What this means

At 7,411.86 ft, Blue Mesa Reservoir is far below normal for mid-October.

That puts it 81.19 ft below the median of 7,493.05 ft for mid-October, based on 36 years of readings. A year ago it stood at 7,464.03 ft (−52.17 ft).

The level is falling, down 0.65 ft over the past week. With the water still dropping, the shoreline keeps moving out. Over the past 30 days it has moved between 7,411.86 ft and 7,413.93 ft.

Many reservoirs are drawn down through summer and fall; most of the refill comes later, with winter rain or spring snowmelt.

Swimming and boating at Blue Mesa Reservoir

Low water changes a lake fast for boaters. Some ramps get shorter or close, docks may be moved, and rocks and sandbars that are usually well under the surface come within reach of a prop.

If you swim, pick a spot with an easy way out, and remember that drop-offs move as the level changes.

How we check values

Each reading is stored as published. We hold back values that jump faster than physically plausible and show the measurement time with every value.
