The place

the agency’s own description · what’s there

In the agency’s own words

Spur 406 Campground is generally open year-round and rarely fills up, except possibly on holiday weekends. It may close on occasion due to high water events. A boat launch ramp off the campground may be available depending on lake levels. This campground offers 6 primitive sites, each with a covered picnic table and a BBQ grill. No ground fires are allowed. The sites are suitable for tents or RVs. Vault toilets are available. No drinking water or hookups are available.

Nothing to book, just show up

One of 1,623 federal campgrounds where the site still goes to whoever pulls in first, and a night costs $6 with nothing added. Get there before noon on a summer weekend.

recreation.gov publishes no availability for a campground you can’t reserve, so there’s no thirty-night reading to draw here. The season bar above is what the agency does publish.

Derived by CAMPANAC: the lowest per-night amount the agency’s fee record states ($6), and no booking fee, because this campground takes no reservations. A weekend here means Friday and Saturday night. Optional charges (an extra vehicle, a second tent, a dump-station fee) are listed separately and aren’t in this total.

The land, and who answers for it

Who answers for this land

Spur 406 Campground is in Texas’s 23rd congressional district. Whoever holds it votes on the laws that decide what happens to this land. See how its representative votes on public lands →

Our roster still carries Tony Gonzales for this district and the current federal record doesn’t list them as sitting, so we’re not naming a representative here until the two agree.

Cell signal: the Park Service’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.
