Jeffreys Lake Fishing near Cobden, Ontario

• Overview

  The Renfrew County entry here is Jeffreys Lake, in Ontario. It sits at 150 metres above sea level. It runs to roughly 49 hectares — big enough to hold fish away from the bank, small enough to learn. The whole outline is near 4.1 km, and most of it is walkable. On our Renfrew County list it sits near the top for size. Some 10 km away sits Cobden, the nearest settlement. Renfrew follows at 15 km, then Shawville at 23 km. The boundary is near enough that local access rules are worth double-checking.

• Where to Fish on Jeffreys Lake

  Nothing in our records gives a depth for this one. This is a lake, so the margins and the first drop matter most. Weed, then depth: that is the order to fish a water of this kind. Fish documented in Renfrew County include smallmouth bass, pumpkinseed, yellow perch, rock bass and brook trout. Records at this level tell you what is in the area. Jeffreys Lake gives up its fish to patience rather than distance.

• Seasonal Patterns

  Expect July to average close to 20°C, with January the cold end at about -13°C. Fishing here follows the temperature more than the calendar. Ice fishing carries the winter, and the water opens about mid April. Break-up near mid April, freeze-up near early December: that is the shape of an average year. The open run goes from the thaw to the freeze, and April through October covers most of it. On Jeffreys Lake the same rules apply, with local timing.

• Tackle & Baits

  Public sources are silent on who controls the bank. It formed naturally, so levels move with rainfall rather than with a gate. We find no slipway, car park or made path within a short radius, so treat access as rough. A small crankbait along the drop and a worm in the thick stuff cover the bass. Rules for this water may differ from the county norm. Check whether bait restrictions apply before you buy any. For a change of water, Pumphouse Lake is 0.9 km distant. The position on Jeffreys Lake is worth confirming on the day.
