Brennan Lake Fishing near Petawawa, Ontario

A shoreline of some 2.9 km keeps the choices simple. It is low-lying compared with other Ontario water we list. The town to know is Petawawa, 2.7 km out. Further out sit Chalk River (16 km) and Pembroke (18 km). The county edge is within a short distance of the bank.

• Where to Fish on Brennan 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. Weed, then depth: that is the order to fish a water of this kind. Renfrew County records list smallmouth bass, pumpkinseed and yellow perch among the fish reported. Species recorded across the county may be limited to a few waters. At Brennan Lake the water rewards a slow, careful approach.

• Seasonal Patterns

  Averages here run 19°C at the top of summer and -13°C at the bottom of winter. Expect a real winter and a strong spring after it. The open season starts with the thaw, near enough late April. Open water usually runs from late April until about early December. Late spring and early autumn carry the year between them. Brennan Lake runs to its own calendar within the local pattern.

• Tackle & Baits

  Nothing on record says whether the bank is open or closed. Records list it as a natural water body rather than an impoundment. Public data has parking about 290 m from the shore. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Bank access can be seasonal on ground like this. Some water is controlled locally without a sign saying so. If the gate is shut, Jorgens Lake at 2.2 km is the nearest alternative. Treat access at Brennan Lake as something to verify.
