Hi, welcome!
If you live near Bancroft you’re not too far from Silent Lake Provincial Park. A good spot to fish if you’re confined to shore or a nice place to use your SUP or kayak as it’s a non motor lake. I’ve only ever fished it briefly and caught small smallmouth but it’s my understanding that some decent trout fishing (and eating) is to be had. I’m assuming there’s probably alot of good lakes up your way; I’m just not very familiar with the area. Anyways, best of luck
