In the agency’s own words

Acorn Campground is a sunny campground in the brush-covered hills of the Sierra Nevada Mountains. The area is generally characterized by a warm, dry climate with summer temperatures regularly soaring above 90 degrees. With sites just a short walk from the shores of the popular New Hogan Lake, visitors will have no problem finding relief in the comfortable clear waters. Keep reading

Recreation

Boating is a popular pastime, with boat ramps conveniently located around the lake. The large surface area allows for plenty of water skiing, wake boarding, jet skiing and more. Year-round fishing for stripers, bass, crappie, bluegill and catfish is perfect for experts and beginners alike. Some of the largest fish are found in less than 25 feet of water. The "River of Skulls" hiking trail is located below the dam at the Monte Vista Recreation Area. There is also a staging area for an eight mile equestrian trail on a scenic loop that winds along the lake and through the foothill chaparral. Trail guides are available at the park office. Bicycle trails suitable for the beginner as well as the advanced rider are found on the west side of the lake and next to the group camping area. An easy 3-mile trail connects the park office with Acorn Campground. Hunting with bow or shotgun during the open season is permitted in certain areas of the lake. Upland game such as turkey, quail and dove is available and waterfowl includes a variety of duck and geese.

Facilities

Acorn Campground offers 128 spacious campsites with modern amenities such showers and accessible flush toilets, as well as drinking water, an important part of staying hydrated in the summer sun.

Natural Features

The 4,400 surface-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 was built to provide flood protection to the city of Stockton and water for irrigation, drinking and hydroelectric power, and it now offers recreation opportunities for thousands of visitors each year. The New Hogan area supports a wide variety of wildlife. The foothills location is home to grey fox, mule deer, coyote, turkey, mountain lion, bobcat and rattlesnakes. New Hogan is also a wintering home for bald eagles. The south shore of the lake has been designated as a wildlife viewing area.

Nearby Attractions

A number of historic sites are located nearby, including Carson Hill, the discovery site of the largest gold nugget ever found, and The Black Bart Inn, located in San Andreas, where the famous outlaw Black Bart was captured. Groceries, gas, camping supplies and more can be found in the nearby town of Valley Springs, California.

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 128 of the 128 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. 126 of the 128 sites listed carry one, and a site whose type has no published rate sits out of the price rather than being called free.
