming sites throughout Quebec.

This led to the creation of the Grand Splash Week in 2021, which attracted more than 300 participants in 10 municipalities across Quebec: Montreal, Quebec City, Lachine, Trois-Rivières, Saguenay, Gracefield, Sainte-Martine, Saint-Paul-de-l'Ile-aux-Noix, Saint-Jérôme and Mont-Saint-Hilaire, in addition to two mini-splash events held in Chambly and at the Promenade Bellerive park in Montreal's Tétreauville district.


The Grand Splash Week is making a real difference!

Here is the proof:

Grand Splash in Quebec City : a pilot swimming project in the Bassin Louise starting in 2022!

Grand Splash in Lachine, Montréal : announcement made regarding the City's intention to develop a swimming area at the new Lachine Waterfront Park.

Grand Splash in Saint-Jérôme : granting of a mandate to Fondation Rivières for contamination source tracking in the Rivière du Nord, in anticipation of allowing swimming in downtown Saint-Jérôme

Grand Splash in Sainte-Martine : federation of all the municipalities along the Châteauguay River to entrust Fondation Rivières with a contamination source tracking study to evaluate the swimming potential along 55 km of the river.

Mini-splash at the Parc de la Promenade Bellerive : commitment in the summer of 2021 by the Mayor of Montreal to open a swimming area in the St. Lawrence River in the coming years.
