Largemouth Bass
Largemouth own the weedy east end of Guelph Lake — the shallow, weed-choked back bays and vegetated river-arm flats off Wellington Rd 124, opposite the harder dam-basin water the smallmouth work. This warm, stained reservoir with extensive shallow weed cover is a textbook largemouth fit, and the species ranks among the top three most-reported on the lake (Fishbrain: 123 anglers).

Largemouth hold in the shallow, weed-choked water of the back bays and river-arm flats, concentrated toward the warmer eastern portion of the lake. Fish the vegetated flats and bay edges through the open-water season, spring through fall — spinnerbaits and crankbaits worked over the mid-water weeds take both largemouth and the pike that share this cover.
Bass season opens the fourth Saturday in June, after the late-May-to-June spawn in the shallow warm bays. The reservoir's autumn drawdown pulls water off the weedy shallows late in the season, so the flats you fished in summer read lower by fall.
The eastern arm is reached by carry-in off Wellington Rd 29 rather than the main conservation-area ramps.
Structure
Largemouth dominate the weedy back-bay water to the east of the lake; anglers report fishing "a very weedy bay," with spinnerbaits and crankbaits producing mid-water bass and pike over the weeds.
