ADWR Annual Water Usage Report

Start reading = the base record opening 2026, end reading = the base record opening 2027 — usage is one subtracted from the other. Base records are the turn-of-year readings flagged by the crew (marked ★), normally taken Jan–Mar, sometimes early in the preceding December. Where a well-year was never flagged, the reading nearest Jan 1 is used instead and the row is marked ≈. Acre-feet = cumulative running total at end record − cumulative running total at start record. Meter resets and replacements are handled automatically. Check Done as you manually enter each well into the ADWR portal.
