In the agency’s own words

Cottonwood Recreation Area is a day-use facility located in the tailwater area below Saylorville Dam. The 26,000-acre Saylorville Lake Project stretches over 50 miles up the Des Moines River Valley. The lake provides a wide variety of recreational activities, including boating, swimming, fishing, hiking and hunting. Keep reading

Recreation

Visitors come to Saylorville Lake for its great boating, sailing, water skiing, windsurfing and swimming opportunities. Anglers fish for walleye, wiper, largemouth bass, catfish, crappie and northern pike. The paved Neal Smith Trail winds 24 miles from Des Moines to Big Creek State Park and connects the campgrounds on the east side of the lake. It is designated as a National Recreation Trail and is used for biking, hiking, jogging, walking and in-line skating.

Facilities

The day-use area offers nine group picnic areas with water and electric hookups. Amenities include flush toilets, a volleyball court, playground and hiking trails.

Natural Features

Cottonwood covers a large open and flat lowland area bordering the east side of the Des Moines River. Wildlife is abundant throughout the project. White-tailed deer, turkeys, pheasants, waterfowl, and other small game animals roam the lands around the lake.

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.

Ask whether this could be a place to sleep

The agency’s own record files sites here and marks every one of them day use. The draft asks whether any could open to overnight camping, and if not, why.

To Zachary Nunn

Asks them to put the same question to the agency in writing.

Subject Cottonwood Recreation Area has sites, and nobody may sleep in them

Dear Zachary Nunn,

I’m a constituent in Iowa’s 3rd district. Cottonwood Recreation Area, Iowa carries 9 records on the U.S. Army Corps of Engineers’s own file, every one of them marked day use rather than overnight.

I’m asking you to put one question to the U.S. Army Corps of Engineers in writing: would they consider opening any of these sites to overnight camping, and if not, why not?

Road trips and camping on public land are part of how this country knows itself. It’s where a lot of people meet the place they live in for the first time, and it has never been something you had to be well off, or well organised six months in advance, to do.
