Passing showers with dry spells between, with hardly a ripple anywhere and the barometer holding steady. Start the search at Mystery Lake along the margins and the shelf beyond them. The forecast backs the stretch from morning through afternoon. Ride the conditions while they last. Cooling water has fish active and on the move.

Mystery Lake belongs to Algoma, Ontario. The surface lies 458 metres up. Surface area is around 69 hectares, which gives you real water without needing a boat. Shoreline length is close to 8.9 km, and each section fishes a little differently. Compared with other Ontario water on our list, it sits high. The town to know is Sault Ste. Marie, 86 km out. Greater Sudbury is the closest city, 203 km away. The county line is nowhere near, so one local authority covers the water.
No published figure covers depth, so learn it as you fish. Look for the band where the shallows give up and the bottom falls away. This is a lake, so the margins and the first drop matter most. Records held for Algoma cover walleye, northern pike and Iowa darter. Species recorded across the county may be limited to a few waters. On Mystery Lake a short move beats a long cast.
Long-term averages put July at about 17°C and January near -14°C. The year splits cleanly: hard water, then open water. After late April the shallows warm and the fish move up. The season between ice runs from about late April to late November. Fishing peaks soon after break-up and again before the cold returns. Plan any trip to Mystery Lake around it.
Nothing we hold confirms whether access is permitted. No dam controls it, and the level follows the season. There is no recorded infrastructure here; expect to find your own way in. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Take the rules with you rather than trusting memory. Access can change hands, so last year's answer may not hold. For a change of water, Island Lake is 1.6 km distant. Treat Mystery Lake as unsettled until someone local tells you otherwise.
