Mystery Lake is one of the lakes mapped in Marathon County and the published measurements are about 11 acres and a maximum depth of 8 feet, so you know roughly what you are getting into before loading the boat or walking the bank.

I would start with a few obvious areas and make the lake prove I need more with the first real effort focused on the best bank cover, any obvious weeds, and the deepest water I can reach before changing five things at once and losing track of what actually mattered.
Fish to think about
There is not a strong enough fish record for Mystery Lake to build a species-specific plan; that keeps the page honest, even if it means there is less to say right now, and and see which part of the list actually shows up that day.
Where I would put my time
For the opening trip to Mystery Lake, I would fish what is in front of me instead of trying to make the lake match an old report, and I would pull up the current Wisconsin fishing regulations before leaving home.
