A closed sky with even light today, with a stiffish breeze from the SSW and pressure sitting still. Activity on Harkness Lake should centre on reed fringes and open pockets. The numbers single out the night. Cover water early, then settle where the signs are. The season of moving fish: stay mobile and watch for bait.

Harkness Lake lies within the bounds of Parry Sound District, Ontario. The surroundings are rolling bush. It runs to roughly 12 hectares — big enough to hold fish away from the bank, small enough to learn. A shoreline of some 3.8 km keeps the choices simple. The town to know is South River, 17 km out. Then Powassan, 32 km, and Huntsville, 48 km. The nearest boundary is a fair way off.
There is no recorded depth, so work from what you can see. Read the surface for the wind lane, then fish the edge of it. The shallow end warms first and pulls fish in ahead of the rest. County-wide records name smallmouth bass, pumpkinseed, yellow perch, northern pike and rock bass. Records at county level tell you what is around, not what is stocked here. On Harkness Lake the quiet end is the one worth the extra effort.
Seasonal averages run from -12°C in January up to 18°C in July. Cold winters and warm summers give a wide working range. Count the season from break-up, usually late April. On average, late April opens the water and late November closes it again. The open run goes from the thaw to the freeze, and April through October covers most of it. Anyone fishing Harkness Lake regularly works to that calendar.
Nothing on record says whether the bank is open or closed. It formed naturally, so levels move with rainfall rather than with a gate. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Check locally before you travel, because a wasted drive is a long one. Barbless rules turn up on managed water more often than not. Bluesky Lake sits 1.8 km off and takes the overflow. Rules at Harkness Lake are worth checking on the day.
