The dark area is measured water; hatched days have no measurement in our archive. Gaps are never filled with estimates. The ▽ is the lowest day in the period. Recent years in particular may be incomplete; our archive does not yet contain every historical value visible at the sources. The red ▼ is today’s reading.
