What this means

Water is short at Willow Creek Reservoir: the latest reading of 8,116.91 ft is below normal for mid-October.

That puts it 6.61 ft below the median of 8,123.52 ft for mid-October, based on 36 years of readings. A year ago it stood at 8,125.44 ft (−8.53 ft).

It is still going down, by 0.55 ft over the past week. With the water still dropping, the shoreline keeps moving out. The 30-day range is 8,116.78 ft – 8,119.63 ft.

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

Conditions at the shore change with the level, so check with the agency that runs the lake before a trip.
