Fishing Lake St. Clair: what the data says
430-square-mile shallow basin between Lakes Huron and Erie; world-class smallmouth fishery. The lake tops out around 65 ft. The depth chart is built from real NOAA hydrographic survey soundings, so the humps, channels and drop-offs you see are measured, not guessed. Below is the species-by-species picture, pulled from the same data the map uses.
Smallmouth Bass fishing at Lake St. Clair
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. By summer they slide out to 10 to 30 ft, and by winter most fish are in 20 to 45 ft. Sand bar rise (south) is the standout, a offshore hump at roughly 14 ft, rated prime for summer smallmouth bass. Best bite is early morning and the evening. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
