Round Island Lake in Nipissing District: How and When to Fish It

• Overview

  Nipissing District, Ontario, is where Round Island Lake sits. It sits at 434 metres above sea level. It measures some 1.68 sq km, and wind has room to build across it. The edge covers about 12 km, enough to hold several distinct areas. Size puts it in the front rank of our Nipissing District list. Chalk River is 66 km and Deep River 68 km. No border sits close enough to matter.

• Where to Fish on Round Island Lake

  No depth figure appears in our records, so the bank has to tell you. This is a lake, so the margins and the first drop matter most. A natural lake fishes on cover, and cover here means weed and timber. Nipissing District records list smallmouth bass, cisco, yellow perch, pumpkinseed and rock bass among the fish reported. Records at county level tell you what is around, not what is stocked here. Read Round Island Lake before you fish it and the day goes better.

• Seasonal Patterns

  Typical July readings run about 18°C; by January the average is down near -13°C. The year splits cleanly: hard water, then open water. Break-up comes around late April, and the run that follows is short and strong. Going by climate averages, expect open water from about late April until roughly late November. The weeks after the thaw and the ones before the freeze are the strongest. That shapes the year on Round Island Lake.

• Tackle & Baits

  Access is not recorded for this water. Records list it as a natural water body rather than an impoundment. Overnight stays are possible about 250 m out, where camping is mapped. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Season dates differ by species, so read the table. Rules for boats are stricter than rules for the bank in many places. Should this one be busy, Mocking Lake is 1.4 km off. Check the current arrangement for Round Island Lake.
