Published Aug 28, 2026 · 787 Daily · Original analysis

Day 21 of the metro rotation. This morning’s 5:00 chart from the Autoridad de Acueductos y Alcantarillados shows Carraízo at 37.20 meters — down 6 centimeters from yesterday, and La Plata at 44.93 meters — down 11 centimeters from yesterday.

This is the 18th 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 37.20 meters — down 6 centimeters from yesterday, in the ajustes band.
