Marquardts Lake in Lennox and Addington County: How and When to Fish It

• Overview

  Marquardts Lake is a Lennox and Addington County water, Ontario side. It stands 413 metres above sea level. Surface area runs to about 8 hectares — small enough to read in one session. Bancroft at 47 km is the nearest place to stop. It is 115 km to Kingston, the nearest city. The nearest boundary is well away, so one set of rules covers the water.

• Where to Fish on Marquardts Lake

  The records we hold are silent on depth, so plan to find it yourself. Look for the band where the shallows give up and the bottom falls away. Still water like this holds fish on the edges rather than out in the open. Survey and observation records for Lennox and Addington County include pumpkinseed, rock bass, smallmouth bass and bluegill. At least one recorded species is protected in parts of its range; read the local rules before targeting anything. On Marquardts Lake that means starting tight and working out.

• Seasonal Patterns

  On the long-term average, July reads 18°C and January reads -12°C. Expect a real winter and a strong spring after it. Winter fishing happens on the ice here, with open water back around late April. Climate averages put the opening at about late April and the closing near early December. The weeks after the thaw and the ones before the freeze are the strongest. It sets the rhythm of the year at Marquardts Lake.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Sort the permit out before you load the car. A polite question at the farm gate opens more banks than anything else. Flake Lake sits 1 km off and takes the overflow. Check the position at Marquardts Lake before loading the car.
