Mellon Lake Fishing in Lennox and Addington County, Ontario

• Overview

  Mellon Lake sits in Lennox and Addington County, out in Ontario. The setting is pine and birch. Roughly 1.37 sq km of surface: treat each bay as a water in its own right. With 22 km or so of shoreline, boat anglers cover ground the bank cannot. It ranks high for size among our Lennox and Addington County listings. Tweed lies 20 km from the water. Madoc lies 31 km off, Greater Napanee another 37 km. A county boundary sits nearby, which can matter for local access rules.

• Where to Fish on Mellon Lake

  Depth went unrecorded, which puts the reading back on you. Read the surface for the wind lane, then fish the edge of it. The shallow end warms first and pulls fish in ahead of the rest. Lennox and Addington County records list pumpkinseed, rock bass, smallmouth bass and bluegill among the fish reported. Some of the species recorded here are protected or tightly regulated, so check what may be targeted before you fish. Anyone new to Mellon Lake should walk it once before setting up.

• Seasonal Patterns

  Average temperature peaks around 20°C in July and bottoms out near -10°C in January. The year splits cleanly: hard water, then open water. Look for the thaw near mid April; the fishing lifts straight after. On average, mid April opens the water and early December closes it again. The open run goes from the thaw to the freeze, and April through October covers most of it. Plan any trip to Mellon Lake around it.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. No dam controls it, and the level follows the season. Nothing in the way of made access shows up nearby: no ramp, no car park, no path. A small crankbait along the drop and a worm in the thick stuff cover the bass. A phone call first saves an afternoon. Where parking is tight, arriving early solves most problems. The nearest alternative is Palmeteer Lake, 2.1 km out. Treat Mellon Lake as unsettled until someone local tells you otherwise.
