Little Water Left in San Carlos Reservoir

OPERA's dynamic surface water extent layer and Landsat images show extremely low water levels in this Arizona reservoir in June 2026.
Pictured is satellite imagery of portions of Montana, Idaho, and Wyoming. Portions of the map are colored blue for areas of EMIT and SAR data masking. Yellow where there is landing cover masking. Red where high-resolution model training was used. Dots for training point data. And white to show the total area of analysis extent.
