Very nice! That's beautiful country. So much beautiful country, so little time.
Only 4 fish? That's discouraging and I've been there a few times. You go to all that trouble and expense and sometimes (late in the season when the water warms up) the fishing just isn't that good especially along the shore line. The fish seek deeper colder water. Or sometimes the fish are feeding deeper and farther out.

Please take this only as a suggestion, as it is what we used to do and is not for everyone. In fact the fewer people who do it the better.
We started taking in light weight one man rafts for late summer fishing. (eventually we started taking them all the time) Back then they were a little bulky and weighed about 5 lbs. and only cost about $50. But since fishing was the whole purpose for going, it was well worth it. We would catch fish left and right in the middle, whereas we would catch few or none in the shallow warmer water along the edges.
We also found that you could easily access every inch of a lake from a raft. Without a raft, lots of shoreline is not fishable because of brush, rocks, etc. And you could do it with a lot less energy than trying to hike around a lake. We either fashioned our own paddles on site, or just paddled by hand most of the time. Those lakes aren't usually too big.
I couldn't find the exact raft I own (they probably don't make it anymore) but was able to find a few. I noticed they are a lot more expensive now, but they sure have gotten lighter and less bulky.

Don't get me wrong! Every minute you spend in the Wilderness is time well spent, and even if you don't have a fishing pole you're a lucky man!

Guns are like parachutes. If you need one and don't have one you probably will never need one again.
