Wet weather working through today, with dead-still conditions with the glass holding level. The productive water at Jonson Lake will be around the first drop-off and weed lines. Not a day the forecast likes; the morning keeps a flicker of interest. Fish the best hour hard and keep the rest short.

Jonson Lake falls in Sudbury, part of Ontario. The surface lies 377 metres up. With some 43 hectares of water, there is room for a boat but no need of one. With 5.5 km or so of shoreline, boat anglers cover ground the bank cannot. Nearest place of any size is Timmins, 98 km away. The nearest city of size is Greater Sudbury, 125 km away. No border sits close enough to matter.
We hold no depth figure for this one. Weed, then depth: that is the order to fish a water of this kind. A natural lake fishes on cover, and cover here means weed and timber. County-wide records name smallmouth bass, northern pike, yellow perch, Iowa darter and walleye. Take it as the county picture rather than a promise for this water. On Jonson Lake the first feature you find is usually worth a session.
In an average year July sits at 17°C and January at -16°C. The year splits cleanly: hard water, then open water. Hard cover is dependable here; it goes around late April. In an average year the thaw lands around late April and the freeze near mid November. The first weeks of open water and the last are the ones to plan for. That shapes the year on Jonson Lake.
Our records carry no access rule either way. No dam controls it, and the level follows the season. No launch point is recorded nearby, so this is a bank water unless you carry a boat in. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. A phone call first saves an afternoon. Barbless rules turn up on managed water more often than not. Should this one be busy, Oddur Lake is 0.7 km off. Check the position at Jonson Lake before loading the car.
