We haven't personally camped here. Everything below is pulled from public land data, USGS maps and OpenStreetMap — a real place on public land, but not field-checked by us. Confirm road conditions, current access, stay limits and fire restrictions before you go.

Iowa DNR Wildlife Management Area — about 8,364 acres across 12 separate parcels, Butler County. Primitive camping is allowed statewide on Iowa DNR wildlife areas by rule — no permit, no camping fee — for up to 14 consecutive days, UNLESS that area posts restrictions on site (Iowa Admin. Code r. 571-51.11). The DNR can close any individual area to camping just by putting up a sign, and there is no statewide list of which ones have, so read the signs at the entrance and treat a posted restriction as final. Iowa DNR's own camping article also says to stay 100+ yards from parking lots, boat ramps and jetties; that sentence was dropped from the rule in the June 2025 rewrite, but it is still good practice and may be posted locally. These are working wildlife areas, not campgrounds: expect a gravel parking area and nothing else — no water, no toilet, no table, no fire ring. Pack water in and everything out. Much of this unit is marsh, river bottom or seasonally flooded ground — dry, level tent ground can be genuinely scarce and access roads can be under water in spring. Fall is a hard time to use these: Iowa's shotgun deer seasons and waterfowl season put a lot of hunters on WMAs, and blaze orange plus a different destination is the smarter call. The pin is a representative point inside the official DNR boundary, NOT a campsite or a parking lot — scout the actual access off the DNR atlas before you commit to it after dark.

How we know this

Source
Iowa DNR (wildlife management areas)
Confidence
Likely — The record is good enough to put a pin on, but thin in places. Treat the details as a starting point, not gospel.
How it was placed
Iowa DNR public ArcGIS, Boundaries/Public_Lands/MapServer/0 (programs.iowadnr.gov), TYPE=State Wildlife Management Area, MANAGER='DNR - Wildlife', all 12 parcel(s) OWNER='DNR'; outSR=4326, fetched 2026-07-20. Coordinate = centroid (verified inside boundary) of the largest parcel, so it is inside the official boundary. Independently cross-checked against OpenStreetMap/Overpass: matched 'Big Marsh Wildlife Area' at 3.1 mi. Camping basis: Iowa Admin. Code r. 571-51.11(481A) (IAC 5/14/25, ARC 9226C, eff. 6/18/25) — primitive camping allowed on all game management areas, 14 consecutive days, unless posted; r. 571-51.2 puts all DNR land in that class. No per-area camping flag exists in the GIS, so this is a category-wide rule applied to a verified DNR-owned unit → confidence='med'. Corps/USFWS-owned units excluded on purpose. Batch 1 (top 50 by acreage) of 396 qualifying areas.

Not verified on the ground. Nobody from here has camped it. It stays at Likely until someone does.

What we don’t know

A land record can put you within a few metres of a spot. It cannot tell you any of this — so check it yourself, and treat anything below as the open question it is.
