Are you boating? There are 2 launches on Lower Lake, the upper launch on Bear Wallow Rd (cabins) is the shallow side. If you launch from there hit up the pads just off to the right of the launch. I used to get monster gills in front of the pads on poppers. Most of that end is weed choked. If you head toward the channel it gets deeper and I've caught smallmouth bass through there. The dam side of Lower Lake gets to about 20 feet deep toward the dam off the lower launch which is where most of the trout hang out, if there are any left, they are stockies. Crappies could be anywhere right now, you will have to explore to find them, maybe try some night fishing. The Upper Lake is loaded with pickerel and also weedy, you won't find much depth over 8 feet if that. You should have a blast. It will most likely be crowded though. Good Luck and take some pics.
