About Grand Lake O' the Cherokees
Grand Lake O' the Cherokees is a reservoir on the Neosho / Grand River in Oklahoma, operated by Grand River Dam Authority. Its full summer pool sits at 745 ft above sea level. Live water levels come from the NOAA National Water Prediction Service gauge at the dam and update hourly.
Understanding Grand Lake O' the Cherokees's water level
"Full pool" is the elevation Grand River Dam Authority targets when Grand Lake O' the Cherokees is completely filled — 745 feet above sea level. Grand Lake O' the Cherokees is a generation pool: Grand River Dam Authority runs it to a licensed operating band around 745 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.
Grand Lake O' the Cherokees 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 Grand Lake O' the Cherokees, 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.
