About 4,850 acres of water is impounded behind this dam on the Little Caney River. The Corps also holds fee to approx. 12,000 acres of land around the lake that is available for a variety of recreational uses including hunting,& hiking.
Reservations for Copan Lake are made through Recreation.gov. In peak season, the most popular campgrounds are typically claimed within minutes of each release — which is why the park reads as "sold out" for most of the year.
Sold out is not final, though. People book far ahead and plans change, so cancellations return to the official calendar throughout the season — with no announcement, at any hour. A cancelled site is bookable by whoever sees it first.
