Rock Lake in Frontenac County: How and When to Fish It

• Overview

  Rock Lake is one of the Frontenac County waters in Ontario. The ground round it is mixed forest. At 3 hectares it is the sort of place you fish for an evening rather than a day. It is a small entry by Frontenac County standards. Sharbot Lake lies 31 km from the water. The nearest city of size is Kingston, 93 km away. There is no boundary nearby to worry about.

• Where to Fish on Rock Lake

  Depth figures are not published for this one. Where the bottom changes texture, fish gather; find that line. Bays and points beat straight shoreline every time on water like this. Survey and observation records for Frontenac County include pumpkinseed, bluegill, rock bass, smallmouth bass and yellow perch. County records show the wider picture rather than this one place. Read Rock Lake for ten minutes before the first cast goes out.

• Seasonal Patterns

  Climate records put July near 19°C and January near -11°C. The year runs cold to warm and back, with clear transitions. After late April the shallows warm and the fish move up. Averages suggest open water from about late April through to roughly early December. The open run goes from the thaw to the freeze, and April through October covers most of it. Plan any trip to Rock Lake around it.

• Tackle & Baits

  Whether the bank is open is not something our records settle. Nothing is listed nearby for parking or launching a boat. A small crankbait along the drop and a worm in the thick stuff cover the bass. Take the rules with you rather than trusting memory. A polite question at the farm gate opens more banks than anything else. Heart Lake, 1.3 km away, makes the obvious fallback. Where Rock Lake is concerned, a local answer beats a written one.
