Freshwater Fishing.
Upper Rideau Lake is a multi-species fishery on the Rideau Canal's summit pool — largemouth and smallmouth bass, lake trout, northern pike, walleye, yellow perch, and black crappie, with the Westport Municipal Harbour giving direct village launch access. The lake falls within Fisheries Management Zone 18, which covers the Rideau and Cataraqui watersheds across southeastern Ontario.
The brief.
A current Ontario fishing licence is required and conservation-licence rules apply for daily catch and possession limits. Bass season opens the third Saturday in June and runs through December 15 (sport licence S-6, conservation C-2).
Walleye fishing has two windows — January 1 to March 1 and second Saturday in May through December 31 — with a 40–50 cm slot limit (S-4, C-2). Lake trout open season runs the fourth Saturday in May through September 8 (S-2, C-1).
Some FMZ 18 lakes carry additional or year-round lake trout opportunities; check the regulation summary for the specific water. Launching is direct from the Westport Municipal Harbour at the western shore.
