Lake Wylie water level, explained

The short version

100.0 ft is full. Duke Energy uses its own scale for the lake, and 100.0 means full pond.
Most of the year it sits a few feet below full, close to Duke's target, which changes through the year.
Below about 95 ft, shallow coves dry out and some ramps close.

The 100-foot scale

Full pond on Duke's scale is about 569.4 ft above sea level. So a reading of 97.6 means the lake is 2.4 ft below full, not 97.6 ft deep.

Target, not full

Duke usually keeps Lake Wylie a few feet below full. That leaves room to soak up heavy rain without flooding. Duke publishes a target level next to the actual one, and the target moves with the seasons.

Why the lake drops

Lake Wylie is one of 11 lakes on the Catawba River that Duke runs as one system. In a drought, Duke follows a basin-wide plan called the Low Inflow Protocol. It releases less water and asks people to conserve. Every lake on the chain shares the shortfall.

What the numbers mean at your dock

Reading	Below full	What you'll notice
99–100	0–1 ft	Very full. Watch for floating logs after storms.
97–98.9	1–3 ft	Normal for most of the year.
95–96.9	3–5 ft	Low. Shallow coves, more groundings, some docks sit on the bottom.
Below 95	5+ ft	Very low. Ramp closures likely. See boat ramps.

Where the number on this site comes from

We read the same data that feeds Duke's Lake View app. It isn't an official public service, so it can stop working without notice. When it does, or when Duke hasn't posted a new reading in 24 hours, this page says so instead of showing an old number.

For the official reading: Duke Energy's lakes page, the Duke Energy Lake View app, or call 800-829-5253.
