  • La Plata fell 10 cm to 44.83 m (ajustes band) — 4.33 m above the control line, roughly 43.3 days at the current pace
  • Day 22 of the metro rotation that began Aug 8; levels are read each morning from AAA’s own 5:00 AM chart for our reservoir board

Why this matters: The number that matters is the gap to the next band line: 0.14 m for Carraízo, 4.33 m for La Plata. Straight-line dates move every day — the daily check is the point.

Day 22 of the metro rotation. This morning’s 5:00 chart from the Autoridad de Acueductos y Alcantarillados shows Carraízo at 37.14 meters — down 6 centimeters from yesterday, and La Plata at 44.83 meters — down 10 centimeters from yesterday.

This is the 19th entry in our daily chart check (yesterday’s is here), built the same way every morning — from AAA’s own numbers, read off its charts for our reservoir board.

Carraízo: down 6 cm

Carraízo kept sliding. This morning’s chart puts it at 37.14 meters — down 6 centimeters from yesterday, in the ajustes band. The next line on the chart — into the control band — sits at 37.00 meters, 0.14 meters below this morning’s reading. At AAA’s printed pace that is roughly 2.3 days out (straight-line date: Sep 1 — a projection, not a forecast; one wet afternoon moves it).
