Has anyone here fished up on Gouin Reservoir in Quebec? Just saw that Navionics has partnered up with the management team up there to update the sonar charts. Pretty cool that you might be able to go to a fairly remote location like this and have 1 foot contours showing on your Navionics mapping chip!
