If you happen to go through Trout Lake on the way up there, stop at the ranger station. They have a free flyer of several pages called "Lakes and Waterfalls" It has a map and lists all the lakes in the area,size,elev.,species,location,access rds,regs-motors/electric only, etc. Good info.
Takalak (I can't spell this one) lake is excellent for small brookies, this lake has the very best view of any lake I have ever been too, truly beautiful. Ollalie has some nice browns and cut throat, and Council (if you have a tube) is excellent for cut throat. The one lake I have yet to try, but hear is real good for big browns, is Horseshoe lake.
This is what has worked great for me in the past.
Takalak = size 14 gnat, mosquito, or adams.
Ollalie = good ole worm.
Council = Black wooly bugger on sinking line.
Good luck and post a report when you get back, I'd like to head up there about the middle of august.
