It's basically prime time muskie now through the end of Sept, especially in the Kawarthas. I was out with a buddy last year and we put 8 in the boat and I raised a really nice fish earlier in the day. I went back with something completely different and she ate on the first cast. To me, seeing a fish is as good as catching one. That's half the battle. How warm was the water? At this time of year when the water is in the mid 70s, you can't reel too fast. Great time to burn bucktails and cover a lot of water. If I was fishing the Kawarthas, I'd be either looking for giant cabbage flats, or weeds that drop into deep water (weeds in 8-15ft, dropping into 20+) You'll get fish moving in and out of this cover daily. Also never be afraid to make a cast to the Canadian side of the boat (The deep side) One of the biggest muskies I've ever raised in the Kawarthas came doing exactly this.
Good job and keep on casting!!!
Also Crowman, Gagnons has 30% off St.Croix musky gear during the Muskie Odyssey. I got three rods this spring, with the discount I got my Premier glass/graphite trolling rod for free
