We did a Dive Against Debris in Parc Regional des îles de St-Tymothée.  We search around the boat ramp.  It is a very busy place.  A lot of people pass by there for their boats, paddleboard, kayak and so on.  We where expecting to find a lot of rubish, but to our happy surprise, the water was very clean.  It was nice to see that there is some clean water free of rubbish in some places.
