Welcome to IDO…
I have fished Spider for a number of years as we have a cabin on a small lake nearby. Its a great muskie lake, however, just like any lake they seem to avoid my lures. I would say typical mid summer patterns would hold true for spider as well. Cabbage weedlines come to mind, possible deep rock humps/shelf, or long points extending into deeper water. If you have some time, might be worth while to buzz around the some of main basin to look for pods of bait fish. I would imagine the ski’s are hanging around with the cisco or tulipee in the lake. Crappies I have no idea where to start, but I would imagine suspended over deeper water as well. Enjoy the trip to spider lake, truly a pristine god’s country area, report back on your adventure.
