----Loading--
DifficultyeasyThe route is short and generally beginner-friendly at lower levels, but old lock-and-dam remnants, riffles, exposed rock bars, and changing sand/gravel landings require attention. Treat very low water as a walking-and-scraping trip, not a clean float.
PermitsNone notedNo route-specific paddling permit is known. Follow Van Buren County, City of Bonaparte, and posted Lower Des Moines River Water Trail access rules at both ramps.
CampingOptions nearbyBentonsport Park has county campground facilities nearby, but treat camping as a separate reservation or county-park plan rather than part of the day paddle. Bonaparte is best treated as a take-out and town stop.
SeasonApr-OctLate summer and early fall often expose the rock and geode bars that make this route distinctive. Spring flows can still be paddleable, but higher water covers the bars and changes the trip from a slow explore into a broader moving-water float.

Access, shuttle, and map

Launch at Bentonsport Park and paddle the Lower Des Moines River downstream to Bonaparte Riverfront Park. This short historic-village segment is best when lower water exposes riffles, rock bars, and geode-hunting stops without making the route a scrape-heavy walk.

Start

Access caveats and watch for

Access caveats

  • Bentonsport Park is a county park with a public boat ramp on the Lower Des Moines River Water Trail, but the saved coordinate is park/access-area context rather than a ramp-survey point.
  • Bonaparte Riverfront / City Park is the public riverfront take-out context; use posted local signs for the exact boat-ramp approach and parking.
  • The Des Moines River is meandered here, but private property begins above the ordinary high-water mark. Keep stops to legal bars, public parkland, and clearly public access areas.

Watch for

  • Old lock-and-dam remnants and riffles near Bentonsport and Bonaparte, especially when low water exposes more rock.
  • Walking or dragging boats when the Keosauqua gauge is around 700 to 800 cfs or lower.
  • Rock bars disappearing and current getting less beginner-friendly above roughly 6,000 cfs on the Keosauqua gauge.
  • Large-river wind, floating debris after rain, motorboat traffic, and soft or muddy landings.
