The place

the agency’s own description · what’s there · 1 notices

In the agency’s own words

New Hogan Dam and Lake is located in the oak- and brush-covered foothills of the Sierra Nevada Mountains. The 4,400 acre lake was created in 1964 with the completion of New Hogan Dam. When full, the lake has 50 miles of shoreline and extends nearly eight miles upstream to the confluence of the north and south forks of the Calaveras River. The dam provides flood protection to the City of Stockton (among other communities) and water for irrigation, drinking and hydroelectric power. The area is generally characterized by a warm, dry climate with summer temperatures regularly soaring above 90 degrees. Keep reading

Popular species caught in New Hogan Lake include striped bass, black bass, catfish, bluegill and crappie.

No reading yet, book on recreation.gov

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.

Free forever, no booking kickbacks.

What you actually pay

The sign priceU.S. Army Corps of Engineers
The U.S. Army Corps of Engineers publishes no per-night rate for this campground that we can read, so there’s no sign price to print. That’s a gap in the record, not a free campground.
The booking feerecreation.gov
Reservation fee, booked online$8
One fee per reservation, however many nights you book, and it’s non-refundable. $9 if you book by phone, $3 in person.
Pass discounts only apply to the recreation (or use) fee for the facility. Other charges such as electricity or water hookups, reservation or other fees are not eligible for a discount.
What a stay costs
The agency publishes no nightly rate for this campground, so there’s nothing to add the $8 booking fee to. We won’t total a receipt with a number missing from it.

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.

How we know

every fact on this page, and where it came from
Right now: U.S. Army Corps of Engineers publishes no season and no closure for this campground, and it takes no bookings we can read. That’s a gap in the record and not a locked gate: the number below is the only way to be sure.
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.
