These are estimates, not official measurements. Satellite imagery gives us a good general picture of reservoir levels between official readings, but real-world conditions (clouds, snow on the ground, reservoir shape) can affect accuracy. For official water records, contact NPIC at (970) 568-3612 or the Colorado Division Engineer, District 3 (Greeley, 970-352-8712).
