What this means

Shadehill Reservoir is below normal for mid-October, with the lake level at 2,265.29 ft.

That puts it 2.78 ft below the median of 2,268.07 ft for mid-October, based on 36 years of readings. A year ago it stood at 2,267.89 ft (−2.60 ft).

It has dropped 0.16 ft over the past week. With the water still dropping, the shoreline keeps moving out. In the last month it has stayed between 2,265.29 ft and 2,265.70 ft.

Many reservoirs reach their low point of the year in fall, before winter rain and snow start the refill.

On the water at Shadehill Reservoir

A receding shoreline opens up beaches but also uncovers hazards: stumps, rocks and soft mud that are usually well under water.

Wear a life jacket on the water. Most boating deaths involve people who were not wearing one.
