Just to let you guys know a little about these lakes, now I am no expert here , but I started fishing trillium in the early 70,s and I first fished Harriet in 64 when I WAS 14 years old .
PGE AT the time had a lodge or something built over the front part of the lake,we use to go up there and stay on weekend over niter with the youth group I was in but in the 70.s they tor it down, that is why you see the stump like things in the upper part of the lake, these were the foundations for the lodge.
Now it can be a tricky lake to fish, I have a theory now it i just a theory, But when they first stock these lake , especially when they have snow water coming in them, the lakes are abnormally cold, when the planters and the trophy size trout are raised in a little warmer water. and so when they are induced in these cold mountain lakes this time of year it shocks the fish system and they stay dormet for a short period. and from what I have seen they perk up when the water temp rises a little or when there is a first rain. because I have been up there right after the truck dumped in and for approx 3 days ,not a nibble, then when things change BAM!..this happen to me on time in Harriet we got skunked big time and we seen fish rolling and splashing all over so we noticed a weather system coming in , and we got up there right when it was a heavy over cast cloudy day....we were catching fish all over and just trolling a worm by itself or just casting and reeling in from a canoe.
In early to mid October we would fish the upper arm approx 300 yards up from where the drainage from Timothy comes in to Harriet with a bumble bee pattern "woolly worm"
and do very well on big Browns.
Now trillium is not as finicky you can just relax and catch fish in this lake with just about anything worm and bobber just drifting in a rubber raft or boat, but i like to try things different we kill them every time here with using a fluorescent pink and silver triple teaser. for some reason here that works great, we tried it in Benson lake and NOTHING!.... but when we tried the , what we call, the bumble bee pattern rooster tail, the ones with the yellow body and black dots, with dark hackle. we limit out every time in Benson lake , with them .
And then again if we use the bumble bee rooster tail in Trillium it is not that good, I found out last year that when i caught two , what you would call trophy size, in trillium I was using a small frog flatfish, this is a great set up when I fished Ollilie lake.
Now many of you probably have your own set up that works great, is some of thee lakes local lakes. But I have found out over the years when the lakes water temp warms up a tad, then fishing can be great, then in the dead of summer from mid July to end of august I only fish evening for trout or I am fishing washington for summer steel head.
