Every site here is reservable, and the record lists none held back for anyone who drives up.
No availability snapshot inside the last 36 hours, so this page draws nothing rather than ageing a reading into fiction.

We read recreation.gov once an hour, at 40 minutes past, and write the first time a site in your window is free for the nights you asked for.
Scanners that check every few minutes exist, and most of them charge. This one is free, it reads the same calendar, and it won’t always be first.

What you actually pay
Derived by CAMPANAC: the agency’s published rates for this season, $38–$76 a night, plus one $8 recreation.gov reservation fee for the booking. A weekend here means Friday and Saturday night, booked once. Optional charges (an extra vehicle, a second tent, a dump-station fee) are listed separately and aren’t in this total.
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.

Toilet distances are OpenStreetMap’s, measured for 26 of the 26 sites listed. A site with no reading is unknown, never far.
The price is derived by CAMPANAC, not published per site: the per-night rate this campground publishes for each site’s own site type. 26 of the 26 sites listed carry one, and a site whose type has no published rate sits out of the price rather than being called free.
Measured shade is NLCD Tree Canopy Cover 2024 (USDA Forest Service / MRLC) read at the site’s own coordinate, 27% canopy or more, and only for the sites the agency gave no Shade value. It never changes the agency’s own shaded count beside it.
