In the agency’s own words

Carbolyn Park is located in eastern Kansas along Dragoon Creek, just east of Pomona Lake. The scenic park appeals to family campers, sportsmen and water sport enthusiasts. The reservoir covers 4,000 acres and offers excellent fishing and boating opportunities. Keep reading

Recreation

Fishing, boating, picnicking, and hunting are favorite activities on and around Pomona Lake. The lake's fish and wildlife resources provide ample opportunities for sportsmen and women. Three nearby trails meander around Pomona, providing visitors with hiking and nature study opportunities. Deer Creek Nature Trail and Witches' Broom Trail are short trails for hikers. The Black Hawk Trail offers a 33 mile loop with several trailheads. It is a popular hiking, horseback riding, and mountain biking path.

Facilities

Carbolyn Park Campground offers 32 campsites, 29 of which have electric and water hookups. Other amenities include flush and vault toilets, a shower building, playground, dump station, picnic shelter, boat ramp and numerous bank-fishing areas. The local sheriff's department and Corps of Engineers rangers patrol the park during the recreation season. A visitor center is located a short distance from the park and provides educational displays about the lake and its environment.

Natural Features

Pomona Lake is situated among the rolling hills, mixed grasslands, croplands and forests of eastern Kansas. Wildlife and numerous species of birds can be observed at this secluded, heavily shaded campground. Bald eagles, white-tailed deer, Canada geese, wild turkey, crappie, walleye, channel catfish and other wildlife can be found here.

Nearby Attractions

Numerous parks lie on the banks of Pomona Lake, offering additional boating, fishing, swimming, hunting, and hiking opportunities. The town of Lyndon, Kansas is less than 10 miles away, with limited restaurants and shops. This small town is home to 22 historical sites and the smallest Carnegie library still in use.

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.
Nearest place of any size: Vassar, KS, 2.4 mi WNW (a census designated place). Straight line.
