Flat light and a covered sky today, with a consistent blow out of the WSW with a settled glass. Activity on Rock Lake should centre on points where shallow meets deep. The evening carries the best of the day. Change depth before you change anything else. The season of moving fish: stay mobile and watch for bait.

Rock Lake is one of the Sudbury listings for Ontario. It sits in pine and birch. At 8 hectares it is the sort of place you fish for an evening rather than a day. There is roughly 11 km of bank, more than one visit can cover properly. Our Sudbury list holds plenty of bigger water. Some 56 km away sits Lively, the nearest settlement. Greater Sudbury is 59 km away, with Markstay-Warren at 64 km. One jurisdiction covers this water end to end.
Without a survey to go on, judge depth from how the bank falls away. The shallow end warms first and pulls fish in ahead of the rest. Weed, then depth: that is the order to fish a water of this kind. Across Sudbury, recorded fish include smallmouth bass, northern pike, yellow perch, Iowa darter and walleye. It is the county picture; the agency list is water-specific. On Rock Lake a short move beats a long cast.
Seasonal averages run from -10°C in January up to 19°C in July. The freeze arrives properly here and holds. Look for the thaw near mid April; the fishing lifts straight after. Climate averages put the opening at about mid April and the closing near early December. The weeks after the thaw and the ones before the freeze are the strongest. It holds true on Rock Lake more years than not.
Nothing on record says whether the bank is open or closed. Records list it as a natural water body rather than an impoundment. Formal access is not mapped, so the last stretch is likely on foot. A small crankbait along the drop and a worm in the thick stuff cover the bass. Rules differ from one water to the next round here. Barbless rules turn up on managed water more often than not. If the gate is shut, Bass Lake at 2.3 km is the nearest alternative. Ask locally about Rock Lake if anything is unclear.
