Gross can be a very tough lake to fish, I've been going there for a long time but not this year yet. Its a very deep lake with steep dropoffs almost everywhere. Lots of rocks, if you are fishing deep or on the bottom you will lose a ton of lures for sure. I like to use spoons there and try different depths while moving around to differt spots a lot. Some of the coves can be good for trout if the main lake isn't fishing well.
Good luck, its a nice lake but most of the fish are on the small side.
