    Does Cottonwood Campground have cell service?

    Yes. T-Mobile, Verizon and AT&T all report coverage at every site at Cottonwood Campground. That's the coverage each carrier reports to the FCC, not a measured signal, so under trees or below a ridge it can be weaker.

    How we know Sources and limits

    Shade, sun and Starlink are our estimates from Meta and the World Resources Institute’s canopy-height model (about 2 m pixels, from satellite imagery calibrated with space lidar; CC BY 4.0). From 2 m above each site we trace 72 lines out to 60 m and note the tallest tree in each direction. Shade counts trees overhead, the canopy within 30 m and how much of the afternoon sky is blocked. Sun counts how open the southern sky is. Starlink needs open sky above 35°, with the northern half counted twice because US dishes tilt north, and we keep the best spot within 8 m of the site’s post. The model sees tree heights only, not trunks, buildings or hills, so check with the Starlink app when you arrive.

    Slope is the ground at each site’s post over about 4 m, from USGS 3DEP 1 m lidar: level under 2%, gentle to 4% (most rigs level on blocks), sloped to 8% (fine for a tent), steep beyond.

    Cell coverage is from the FCC Broadband Data Collection (carrier filings as downloaded May 2026): each site is tested against each carrier’s modelled outdoor 4G/5G coverage. It is what the carriers report, not a measured signal.

    Weather is NOAA’s 1991–2020 climate normals for the campground. Sites and facts are from Recreation.gov’s open data (July 2026). Map imagery: USGS The National Map. Photos: Recreation.gov.

    From the campground’s Recreation.gov listing: “All 77 campsites have electric hookups, and all sites are reservable. Two modern shower houses with flush toilets are available for campers. A playground, horseshoe pits and picnic shelter are available within the campground and the adjacent Day-Use Area has a large reservable picnic shelter, picnic area, accessible fishing dock, disc golf course and a boat ramp for access to Lake Yankton. Nearby Training Dike Day-Use Area has a popular swimming beach on Lake Yankton along with access to the Missouri River downstream of Gavins Point Dam. A RV dump station is located just north of Cottonwood Campground off of Toe Road. Cottonwood Recreation Area is located in the in the lush golden chalkstone-lined Missouri River Valley. Many visitors to the lake area prefer to stay at Cottonwood because of the calmer, quieter waters of Lake Yankton, a much smaller lake of approximately 250-acres in size - versus the much larger Lewis and Clark Lake upstream of the dam. Lake Yankton provides excellent habitat for a variety of waterfowl and other bird species.”
