We email once when a fresh USGS reading crosses your line. If it's already past the line, we wait for it to come back and cross. After an alert we stay quiet until the reading moves back past the line by a small margin. Ice, missing, seasonal, or 6-hour-old readings don't count. Provisional readings are labeled in the email.
