Gauge note
Target band: 3,000 cfs to 4,500 cfs · Des Moines River at Keosauqua, IA
Gauge context
Use the Des Moines River at Keosauqua gauge. Treat roughly 3,500 cfs as the preferred low-water exploring level, expect walking at 700 to 800 cfs or less, and avoid claiming a normal trip above about 6,000 cfs because the rock bars go under.

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.
