Water level history
About Lake Sinclair
Lake Sinclair is a reservoir on the Oconee River in Georgia, operated by Georgia Power. Its full summer pool sits at 340 ft above sea level. Live water levels come from the NOAA National Water Prediction Service gauge at the dam and update hourly.
Understanding Lake Sinclair's water level
"Full pool" is the elevation Georgia Power targets when Lake Sinclair is completely filled — 340 feet above sea level. Lake Sinclair is a generation pool: Georgia Power runs it to a licensed operating band around 340 ft rather than keeping deep flood storage above it. That means the level answers to the day's generation schedule and to how much water is coming down the river, so it can move noticeably between morning and evening and still be exactly where it is supposed to be.
Lake Sinclair is normally held near its summer pool from spring through the recreation season, then let down over winter to the utility's cold-weather elevation so there is room for high water. Within any given week the bigger mover is generation: releases through the powerhouse pull the pool down and inflow brings it back, which is why a foot of daily swing here is routine rather than a warning sign.
The recent high and low above are drawn from the published history available for Lake Sinclair, so they show how today compares over that record rather than an all-time extreme. The 12-month and 5-year chart views make the trend and the lake's usual seasonal shape easy to see.
