Water level history
About Lake Gaston
Lake Gaston is a reservoir on the Roanoke River in Virginia & North Carolina, operated by Dominion Energy. Its full summer pool sits at 200 ft above sea level. Live water levels come from the NOAA National Water Prediction Service gauge at the dam and update hourly.
Understanding Lake Gaston's water level
"Full pool" is the elevation Dominion Energy targets when Lake Gaston is completely filled — 200 feet above sea level. Lake Gaston is a generation pool: Dominion Energy runs it to a licensed operating band around 200 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 Gaston 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 Gaston, 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.
