ElizabethG, Mykal and I are heading to Upper Farmers for a bit of an exploratory outing this evg. If anyone else is game, then we are meeting in the restaurant (poutine, burgers) parking lot at 2544 Rue Saint-Louis, Gatineau for 5:30.
The flows will likely be somewhere in between the two days mentioned here:

The water will likely be a little bit colder than at Champlain.
