"Chironomids are one of the most diverse and abundant aquatic insects in productive stillwaters and a significant trout food source on Kamloops lakes, other interior regions of the province, and most stillwaters throughout the Western states." ~ Brian Chan
I didn't enjoy stillwater fly fishing until I was introduced to Chironomid fishing on Pass Lake (WA). When Tate and I first heard of Chironomid fishing we were already dedicated long rod casters. Niether of us see any use for a 9 foot fly rod. At that time we both owned 10ft - 4wt Loomis fly rods (unfortunately no longer made) which we used religiously for everything from 6" brookies to 22" searun cutthroat (and the occasional 25lb Chum when the Dollies weren't interested). So when we heard that guys were catching trout at Pass Lake with long rods, long leaders, and big Chironomids, we couldn't help but jump into the mix. That was 15 years ago.... I haven't been to Pass
Lake in four years or so but with Spring in full swing, I have disappearing strike indicators floating in my head. We usually start our 'mid fishing in early spring and continue through mid summer. Chironomid fishing is fairly simple. As the larve emerge from the lake bottom and shoot for the surface (or stay suspened at certain depths) the trout just inhale them. You may have to figure out what depth the fish are feeding, but the presentation of the fly consists of just sitting there below a strike indicator. I generally like to get my fly deep, so I tie them with heavy tungsten beads and start fishing within 12" of the lake bottom. If that doesn't work I relocate the fly to a shallower position until I find the feeding fish. The only other advice I have is if you are fishing from a drift boat bring two anchors.
The real master of Chironomid fishing and all stillwater techniques in general is Brian Chan. I would suggest checking out his website to get much better information (and spelling/grammar for that matter).

As spring temperatures rise, chironomid fishing can be very effective at Pass Lake.

Another one of our favorite lakes to fish using this technique is Hihium Lake near Kamloops, BC.
