How this water changes through the year
Over 22 years of record, flow on Gallatin River peaks in June, when the median runs about 2,820 ft³/s, and falls to its lowest in August at around 363 ft³/s. Today's 605 sits between the two. The band on the chart is where the middle 60% of years fall, so a reading inside it is ordinary for the date and one outside it is not.
