How we know

  • 660lakes where an angler logged one in Fish ON-Line; on 265 of them a single trip, one angler’s report

Self-reported by anglers, not a Ministry survey. A lake that isn’t listed may still have them: a lake appears here only once an angler has logged this fish there.

Inland lakes on this list run from 4 to 221,497 acres (median 514) and from 5 to 408 ft deep (median 70 ft).

When and how anglers catch smallmouth bass

From 2,030 trip reports naming smallmouth bass on the lakes above, logged by anglers in Ontario’s Fish ON-Line app. These are self-reported trips, not a Ministry survey: they show when and how people fish for them, not how many fish a lake holds.

Trips by month

The busiest month is July (29% of trips); 3% were logged December–February (lighter bars).

How to recognize it

A bronze-green to olive bass with broken dark vertical bars on its sides and dark bars running back from the eye. The upper jaw does not reach past the eye, and the two dorsal fins look almost joined, with only a shallow notch.

Don’t confuse it with

Largemouth bass — Its upper jaw reaches past the eye, it has a dark stripe running lengthwise rather than vertical bars, and the notch between its dorsal fins is deep.
Rock bass — Much smaller, with a large red eye, rows of dark spots along the sides and six spines in the anal fin.

Up close

Illustration of a smallmouth bass's head and front half from the side, mouth closed, with the upper jaw ending below the eye, a shallow notch joining the two parts of the dorsal fin, and dark vertical bars on bronze-brown sides.
Smallmouth bass: the upper jaw ends below the eye, not past it; the dorsal fin is joined by a shallow notch; dark vertical bars on bronze-brown sides.
Illustration of a largemouth bass's head and front half from the side, mouth closed, with the upper jaw reaching past the back of the eye, a deep notch between the two parts of the dorsal fin, and a dark band along the side.
Largemouth bass: the upper jaw reaches past the back of the eye; the dorsal fin is almost split in two; a dark band runs along the side.

AI-generated close-ups, not photographs, drawn from the cited descriptions. They show what to look for; they are not a substitute for an expert identification (provenance).

Life in an Ontario lake

Smallmouth bass are a cool-water fish of clear lakes and rivers. In lakes they hold around rocky shorelines, points, offshore shoals and fallen trees, and move to deeper rocky structure later in the season; they are seldom found in thick weeds, which leaves those areas to largemouth bass. They are often found alongside rock bass.

Males build and guard nests in spring, usually in water less than about 3 m (10 ft) deep on sand or gravel near cover such as boulders or fallen trees. Growth is slow in Ontario, taking about six years to reach 30 cm (12 in), and fish can be stunted in small, crowded waters. The species is found across the Great Lakes watershed and St. Lawrence River and north past Lake Nipissing, with introduced populations in many northwestern lakes; it is absent from the far north.

Rules and eating

Before fishing, check the current Ontario Fishing Regulations Summary for your Fisheries Management Zone, any exceptions for the waterbody, and your licence type. Angler catch reports show what people logged, not what is legal to catch or keep. Fish ON-Line itself (how to use it) maps the zones and exceptions. Before eating fish from a particular lake, check the Guide to Eating Ontario Fish.
