What "full pond" actually means
On Lake Keowee, full pond is 800 feet above sea level. Keowee is one of the most stable reservoirs in the Southeast — it usually sits within a few feet of full pond all year, so a reading a foot or two down is exactly what you want to see. That's why locals just say the lake is "at full pond" and go. (Duke Energy's own gauge reports the level as a percentage of a 100-foot scale, so if you see "97%" on their site, that just means 3 feet below full — same number, different dialect.)
Lake Jocassee, upstream at a full pond of 1,110 feet, is a different animal. Duke moves water down from Jocassee to Keowee to spin turbines and cool the Oconee Nuclear Station, so Jocassee's level swings a lot more. Seeing Jocassee well below full pond while Keowee is nearly topped off is completely normal.
Reading the ramp
For most of Keowee, anything within about 5 feet of full means every public ramp is good and the swim spots are deep. If the lake dips lower during a dry stretch, head for South Cove County Park in Seneca — its ramp is deep and stays usable when shallower ones start showing mud.
Is there a Lake Keowee water level forecast?
No — and be skeptical of anyone who offers one. Duke Energy publishes the current reading and its operating guidelines, but not a predicted level, because the two things that move this lake are hard to forecast more than a few days out.
The first is rain in the upper basin. Keowee's watershed drains a steep slice of the Blue Ridge escarpment, so a wet week upstream shows up in the gauge days later. The second is Duke's own hand on the valve. Keowee and Jocassee are a pumped-storage pair: water runs downhill from Jocassee to Keowee to generate power when demand spikes, then gets pumped back up when power is cheap. Those transfers are scheduled around the electricity market, not the weather, which is why the level can move on a blue-sky day.
What you can do is read the direction of travel. Watch the chart above — if Jocassee is dropping faster than Keowee, water is moving downhill and Keowee is being topped up. If both are sliding together, the basin is simply dry. And in a genuine drought, Duke can declare a Low Inflow Protocol, which is announced publicly and is the real signal that a deeper drawdown is coming.
Common questions
- What is full pond on Lake Keowee?
- Full pond is 800 feet above sea level (100%). Keowee normally stays within a few feet of it year-round.
- Why is the lake level low?
- Keowee is a working hydro reservoir, so the level moves as Duke shifts water to and from Jocassee. Drought or a declared Low Inflow Protocol can pull it down further — but rarely more than a few feet.
- Where do I launch when it's low?
- South Cove County Park, High Falls County Park, and Mile Creek Park all have deep ramps that hold up in lower water.
- What is the water level of Lake Keowee today?
- The gauges at the top of this page show the current reading straight from Duke Energy, updated continuously. Keowee typically sits within a few feet of its 800-foot full pond.
- Is there a forecast for the Lake Keowee water level?
- No official forecast exists. Duke Energy publishes the current reading but not a predicted one, because the level depends on rainfall in the upper basin and on Duke's pumped-storage transfers with Lake Jocassee, which follow the power market rather than the weather. The chart on this page shows the trend, which is the closest thing to a forecast you'll get.
- Where can I see a Lake Keowee water level chart?
- On this page. The graph above plots both Keowee and Jocassee over the last 30 days, 90 days, or the full record, from readings we log four times a day and keep permanently.
- What is full pond on Lake Jocassee?
- 1,110 feet above sea level. Jocassee is the upper reservoir of Duke's pumped-storage system, so its level swings far more than Keowee's — double-digit drawdowns are routine and the lake is still spectacular.
