Rain on and off through the day, with a soft N wind and steady pressure. Whatever swims in Upper Rock Lake should be near structure within a cast of the bank. The evening should out-fish the rest of the day. Take the steady approach over the searching one. The autumn feed-up is on; baitfish areas are the key.

Set in Frontenac County, Upper Rock Lake is an Ontario water. It sits in lake country bush. The outline measures near 7.0 km, so local knowledge counts. Size puts it in the front rank of our Frontenac County list. Nearest place of any size is Elginburg/Silvers Corners/Shannons Corners, 21 km away. Kingston sits 30 km out, and it is the nearest city worth the name. This one sits near enough to a boundary to be worth checking.
We hold no depth figure for this one. The shallow end warms first and pulls fish in ahead of the rest. The productive water is a rod length or two out, not a hundred. County-wide records name pumpkinseed, bluegill, rock bass, smallmouth bass and yellow perch. These are county-wide records, so not all of them will be in this water. On Upper Rock Lake the first feature you find is usually worth a session.
Seasonal averages run from -9°C in January up to 20°C in July. Hard water is a season in its own right here. After mid April the shallows warm and the fish move up. Ice usually gives way near mid April, and forms again about mid December. September and October fish steadily right up to the freeze. That is the shape of the year on Upper Rock Lake.
Whether you may fish here is not something records settle. This is a natural basin, not a dammed one. Parking sits 1.1 km out, which makes for a walk with tackle. A small crankbait along the drop and a worm in the thick stuff cover the bass. Some banks are open only from a marked point. Access can change hands, so last year's answer may not hold. Failing this one, try Stonehouse Lake, 1.4 km away. For Upper Rock Lake in particular, ask before you travel.
