I cited two studies. One that was done by the Université du Québec à Montréal shows how waves cause erosion when people engage in sports that generate oversized waves less than 300 metres from shore. We should rely on that type of study to establish standards. That's what the State of Vermont has done. It has established standards based on studies conducted in Quebec. They are standards based on sports that generate oversized waves. We need to ensure that those sports are engaged in far from shore in deeper areas.
The maximum depth in our area, in Lac Memphrémagog, is 107 metres. So there are obviously areas where those sports really cause less damage. Engaging in that kind of sport in the middle of a large body of water such as ours is therefore not a problem, but doing so in shallow bays increases the risk.
