Flower Round Lake in Lanark County: How and When to Fish It

• Overview

  The Lanark County end of Ontario holds Flower Round Lake. It lies 187 metres above sea level. About 1.02 sq km, so local knowledge or a boat saves a lot of walking. The perimeter runs near 5.9 km, so plan the walk before you start. On our Lanark County list it sits near the top for size. The closest town, Renfrew, is 33 km away. Mississippi Mills follows at 39 km, then Almonte at 39 km. A county boundary sits nearby, which can matter for local access rules.

• Where to Fish on Flower Round Lake

  No chart reached our records; the first cast is your sounding. Where the bottom changes texture, fish gather; find that line. A natural lake fishes on cover, and cover here means weed and timber. Species logged across Lanark County include pumpkinseed, rock bass, smallmouth bass and bluegill. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. The shape of Flower Round Lake rewards a slow walk along one bank.

• Seasonal Patterns

  Expect July to average close to 19°C, with January the cold end at about -11°C. The year splits cleanly: hard water, then open water. Winter fishing happens on the ice here, with open water back around mid April. The open-water window runs from around mid April to about early December in an average year. Late spring and early autumn carry the year between them. Plan any trip to Flower Round Lake around it.

• Tackle & Baits

  Public data does not answer the access question here. It formed naturally, so levels move with rainfall rather than with a gate. There is a mapped slipway roughly 900 m away. A small crankbait along the drop and a worm in the thick stuff cover the bass. Check whether a boat is allowed before you tow one. Barbless rules turn up on managed water more often than not. Failing this one, try Bartraw Lake, 2 km away. Ask locally about Flower Round Lake if anything is unclear.
