The ground at Apache Lake's coordinates falls inside the D0 area of the weekly U.S. Drought Monitor map. That describes local conditions — rainfall, soil moisture, streamflow — not the reservoir's storage. Arizona drought figures →
Data source: USGS National Water Information System (NWIS) — daily reservoir storage volume. Design capacity is unavailable for this site, so fill % is estimated against the 5-year maximum storage and may overstate fullness. Last reading: 2026-10-30.
