Brennan Lake in Renfrew County: How and When to Fish It

• Overview

  In Ontario, Brennan Lake falls inside Renfrew County. The bank is 314 metres above sea level. This is a pocket water of some 3 hectares, and every part of it is reachable from the bank. On size it sits at the modest end of our Renfrew County list. 28 km away sits Renfrew, the nearest town. Nepean sits 90 km out, and it is the nearest city worth the name. No border sits close enough to matter.

• Where to Fish on Brennan Lake

  No chart reached our records; the first cast is your sounding. A natural lake fishes on cover, and cover here means weed and timber. Where the bottom changes texture, fish gather; find that line. Records held for Renfrew County cover smallmouth bass, pumpkinseed and yellow perch. Records at county level tell you what is around, not what is stocked here. Work Brennan Lake in sections rather than trying to cover it.

• Seasonal Patterns

  On the long-term average, July reads 19°C and January reads -12°C. Winter shuts things down for a spell, then spring reopens them fast. The lid usually goes in late April, which opens the strongest weeks of the year. Averages suggest open water from about late April through to roughly early December. Look to early summer and the first cool weeks of autumn. Anyone fishing Brennan Lake regularly works to that calendar.

• Tackle & Baits

  The rules here are undocumented as far as public sources go. There is no mapped parking or launch close by, which usually means walking in. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Some banks are open only from a marked point. Night access is frequently treated as a separate matter. The nearest alternative is Holmes Lake, 0.7 km out. Nothing here settles the position at Brennan Lake for certain.
