River levels are shown against their usual, but not yet judged. A gauge’s usual here is its range of October monthly averages; the reading is the latest 15-minute value, which a passing rain or dry spell can carry outside that range. So no river gauge makes this county Unusual For Here until we compare each day with the same day’s history.

A gauge’s usual is its range of October monthly averages over its record (USGS).
