Do smallmouth move shallow and deep within a single day?
Yes, some fish change depth within a day, while others stay around a useful feature. Light, prey movement, current and available shelter influence the choice. A sunny clear calm period can favour deeper water or tighter rock/weed cover; cloud and chop can extend shallow use. A closed swim bladder does not lock every fish to one contour.
