Fishing smallmouth bass around St. Thomas
The waters around St. Thomas give smallmouth bass anglers real options: 1360 documented waters in range are on record for smallmouth bass in our Ontario catalogue, and their daily scores - built from weather, water temperature at depth and species-fit modelling - decide the order shown above rather than reputation or hearsay.
There is a spread worth reading in today's leaders. Grand River sets the pace at 77 (about 111 km from St. Thomas), while Spencer Creek sits at 77 (about 114 km from St. Thomas). Thames River (rivière Thames) holds third at 77. Those gaps are real information: the same smallmouth bass conditions rarely land evenly across different depths, sizes and shorelines.
Smallmouth relate strongly to hard structure - rock, gravel, and boulder shorelines, rather than the heavy vegetation largemouth favor - and pound-for-pound are widely considered among the hardest-fighting freshwater fish, with acrobatic jumps that test light tackle. Ontario smallmouth concentrate on the rock-and-rubble structure Canadian Shield lakes are known for - rocky points, islands, offshore humps and boulder reefs, often in strikingly clear water. Local anglers lean on tube jigs and 3-4 inch soft plastics in crayfish colours worked slowly along rocky bottom, switching to jerkbaits and pause-heavy topwater lures around low light. Bass season in most southern Ontario zones opens the third Saturday in June and runs into late fall, with exact dates and any catch-and-release windows varying by Fisheries Management Zone.
These scores are not season-long ratings. They are rebuilt every morning from fresh weather and water-temperature data, most recently for September 14, 2026, so the best smallmouth bass water near St. Thomas this week may not be the best one next week.
