TWDB estimated daily averages, reported as provisional. Storage is derived from source rating curves or supplied by the operator; total and conservation storage are different quantities. Percent full uses the capacity reported for that day. Source estimates may include upstream interpolation. Water Around adds no interpolation. Datum and capacity changes can affect comparisons; these are water-quantity records, not tests of drinking-water safety. Source note: Data from 2026-04-15 05:00:00 to 2026-09-26 04:45:00 is marked as provisional by the USGS.
