is it the Orchid lake at Lacs Du Verger that your going to ?
If so, go on You Tube and search Lacs Du Verger, theres a few vids of some big fish caught from there.
They have either poissen chat or crays in there so they advise using there own Rosehip boilies as they dont seem to like those.
The Las Du Verger website do weekly catch reports as well, last week in the snow 30 odd fish came out to 8 anglers including a few 40s so you can only imagine how it fishes during the warmer months !!
