What this means

Nothing unusual at New Melones Lake right now: the lake level of 1,004.22 ft is in the normal range for mid-October.

That puts it 2.58 ft above the median of 1,001.64 ft for mid-October, based on 36 years of readings. A year ago it stood at 1,015.62 ft (−11.40 ft).

The level is falling, down 1.15 ft over the past week. Over the past 30 days it has moved between 1,004.22 ft and 1,007.68 ft.

Lakes and reservoirs often sit lower in fall after a summer of evaporation and use, and recover with winter rain and spring snowmelt.
