What changed at the monthly refresh

Each month the map takes in new readings and reruns the forecasts. This page lists, per GSA, RMS wells that crossed their MT, plan rules that changed, new record lows, and forecasts that moved 2 ft or more for the same month. Every GSA has its own page and RSS feed.

Forecasts use the NOAA outlook (CPC's Oct 2026 issue: water year 2027 at 122% of normal precipitation).
