Our coverage

Water live: reservoirs, rationing plans and your sector

Day 15 of the metro rotation. This morning’s 5:00 chart from the Autoridad de Acueductos y Alcantarillados shows Carraízo at 37.46 meters — down 6 centimeters from yesterday, and La Plata at 45.42 meters — down 7 centimeters from yesterday.

This is the 12th 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 37.46 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, 0.46 meters below this morning’s reading. At AAA’s printed pace that is roughly 7.7 days out (straight-line date: Aug 30 — a projection, not a forecast; one wet afternoon moves it).
