In the agency’s own words

Post Oak is located on the banks of Copan Lake in Oklahoma's Green Country. Camping, boating, picnicking, hunting and fishing are popular activities here. Keep reading

Recreation

Copan Lake offers its visitors extensive opportunities for a memorable outdoor recreation experience. The lake is home to many species of game fish, including largemouth bass, white crappie, channel and flathead catfish, and various species of sunfish. Hikers and horseback riders enjoy exploring the area on 3 miles of trails that wind through the wooded and open meadows of the lake shore. 11,000 acres of land around the lake have been set aside for wildlife management. These lands are open for public hunting of deer, waterfowl, bobwhite quail, turkey, cottontail rabbit, and squirrel.

Facilities

This campground offers 19 sites with electric hookups. Amenities include flush and pit toilets, showers, drinking water, and a dump station.

Natural Features

The 4,850-acre lake sits on the Little Caney River among a prairie landscape of grasslands and croplands.

Who keeps the booking fee

The agency’s own policy text says the reservation fee and the cancellation processing fee are “retained by the reservation service contractor”, and that a campground concessionaire will decline to refund them because “they did not receive these fees”. Recreation.gov is run under contract by Booz Allen Hamilton. What share of your booking fee the contractor keeps isn’t published in any federal dataset we can read, so we print no number for it.

The price is derived by CAMPANAC, not published per site: the per-night rate this campground publishes for each site’s own site type. 20 of the 20 sites listed carry one, and a site whose type has no published rate sits out of the price rather than being called free.

OpenStreetMap has no toilet mapped within 1 km of this campground, so no site here carries a toilet distance. That’s a gap in the map, not a finding about the campground.

How we know

every fact on this page, and where it came from
Right now: recreation.gov is offering sites on 14 of the next 14 nights, which isn’t something a closed campground does.
Cell signal: the Army Corps’s own campground description, read as text by CAMPANAC. None of this is a measurement. It’s what the land manager published about the place, and phones, carriers and weather all disagree with each other; treat it as a warning, not a promise.
