SPN-8 DUG AT GAGE STRENGTH · THE FULL SEQUENCE STANDS IN THE MAJOR-EVENTS ADDENDUM
The Story of Walkerton section's flood beat is one sentence long because the town's flood story is one fact deep: Walkerton was built on drained marsh, and its water has been managed, ditch by ditch, ever since. Chapman saw the work mid-course in 1880 — the township's land "marshy and wet, but fast being reclaimed by draining" — and the federal gage record downstream dates the basin's extremes: the great floods of 1883 and 1887, carried by the U.S. Geological Survey as outside-record events, and March 1982 as the modern benchmark at the Davis gage nearest the town. The full sequence, with the Campbell-1882 divergence banked as a delta candidate, stands in the major-events addendum of this wave; the beat prints here so the Story of Walkerton section's telling and the events leg's telling are one story at two depths, not two stories.
